1.5Ghz seems rather low for a VNA these days.
Is there a 3.2 and or 6Ghz version as well?

Post by: Neganur on March 09, 2018, 12:20:35 pm
3 and 6Ghz are probably not in the price segment they’re aiming this thing at. And there are tons of antennas in subgiga to use this one for I guess.

Why that picture is blurred except for the brand name though heh....not like you can see the specs by just looking at it. (Seems the picture was posted on Twitter, withou blurr)

Now this is interesting!

I was wondering how long it would take.

As a miniVNA Tiny user I am really curious. I know it has lots of limitations, but the price is unbeatable so far.

Although I imagine the price of this thing will be in the €/$1000 - €/$2000...

For the typical antenna adjustments the cheap VNAs are enough. I have a miniVNA Tiny and it works really well. If you are doing finer stuff like filters it’s a different matter of course.

What will be its dynamic range?

Actually it isn't really a bad decision for a combo device, as you can buy what you need. Also they already have a coupler for the SA range.

But _if_ it is the case there will be quite a bit of port swapping needed.

You don't need a system that uses an external coupler to measure S11.  The DG8SAQ VNWA is a two port vector network analyzer that will measure S11 up to 1.3GHz and it uses a resistive bridge internally.

The difficult part is the phase of S11 (or indeed of any S-parameter they are measuring) - how do they compare the phase of the reflected signal with that of their source signal?

Yes, I meant coupler or bridge.

It can also be done with a circulator or even a splitter. Circulators are normally not wide band, but  there is a older solid state design that Charles Wenzel has published for low frequencies and low power. It would be interesting to see how high in frequency that could operate using the fastest op-amps available now.

The phase comparison part is not difficult. Internally there would be a second, reference, detector which is fed with a portion of the TG signal. The detectors are just mixers and ADC's. The some maths in the FPGA and bobs your uncle.

Post by: KE5FX on March 10, 2018, 02:01:15 am
It probably has only two receiver channels internally instead of three or four.  They may have a single directional coupler (more likely a resistive bridge) on the main port to support S11 measurements, and a conventional non-directional ALC sampler on the TG port.  S21 measurements would be scalar only, implemented by treating the tracking generator output as a transmit-only "port 2." 

Not necessarily a bad way to go, at the right price.  But it limits your calibration options.  It had better be cheap... very cheap.

Post by: Neganur on March 10, 2018, 03:44:45 pm
You don't need 4 or two receivers to measure S21 - one is enough, and also phase can easily be measured with just one receiver if you compare the received phase to the phase at the TG output.

Implement a switching matrix (e.g. four RF SPDT switches) to change the DUT direction and then just have another switch path to select for reflection and transmission + the math.

Very crude compared to modern stuff but sure it works.

That is assuming the DUT doesn't affect the phase and amplitude of the TG. AFAIK most DUTs will affect the amplitude and phase of the TG so you'll need to measure the TG output while it is loaded by the DUT.

Could you elaborate how you think the phase is being affected and how is this relevant if you are comparing the phase at the input to the output?

It’s a relative measurement after all.

It's a cute idea, but you're not really making a relative measurement if you can't monitor both channels simultaneously.  Apart from phase noise and drift over time, toggling the T/R switch will inevitably cause slight changes in loading at both the DUT and coupler outputs that will prevent you from being able to calibrate the measurement properly. 

To get it working at all, my guess is that you will literally have to spend more money on isolation amps than another receiver would have cost. 

It's interesting, though, in the sense that really good DC-microwave switches are becoming readily available.  You could make some people at Peregrine Semiconductor very happy with this topology.

Post by: Neganur on March 11, 2018, 02:21:16 am
I'm not sure why you are being so dismissive. This topology definitely works. You just need to save several sets of cal data.
Like I said, compared to 4 receiver toplogy it's crude. But yes it works and was merely to illustrate how this could be implemented in for example the Siglent.
Especially if they already have the spectrum analyzer part and a tracking generator, then it just needs a few components more to make it a VNA.

Can it be compared to a PNA from Keysight, certainly not :)

Phase noise on the Rigol DSA815 isn't spectacular either. And how much does an ERA-33SM (https://www.minicircuits.com/WebStore/dashboard.html?model=ERA-33SM%2B) cost nowadays as isolation amp, $1.77 a piece?

Definitely not being dismissive, although I would've been before the PE42020 came out.  What you posted could very well be what they're doing. 

But through personal experience I've learned that there are very few free lunches in a VNA block diagram.  Spectrum analyzers are downright trivial by comparison. 

As you get up into the GHz range, isolation in particular is hard

AFAIK what makes things extra difficult is the fact that a 50 Ohm directional coupler works well for looking at a '50 Ohm system' but if you are looking at a system with an impedance of 1k Ohm or 1 milli-Ohm then the VSWR will be very far off anyway and thus measurement accuracy and resolution are going to suffer. I have a low frequency VNA (10Hz to 300MHz) and that offers various ways of doing measurements. I think this Siglent VNA will be handy for measuring antenna's and other typical circuits in the 50 Ohm or 75 Ohm realm but it may be less usefull for measuring milli-ohm impedances in circuit board power distribution.

Well, that's true of most VNAs, unless you have an RF I-V interface.  Even so, you're not going to be measuring milli-ohm impedances with a VNA.  The chart on page 58 of the following gives an overview of the frequency/impedance capabilities of various measuring methods:

Post by: G0HZU on March 14, 2018, 10:28:50 pm
'combo' analysers like this (based on a spectrum analyser) date back at least 35 years. The design of my old Takeda Riken (Advantest) spectrum analyser dates back to about 1981 and it has an internal tracking generator and came with the factory 'impedance' option fitted. This required an external Anritsu RLB as part of the option but it was capable of reasonable performance when measuring impedance. So it could mimic a basic VNA and it was also a very good spectrum analyser. In all the time we had it at work I don't think anybody used it as a VNA to measure impedance (because we had better alternatives) but it was used a lot as a spectrum analyser for critical testing up to 1800MHz.

Post by: Performa01 on March 26, 2018, 03:48:00 pm
Of course I am also interested in this instrument, so I’ve investigated a bit. Looks like this is a whole new design, but it will certainly take advantage of the experience gained with the SSA series. The base version is most likely to come as a spectrum analyzer with tracking generator as standard, hence can be used as a SNA (Scalar Network Analyzer) for gain measurements right out of the box.

More advanced measurements like VNA (Vector Network Analysis), DTF (Distance To Fault) and DMA (Digital Modulation Analysis) will be just software licenses, no additional hardware required.
There will also be the Advanced Measurements and EMI Pre-Compliance Test options just like with the SSA3kX.

 
1.5Ghz seems rather low for a VNA these days.
Is there a 3.2 and or 6Ghz version as well?

Not for now.


I guess market for lower end VNAs is not very big? If something like this would be priced so that its attractive to "average" Amateur Radio hobbyist, Siglent probably would sell orders of magnitude more....

We don’t know the price yet, so why starting to complain already?

There are still lots of folks buying the Rigol DSA815-TG, aren’t there? The new Siglent SVA1015X will cover the same frequency range, but with supposedly better specs, e.g. lower resolution bandwidth and lower phase noise. I don’t think the fact that this machine can be easily upgraded to a VNA, Fault locator and Digital Modulation Analyzer makes it less attractive for potential users.


Looking at the port labels I am guessing that it will need an external coupler for S11 measurements...?

So the explicit answer is no – and maybe that’s also one reason why the frequency range is limited to 1.5GHz. It’s pure speculation on my side, but I recon it would be difficult to cover an even wider frequency range with just one coupler or even bridge and for now Siglent sure didn’t want to have to switch between several of them – not to mention the increase in cost.

Yes it looks like it is built in. However building wideband bridge/couplers isn't the issue - if it was then having external couplers would be a logical solution :D

1.5Ghz seems rather low for a VNA these days.
Is there a 3.2 and or 6Ghz version as well?
Not apparently only the 1.5GHz version for western markets and a 1GHz version for Asian markets.

Yes of course. As I told BASE model is 1GHz. You buy it and then you buy things what you need. More os less handfull of options. Even VNA is option what need pay separately.

But still base model is 1GHz and my message only purpose was just answer for quy who wonder this Siglent "low" 1.5GHz limit. What is still more than R&S  base  model of FPC1500.
Not for start debate about R&S features and option. Only for show that even 1GHz comprabale equipment is lauched by A+ grade manufacturer just ago. No one is there to ask if it's a bit low just in the current years. As we can see name is important.

Siglent is going to be at the IMS2018 conference next week in Philadelphia with the SVA1015X.  After speaking with one of the rep's yesterday, I believe that it will also have mod/demod software options too.  I just hope it has QAM-256 to QAM1024 modulation upgrades with MER, preBER and postBER capabilities.

Is it really a new hardware or could everything VNA related (in theory) been implemented by software?

This a all off the cuff, but it might be theoretically possible to use the SSA hardware (with caveats) - as only one of the LO's is actually sweeping, and that same LO is downconverted and used to generate the TG output. I don't think the hardware is the same though.

Therefore the phase relationship - after power up - between all of the PLL's - might not change between the TG output and the SA input as it sweeps (assuming nothing is altered). Since the LO1 which is sweeping the TG is also used to downconvert the input, the phase of that doesn't need to be consistent.

To do an OSL VNA measurement you at a minimum need to be able to do four sweeps where the phase doesn't change. One for the open, one for the short, one for the load, and one for the measurement. The problem arises if you reset or preset the SSA, then all of the PLL's will come back up at different phases and so your calibration needs to be done again.

The other caveat is that there is only one input, so there can be no reference measurement. This means that any drift will directly impact the measurement.
Real VNA's have at least two receivers - one is used as a reference - and the DUT measurement is compared against the reference measurement.

As a point of comparison the Signalhound products cannot maintain the phase relationship between the SA and the TG as they sweep - because they are physically  different devices and only share a 10MHz reference, but don't share the same LO. They can make VNA type measurements at a single frequency (i.e. no sweeping) but the system only has only one receiver and so they have the drift problem above.

This could all be worked around somewhat using a solid state switch to provide a reference input and a DUT input and switch between them as needed to measure and correct for the phase issue on each frequency change, and it would also allow a correction for most of the drift issue. However the isolation of the switch would be an issue that would affect the measurement at some point and would need to be corrected for.

Post by: bson on June 28, 2018, 08:41:12 am
It should be possible to divide down the source output and feed it into a phase detector. As long as the frequency and phase are known the REF receiver shouldn't be necessary for basic 2-port measurements since the REF can be constructed from the DDS parameters, time, VCO phase detection, and cal data.  But, the devil is in the details and we ARE talking "measurement grade" quantitative correctness here, not a curve that "mostly looks awrite"...

SVA1015X is the top model in this series in which there is also a China market only model SSA1010X-C of 1 GHz capability.
I know of nothing else in development but it would seem to me the next step would be into higher frequency models based on the experience gained by the engineers in developing SSA and SVA models.
But I guess ATM they're busy with SDS5000X final development......

They will take all the hobbyist market, and sell a lot of these boxes... until  this happen sales will be slow as other competitors offer nice spectrum analyzers at about the same price

Siglent offers a set as calibration kit, from the data sheet:
"The F503ME mechanical calibration kit contains precision 50 Ω, phase-matched, type-N standards, used to calibrate Siglent vector & spectrum analyzers. Standards include a fixed 50 Ω termination, an open load, a short load, and a through adaptor.
The F503ME performance specifications are very similar to the Keysight 85032B mechanical calibration kit and it can be used as a replacement of 85032B."

Let's do a little summary on what kinds of applications this 1.5 GHz VNA would be useable. The ones I can think of at this moment:

- RF wireless remote controls (433 MHz is common)
- FM radio
- Amateur radio
- 27 MHz RC electronics
- GPS (marginally)
- UHF based CCTV cameras
- GSM radios
- RFID

Lots of applications really. But anything in the ISM band and 802.11ac WIFI is out. Other applications like RADAR are out, too, but those are not the target segment for this kind of device anyway.

Maybe others can chime in on what kind of applications this would be good for so that people can make better decisions :)

Maybe it's easier to day that anything that exceeds its bandwidth is out... there are quite a few ISM bands below 1500 MHz.
Lots of M2M (machine to machine, do I dare say IoT) uses the 865MHz/915MHz band for example, I'd imagine the VNA is sufficient for antenna measurements.

Just a few home projects I have shown on this site where I would have used it:

I am currently working on an active HV wideband differential probe that I could use it on. 

Designing custom made wideband HV single ended passive probes.
Redesigning the UNI-T UT210E current probe to increase it's bandwidth from 3KHz to 100KHz.
Designing your own HV differential probe.
Redesigning the Tektronix P6042 to increase it's bandwidth from 50MHz to about 100MHz. 

Looks like they support National Instruments, a must have.

Yes. 

I've thought about getting an 8753 but they are getting fairly old now themselves.  Then finding all the parts to put one together.  I looked at Copper Mountain a couple years ago.    With the help of Labview, the 8754A still does the basics for my higher frequency projects.

Was playing with it today shooting a teardown video. Seemingly fairly basic VNA capability compared with the USB ones with all their bells and whistles, but probably going to very usable for lots of apps. Shame that everything is optional extra though. Even the cal kit is like $360 or something.

In the middle of the teardown video, not there yet, but thought I'd post a preliminary teardown block comparison with the SSA3000
Not seeing much in the way of VNA hardware yet. Seems to be a lower frequency implementation of the SSA3000 as you'd expect, with IF ADC in the RF block this time instead of external.

Very nice, really helpful to see them side by side like that. Did you do a sneaky mirror on the images to make them match?

The only very minor thing I can see is the arrows from the First LO out to the TG on the main board should be going the other way.

Yes, I had to flip the image in order to match them up because the new ones has the components on the other side to the previous SSA3000 board.

Post by: TurboTom on July 07, 2018, 12:42:50 pm
Dave, thanks for the teardown, that was quite interesting.
A few things to add, some might be trivial and some rather peculiar:

In contrary to the high bandwidth SSA3000 series, Siglent doesn't use the special Rogers (or equivalent) high frequency PCB material but rather some impedance-controlled FR4. That way, it's much cheaper to produce and it makes complete sense to have an "almost" single-board solution for the instrument. In that regards, it's very similar to the Rigol DSA815 design which covers the same frequency range.

In Dave's video at 19:02, there's a close-up of the Port1 interface shown. Since I didn't quite believe that Siglent got along without a directional coupler for their VNA functionality, I dared to have a closer look, see the attached screenshot. There is a tiny multilayer coupler installed (similar to this one https://www.mouser.de/datasheet/2/400/tdk_02022018_HHM22152A2_ver4_1(Oct.2017)-1284660.pdf (https://www.mouser.de/datasheet/2/400/tdk_02022018_HHM22152A2_ver4_1(Oct.2017)-1284660.pdf)), yet highly surprisingly it's not located directly at the port but behind a switch and an impedance matching network / attenuator. I wonder how good the isolation/directivity characteristics of the circuitry are. If you look at the efforts the "big brands" in their boat anchors took some 25+ years ago to achieve really good directivity (see attached photo of an opened-up coupler of a HP 85046B test set, belonging to a 8753C VNA), it's hard to believe that despite all the advances in microcircuitry, manufacturers were able to shrink an assembly that much without sacrificing some quality/performance... I may be wrong, though  ;).

What's also quite peculiar is that apparently Siglent got away with a single receiver channel. In order to get a proper phase relation between the measured signal from the DUT and the output signal provided by the VNA, the VNA would have to make a correlation of a portion of the generator signal to the measurement signal. For that purpose, "classic" VNAs have at least two input channels, one of them labeled "R" for "Reference". Since the SVA1015X clearly has only a single channel (with some switching circuitry albeit), it must manage the comparison between reference and measurement signal via that single channel in a multiplexed manner, making sure that the generator's phase is stable enough while "looking" at the measurement signal that no siginificant phase error is introduced during that time.

Altogether, the SVA1015X appears to be a real "budget instrument", much more so than the SSA3000X and it's probably focused on the Radio Amateur or eductional market. Nothing wrong with that, I only agree with Dave that an instrument advertised as a VNA should include that function off-the-shelf and should not require the puchase af an additional, not really inexpensive option to be usable as a VNA.

Thomas

[...]yet highly surprisingly it's not located directly at the port but behind a switch and an impedance matching network / attenuator. I wonder how good the isolation/directivity characteristics of the circuitry are. If you look at the efforts the "big brands" in their boat anchors took some 25+ years ago to achieve really good directivity (see attached photo of an opened-up coupler of a HP 85046B test set, belonging to a 8753C VNA), it's hard to believe that despite all the advances in microcircuitry, manufacturers were able to shrink an assembly that much without sacrificing some quality/performance... I may be wrong, though  ;).

I thought the same last night after watching the video. Coupling will be horrible at the low frequency range, so I expect a low SNR. There is probably a reason for the lack of accuracy specs in the datasheet ;)

Quote
What's also quite peculiar is that apparently Siglent got away with a single receiver channel. In order to get a proper phase relation between the measured signal from the DUT and the output signal provided by the VNA, the VNA would have to make a correlation of a portion of the generator signal to the measurement signal. For that purpose, "classic" VNAs have at least two input channels, one of them labeled "R" for "Reference". Since the SVA1015X clearly has only a single channel (with some switching circuitry albeit), it must manage the comparison between reference and measurement signal via that single channel in a multiplexed manner, making sure that the generator's phase is stable enough while "looking" at the measurement signal that no siginificant phase error is introduced during that time
Looks like the same principle as Henriks's 200€ VNA:
http://hforsten.com/improved-homemade-vna.html (http://hforsten.com/improved-homemade-vna.html)

It's crude, but it does work.

Doesn’t require a full second receiver, all you need is to compare the phase out of the tracking generator to the phase at the input port.

In Dave's video at 19:02, there's a close-up of the Port1 interface shown. Since I didn't quite believe that Siglent got along without a directional coupler for their VNA functionality, I dared to have a closer look, see the attached screenshot. There is a tiny multilayer coupler installed (similar to this one https://www.mouser.de/datasheet/2/400/tdk_02022018_HHM22152A2_ver4_1(Oct.2017)-1284660.pdf (https://www.mouser.de/datasheet/2/400/tdk_02022018_HHM22152A2_ver4_1(Oct.2017)-1284660.pdf)

Yes, in principle you are right. But how does one (the instrument) "know" the phase at the tracking generator output?. After all the mixers, gain blocks and filters, even though in theory it may be possible to calculate it, you can not be sure to even getting close to the accuracy required for a VNA to provide reasonable results. You've just got to take a part of the output signal and analyze it to get the required phase information.

The "classic" machines do this by installing a dedicated recevicer for the reference channel. Some VNAs even use this reference channel signal to close the control loop of the generator PLL. Siglent uses a single channel receiver and implement a multiplexing switch at the input in conjunction with two isolating switches (to keep feed-through as low as possible) to couple either the output (Reference) signal or the reflected signal (S11) or the Port2 input signal (S21 or SSA) to the input of the receiver.

When arranging a configuration like that, you've got to be sure that the phase of the generator is stable within the required measurement resolution while the instrument evaluates the "other" channels. That's probably also the reason that the SVA1015X needs quite some time to draw a Smith chart or evaluate the phase / amplitude characteristics of a DUT. For every frequency point of the sweep, it has to analyze the reference signal, then switch to the selected input and analyze that signal, after that maybe (not sure if it's necessary) re-check the reference to make sure the phase is still valid. Compared to what I've seen in Dave's video, my ancient boat anchor 8753C is lightning-fast...  :D

Nice one - I was also looking at that part as the directional coupler/bridge and struggling to find a match for it.

I thought it might be a resistive splitter - which has tiny directivity - but can be corrected for by a factory calibration.
I still think there is a factory cal in there. Which, as long as things are stable, will make the directivity much better than the physical parts can deliver on their own.

The HP stuff has good directivity out of the box, with no factory calibration at all. It is pretty amazing how flat the traces are when you first turn it on.
I guess that back then it would have been considered poor form for a company like HP to put a cheaper component in there and correct for it with a calibration. Also then they would have the issue of where to store it, battery backed ram and all its failings, maintenance over the long term etc.

In contrary to the high bandwidth SSA3000 series, Siglent doesn't use the special Rogers (or equivalent) high frequency PCB material but rather some impedance-controlled FR4.

I noticed that too and I wondered if that is the reason that some of the filters are now built with discrete components?

[...]
I don't know how the Siglent in particular does it.

But you don't need to know what the value is at the TG nor do you need to calculate it. All you need to do is to use it as phase reference and compare the incoming signal against it with a circuit that e.g. can give you a voltage that represents the difference in phase.  I would like to believe the receivers in the mentioned HP gear doesn't "know" the phase either, just the difference and due to calibration knows what is 0 degrees (open) and 180 degrees (short).

Also, the reason to use multiple receivers per port is measurement speed (measure incident and reflected signal simultaneously) and the need to use any port as source and receiver. The Siglent does not seem to even sport a simple DUT reversal via a switch matrix (like four SPDT).

As to phase stability, Siglent does not specify it but you can probably measure it yourself and see how much/minute it drifts after a calibration.

If you like, there is an example of a simple 2-port VNA where essentially one port is only used as TG and the other port is only used as receiver: http://www.scottyspectrumanalyzer.us/msaanalysis.html (http://www.scottyspectrumanalyzer.us/msaanalysis.html)

The phase reference is a 10.7MHz signal that results from mixing the VCO signals of the 1st LO of the receiving channel with the VCO of the TG. Things are PLL'ed using the same reference oscillator. The signal that is used to measure the incoming phase is taken after the 2nd IF (10.7MHz) and passes through a logarithmic detector (has a square wave output). The following phase detector circuit then simply makes a relative phase measurement. Phase resolution is 0.1% or better.

Seems to me that the reference in this scheme is going to be the AtoD sample clock.  As long as you sample forward power, reverse power (for S11) and through power (for S21) at the same relative number of sample clocks to each other, then the phase error due to not sampling them at the same time should calibrate out.

So, I see a possible scheme as:

Select forward power for sampling.
Let it settle for Ns sample clocks
Take Nfft samples
Select reverse power for sampling
Let it settle for Ns sample clocks
Take Nfft samples
Select through power for sampling
Let it settle for Ns sample clocks
Take Nfft samples

Do FFTs on each set of samples to determine phase/amplitude at the frequency of interest.

Note that the delay between each set of samples is Ns + Nfft which is a fixed phase error for the frequency of interest.  It's not really different to calibrating at the end of a really long cable between your test port and device under test - the samples representing the reflections from the end of the cable are delayed in time.

So, I don't see the sample clock varying significantly while sampling one frequency (or more likely set of frequencies represented by the FFT).  However, should it drift over time, it would invalidate any stored calibration values... but stored calibration values are always suspect on a VNA anyway.  You should always recalibrate before taking any set of measurements that matter.

As for the cost of the Siglent calibration kit and the fact that it's not included, one cannot complain.  The big VNA manufacturers don't include cal kits and a Keysight "Economy" N connector 6 GHz cal kit will cost you US$ 891.  A Kirkby Microwave kit is currently $584 shipped in the UK!  But you don't need these for 1.5GHz... a lower quality kit at a lower price would be fine for 1.5GHz.

It has to be said that the quality of your measurements depends on the quality of your cal kit.  You can't measure a return loss of 50dB if your load has a return loss of 40dB!  If you do measure 50dB after calibrating with a 40dB load, all you can say is the return loss is 40dB or better, subject to the VNA's measurement uncertainties.

Actually I think that the "quality of your measurements depends on the quality of the characterisation of your cal kit ".
As long as you have good data for your kit, then theoretically the actual standards themselves don't matter much.

Particularly true now that full S param files can be used on a computer, instead of the C0,C1 etc in approximate curve fitting in the VNA.
You can literally use anything as long as you have an S param file for it.

I'd be pretty sure that Siglent's (relatively cheap) cal kit isn't that well characterized.  I guess we need some more data on it.

Let's see if I can make some of the SVA features work......maybe if I really knew what I was doing.  :-[
No study, no reading of the manual and only stumbled around in the UI to gain some little familiarity ......and watched Daves teardown vid.

Cold turkey antenna improvement exercise.

Background.
Some good few years back after a bit of study I wanted to extend the ~2-300m range of a wireless setup I have to control a 3 phase water pump and I needed 500m range to use the tiny remote from my house.
I built this from stuff I had on hand but in error made the copper monopole for 1/2 wavelength of 433 MHz when actually the system is 315 MHz.  :palm: It has no ground plane only a galv tin roof nearby. ~2m coax to a BNC connector close to the 4ch receiver.
So let's quickly confirm the transmission frequency in SA mode with just a coax RF loop.

(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=479882)

Existing copper monopole.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=479888)
In short, it was bloody useless and the antenna was unplugged and replaced with a ~200mm stainless welding wire that amazingly worked quite well at the full 500m. (tongue stuck out and standing on one leg) Run in this mode for many years.  :phew:

Stainless monopole
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=479894)




Can we improve on it now we have an SVA ?
Select VNA mode.  ???
Let's see how bad the existing is  :scared:

Existing R
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=479900)
Existing SWR
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=479906)
So for 315 MHz the existing 1/2 wave 433 MHz monopole is too short as it needs to be ~475mm so let's try 1/4 wavelength 315 MHz that works out at ~952/4 = 238mm
http://www.onlineconversion.com/frequency_wavelength.htm (http://www.onlineconversion.com/frequency_wavelength.htm)
Results below, not great but certainly an improvement.

Shortened R
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=479912)
Shortened SWR
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=479918)

So next to reinstall the antenna and see if it works at range........suspect it will need more tweaks yet......... TBC

If so, that does not look like a DIpole (2-pole) but rather just a 1/4 wave whip, or what should be a quarter wave. A dipole does not need a ground plane (because it has 2 poles already) but this one does. It looks like it is mounted on a metal box, that could be enough for a ground plane. Anyway, looking at the SWR and the picture I think there is some metal behind the antenna isn't it? That is why your SWR sucks, the metal is reflecting the signal back to the antenna.

You can easily convert it to a groundplane antenna by using 3 or 4 equal length wires connected to the coax shield and pointing down like this:

Yeah I know, it's shit.

The copper rod is pressed into the turned nylon bush and the coax center connected below.
I'll turn another step on the nylon bush and connect the braid to some mesh that sits on the step.
Not sure what I have for the mesh and that will entail a rummage around in the morning. I have heaps of 1/4" copper rod but setting ground plane 'fingers' up so they'll withstand the weather is troublesome in my mind.
I think it'll be easier with mesh....I'm sure I have some perforated mesh somewhere as I'd rather not use the 3/4" chicken mesh that I've got plenty of.

I made all this years ago and now with a SVA I have the chance to get it right.
The short length of stainless sitting in the BNC socket works so well as the control cabinet provides the ground plane and it still receives transmissions even though it's in a tin shed.  :o The hockey stick monopole is just LOS from where we send the signal from inside the house.

Thanks for the pointers, I'll sleep on them.  :)

I still think calling it a 'monopole' where your second pole is the ground plane is weird, but anyway…
Please keep in mind that the link points to a 2.4Ghz antenna, your ground plane needs to be 10 times bigger to be as effective. Also, it radiates slightly upwards and I don't think you want that? A vertical dipole radiates horizontally.

Call it a whip then and what's your advice to improve it's performance ?
Go from 1/4 wave to 1/2 or full wavelength ?

1/4" (6.25mm) copper rod is my preferred mast material. 952mm is full wavelength and this copper is reasonably stiff but the only concern is the nylon bush it's mounted in for full wavelength.

The most basic antenna is an open dipole, which you can mount horizontal or vertical. Horizontal will give you a radiation pattern like the figure 8, vertical will be a circle.
So 2 1/4 wavelength elements mounted on a small isolator, coax conductor to one element and shield to the other. The problem here is to mount it on a pole, you can't tape it to a conducting pole but you should stay clear of conducting materials in the radiating direction for a few wavelengths. If you want to use a vertical dipole on the existing mast I think your best bet would be to put the dipole in a pvc tube and mount that on top of your mast, keeping it at least 20cm away from the top of the mast. The problem here is feeding the coax to the antenna without disturbing the radiation pattern.
So that is why a ground plane antenna is easier, you can simply mount it on top of the mast.

SVA1015X is already the top BW model in this range so I'm fairly sure BW can't be improved. Owning both (as demo models) they're aimed at different markets due to their differing capability. If the VNA capabilities are of use and 1.5 GHz is enough to meet your SA BW needs the SVA1015X is the one to go for.
Happy hunting.  :)

An issue I have is it needs to receive transmissions from ~130o different directions which is why I originally settled on a monopole/whip that don't have the same directivity constraints.
There's zero transmission requirement as only reception is needed but I do understand that T/R performance is approximately equivalent.

A basic J-Pole antenna might be the ideal choice here. Easy to make and easy to match and it gives a low angle of (omni) radiation.

It is about 3/4 wavelength long and you can make a skinny version from 300R ribbon feeder (this is the Slim Jim folded dipole version) and hide it inside a hollow plastic tube. So you could replace the hockey stick with a longer plastic tube and put the antenna in the top section and feed the coax up the bottom of the hollow tube.

Note that the J Pole (or the Slim Jim variant) doesn't need a ground plane so this is why it might be a good choice for you here.

Thanks, yes maybe.
I'll run some numbers through this:
https://m0ukd.com/calculators/slim-jim-and-j-pole-calculator/


Edit
First look seems real good for 315 MHz with a leg separation of 21mm and total length of 686mm.
Might just fit inside some 32mm waste pipe with an end cap on the top. 40mm would give a bit more certainty of fitting but at the risk of higher wind loads on the base mount.
Maybe I'll thread the top of the 1/2" galv pipe hockey stick and use 'off the shelf' adapters to fit the waste pipe.....or build it again from 3/4" galv pipe for additional strength as there'll be a bit more windage to deal with as opposed to just a bare element.

Hmmm, off to do some measurements and scavenge though my numerous bits and bobs stashed away.

They are easy to make although many people tend to scrimp on the RF connections and end up with something with (soldered) RF connections that will fall apart over time. Also, it's worth fitting something at the antenna feedpoint to choke RF away from the outer of the coax feedline. If it ends up inside a skinny plastic water pipe then you might as well just make the basic J Pole version as there's little/no performance advantage with the folded (Slim Jim) version. They should both radiate as an omni vertical dipole with no need for a ground plane.

I guess the alternative would be to attach ground radials to your existing monopole antenna. I don't think there will be much difference in RF performance between any of these options and it really is a case of which version you prefer to build (and look at). However, if you build it well, the J Pole version inside a plastic pipe should be the most weatherproof... but you do have to make solid connections from the coax to the antenna if you want something you can fit and forget for many years.

You should be able to fit it inside a 18mm or 22mm diameter plastic pipe. 32mm is very wide!

Yes and after enlarging the J type pic I see the gap (F) spec is OD so yes it will fit into something smaller.
'Gap' put me crook thinking it was the gap between elements when it's actually an outside measurement.  :phew:

The feed points I'd experiment with and maybe with two sliding brass custom terminations that can be fixed permanently once the assembly is tuned. I can easy spin something up on the lathe and drill and tap it for termination and retaining screws.

I'm gunna feed it with coax as the run is a couple on meters and I haven't got ribbon cable on hand.
I might change the existing coax to one with a more robust middle conductor that I can sleeve and bootlace terminate.
The braid will be easy to just sleeve and retain the barrel choke in the right position with two cable ties.

I'll be a while before I post anything more on this as obtaining the bits and engineering will need to be factored into any spare time I get.  :(

Yeah, I'm liking the J pole antenna more and more.  :)

I think Tautech exploring the SVA1015X and his antenna is great.
As an example of something closer to what you're aiming for with your antenna here are two shots of a 1/4 whip antenna designed for the 70cm(430-450MHz) ham band, displayed in SWR and on a smith chart.

Thanks, I hope I'm not displaying any excellence as I'm a bit out of my depth but having a pile of fun learning.

hendorog helped me get a heap closer to optimum today when he dropped by to grab the SVA for some hardcore checks against his SH and Agilent. We explored just a small bit of the total functionality and checked his SMA Cal standards against the SVA factory setup. Changed SVA Cal to hendorog's kit and back again to factory default. Easy peasy !
Log Mag mode was something he showed me today and the dip in the sweep frequency where the antenna is the most emissive can be of great assistance for tuning this J Pole. I'll document more about the HW later as it's been changed and simplified. 3.2mm brass welding rod now with custom sliding feed points. (hint; 3.5mm chocolate block inners)
Getting some more antenna project bits tomorrow.  :)
When I get time I'll carry on with just the SSA and an external bridge then park it for a bit until the SVA gets back for final antenna optimization.
Think I'll order some more SVA's.............

hendorog will show just what it's capable of far better than I can.  :(

He left here like a dog with two tails.  :D
Now I'm hoping he'll give it back. :-//

An example which shows early preliminary measurements from a new bare J Pole antenna.

Your early plots don't look right to me so I had a go at making a very basic J-Pole at about 315MHz.

I used 2mm diameter copper wire which is a bit thin but I didn't want to waste the thicker stuff. So my antenna is a bit wobbly and needed supports to keep it stable in terms of tuning and alignment. However, see below for an image showing the complex impedance and the S11 plot and VSWR. I didn't bother to trim it for 315MHz so it is showing the best VSWR at 302MHz. I didn't do anything special in terms of optimising the lengths and just went for 3/4 wavelength overall and 1/4 wavelength for the J bit and I did this very casually to something like +/- 10mm. I then optimised the feed point on the VNA for lowest VSWR.

Note that the VNA reference plane is set right at the connection point to the antenna wires so the complex impedance graph is at the far end of the coax as it connects directly to the antenna wires.

Someone with more time on their hands could optimise the various antenna dimensions better than this but the plot below would be good enough for me for a basic J-Pole lashup  at 302MHz :)

Yeah they're miles off mostly due to basic newbie mistakes that were explored yesterday with hendorog.
I'm using 1/8" brass now but still in a 32mm PVC tube so I can still go back and build something with the 1/4" copper rod I have lots of.
The 1/8" brass is in just 1m lengths and a trim to the 1/4 wave section (correct calculated length) came up just a few mm short of where it should've been cut.  |O  We proved it was wrong by adding a bit back with a cable strip connector. This where it seems the Log Mag mode seems great for getting onto the target frequency.

The 200mm stainless whip in the BNC socket worked fine again this morning.  :phew:
Thanks for your pointers of help guys.  :)

I had a play last night when I got home. I did some unscientific tests of the drift and the directivity.

So far the drift after a cal looks OK. It looks to me like it has around 40dB of 'worst case usable' directivity - I did a calibration straight after power up and then waited an hour or so.

Probably the switched time division sampling of the reference (TG output) and the measurement has something to do with this.

The out of the box directivity with no calibration seems pretty decent too. I'll test this again to make sure I am not being fooled by it saving my last cal as we did set it to restore last settings on power up.

First impressions of the VNA software is that it is basic but stable. There are definitely features that have been held back - i.e. greyed out. These will no doubt come in due course. I wonder if Siglent have intentionally gone with a limited feature set for the early release to ensure stability?

I also had a quick play with the SA features. It is much more feature rich than the VNA side right now and I don't know if I am imagining it but I think there are even more options on the trace math page than the SSA has. The power math looks useful as it can be used, with averaging, to drop the noise floor.

I received my sva1015 last week and have been having fun getting to know it.  However I'm having a bit of trouble with the analog modulation analysis option and I'm wondering if anyone can provide some help/guidance.  I'm not sure if the issue is with my setup, theory, expectations or some combination thereof. 

I want to be able to do some FM deviation measurements, so I wanted to start by making sure I could get (what I believe to be) the correct values with a controlled setup. 

I've tried several different setups and I'm getting similar results from each of them, so I'll describe just one of the setups.  I have an amateur radio VHF/UHF transceiver connected to a Bird 4431 wattmeter which has an RF sample port.  The output of the bird is connected to a 50Ohm dummy load and the sample port is connected to the SVA1015.  For the modulating signal, I'm using the waveform generator on my SDS2204X scope, connected to the audio line-in on the data port of my transceiver. 

The waveform generator is sending a 1.2kHz sine wave onto a carrier at 144.41Mhz, and I used the spectrum analyzer functionality to adjust the waveform generator's amplitude until I hit the 1st order Bessel null.  This should be a modulation index of 2.4 and thus a frequency deviation of +/- 2.88kHz.  I also double-checked the deviation using the spectrum analyzer via the min/max trace differential and got the expected 2.88kHz deviation.  So I'm pretty sure the signal's FM deviation is indeed 2.88kHz. 

But when I enable the analog FM modulation mode, I can't seem to get it to give me that result.  I've tried every value of IF Bandwidth available, as well as every EqLPF.  I've tried both with and without averaging.  None of the values (min, max or average) are showing a deviation of 2.88kHz.  And the signal on screen is a bit more wonky than I'd expect.  It does sort of, mostly, show what looks like the 1.2kHz signal but it's not clean or consistent at all.  I've tried moving the SVA1015 away from the transceiver and the dummy load in case there was some noise getting into the machine from them, but that didn't seem to have any effect. 

Is there something I'm doing wrong?  Any advice/suggestions? 

BTW - I want to give some kudos to Siglent's support staff.  There were some issues getting my option licenses installed, which was exacerbated by the fact that the analog modulation analysis option was not enabled under trial license.  The tech support stayed late on friday waiting for the corrected codes to send to me so that I could do the work I was expecting to do over the weekend. 

One other side note for anyone looking at using the vector analysis functionality, their calibration kit is back-ordered and won't be available for roughly another week.  So unless you already have an appropriate calibration kit, you won't really be able to use the VA functionality for a little while.   Of course you can play around with it, but you can't *really* use it without proper calibration.

I just tried to replicate your setup quickly with a signal generator - I have to go out now, so didn't have time for screenshots etc.

Things I observed were:
* Level reading 3.4 dB when signal was 0dB. Channel power measurement on SA funciton showed 0dB.
* Not able to get a stable deviation reading in Demod mode for low FM deviation values. Above about 4 kHz I could get a stable reading using averaging, but it was always about 30% below what the signal generator was saying.
* I tried the min/max measurement in SA mode, but I'm not familiar with it and didn't have time to research it. It also read a different value but that is probably my fault.
* The Occupied bandwidth measurement function on the SA closely matched the FM deviation setting on my Sig gen.

I can look into it a bit further for you later on - let me know if there are any other tests I can do.

Thanks for running the tests.  If it can't give stable values below 4kHz deviation, that certainly limits its functionality (at least for me).  My usage is primarily with transceivers using a max of 5kHz deviation (and it's usually a bit lower than that), and it wouldn't be helpful at all while testing in narrowband mode (2.5kHz deviation). 

But at least with my setup I still can't seem to get any stable results even at roughly 4.5kHz deviation (which is the highest deviation I can get out of my transceiver).  I was able to get a much more stable visual display if I used 4kHz as my modulating frequency, though it's showing a weird component at the start of the trace which I don't believe is part of the signal.  But I'm still not getting stable deviation numbers.  I'll try to get some screenshots in the morning in case that helps diagnose my issue.

Strange thing is the MIN deviation shown seems quite repeatable.

When the SG is set to 1.88 kHz FM modulation, the Min value consistently shows 1.3 kHz deviation on the SVA.
When the SG is set to 2.88 kHz FM modulation, the Min value consistently shows 2.0 kHz deviation on the SVA.
When the SG is set to 3.88 kHz FM modulation, the Min value consistently shows 2.7 kHz deviation on the SVA.
When the SG is set to 4.88 kHz FM modulation, the Min value consistently shows 3.4 kHz deviation on the SVA.
When the SG is set to 5.88 kHz FM modulation, the Min value consistently shows 4.1 kHz deviation on the SVA.
When the SG is set to 6.88 kHz FM modulation, the Min value consistently shows 4.8 kHz deviation on the SVA.

I repeated the pattern starting at 1kHz, with 1 kHz steps and it is consistent.

Applying these rules results in a sensible value:
Over 5kHz deviation you can read the average value and divide it by 0.7 to get the correct deviation.
Under 5kHz take the MIN value and divide it by 0.7 to get the correct deviation.

So perhaps you can get the signal going then hit restart measurement and remember the value.

My Signalhound in analog demod mode shows +/- deviation values which are about 1% less than the SG setting, so I'm reasonably confident that the SG is outputting something sensible.

Do you mean S11 phase? The S21 phase won't be measuring anything with an open and/or short connected.

Anyway, that can be done now, without waiting for the official cal kit. This is because the Siglent cal kit characterisation data is already installed in the analyzer. So any open short and load will show exactly the same trace as the official cal kit will - as the data pre-set in the analyser defines 'what they are'.

Anything else that you measure will show a different traces if you cal with different kits. But measuring the parts in the kits themselves will show the same traces as they just reflect the cal data in the analyser.

Modulation is working much better. Deviation now works as expected.
Modulation rate also now works. Previously it showed a constant number IIRC.

This pic is with 0dBm input, AF modulation of 500Hz and FM modulation of 2kHz set on my old Marconi 2019A (uncalibrated)

The SA function shows channel power of about 0dBm, whereas the modulation function is showing carrier power of -3.42dBm so am not sure if that is showing an incorrect value or if I am just ignorant on something.

Changing the filter setting definitely makes a difference now.

Well done Siglent, a significant improvement there.

VNA function is clearly improved as well.
* As noted the sweep speed is about 5X faster. Now about 1 second.
* Start freq for VNA still seems to be 10MHz minimum. I have tried various things but I don't think that has been resolved with this update.
* There are now three cal kits which can be selected: F503ME, 85032F, 85032B/E
* Modify cal kit is still disabled, and port extensions are also still disabled.
* Trace export is still missing. This is a big feature as it enables many things. It should support CSV and s1p files as a minimum.

All in all this looks much improved. Commendable in such a short time frame.

open, short and load traces for the default cal kit are attached

Edit: fix pics

Here is a pic showing the post cal repeatability with 10x averaging turned on

The open is just an open SMA port - so no connector repeatability error.
The short is an SMA short - so that has connector repeatability error.

This is many minutes after calibrating and after several connection cycles for the various screenshots done earlier.

Note that the minimum scale is 1dB/div which needs to be fixed.

In summary I think the two big ticket items still missing are:
* Trace export function in CSV and s1p formats.
* Fix the VNA sweep to support frequencies below 10MHz.

I think the VNA function would be really improved by adding those two features. Also it would appeal to a wider audience and so generate more sales.

Thanks for testing and reporting on the update.  I saw it last night and was hoping it would fix the modulation analysis issues described earlier.  I briefly tried to install it, but it failed, possibly because I was trying to install the update over the LAN instead of via USB.  It *seemed* to work initially.  I was able to point it at the proper update file, and it seemed to load it, but then it said the file format was unsupported.  I set that to the side at the time because I had some other tests I needed to get done.   I was going to try the update again some time today after I dug up a USB stick in my pile of stuff. 

Regarding your comments about the "issue" with the VNA not going below 10Mhz ... I thought the specs actually stated that the VNA was only supported from 10Mhz and up.  Is there a particular reason you think this will eventually be "fixed"?   Of course I would love it if it went below 10Mhz, as that would allow usage on the bands below 30m.  I was figuring I'd have to get a return loss bridge so that I could at least do scalar measurements at the lower frequencies.  Which brings me to another question I had, which is whether it's possible to use a return loss bridge and still enable some of the network analysis measurements/calculations (similar to the reflection/vswr option on the SSA3K devices), or if I'd have to do the measurements/calculations by hand the "old fashioned" way?   

Also, I was curious about the EasySpectrum software.  The download page only lists it for the SSA3K devices and not for the SVA.  Does the same software work on the SVA or have they not released it yet for the SVA?

* Start freq for VNA still seems to be 10MHz minimum. I have tried various things but I don't think that has been resolved with this update.

When tautech posted the changelog for this update he said "expand the minimum span from 10M to 10 kHz", so that is not minimum frequency unfortunately. I wouldn't keep up your hope too high, it is probably a limitation of the hardware.

I think the coupler(s) may be the reason for the low er (10MHz) limit.

I am sort of surprised it works at that frequency.

Looks like a decent SA, but I am not really sure about the VNA part.
It misses the Ham market with its lower frequency limit, and misses the professional market with its upper frequency limit.
Its really over priced. Somewhere between free and $200 for the VNA option would seem about right.

Unless they can surprise us, and get the lower VNA frequency limit down to (say) 1.5MHz. The PCB material really limits the upper end.

Successfully updated to the latest firmware using the USB. 

Modulation analysis does indeed seem to be fixed (or at least vastly improved).  The totally wonky demodulated signal display is now fixed (I really should've taken a screen capture before updating - the waveform was clearly messed up in very interesting (and physically impossible) ways). I see the correct demodulated waveform now.  And the deviation now appears to be giving the correct result.  Woot!  That makes my life much easier. 

VNA is indeed much faster now.  I do find it a little curious though that the span can be reduced to 10kHz despite that it seems the RBW is fixed at 10kHz (maybe I'm wrong and/or it's just a misleading display - if you go to RBW it shows 10kHz greyed-out) .

Oh yes you guys are both right. I misread that point in the changelog.

 I do hope it isnt a hardware limitation though. I am not sure what the problem is though - as with this architecture any phase sync errors in the plls are cancelled out.

 I havent played with the scalar side yet, I will post a pic of it .
 I will also have try the easy spectrum software.

Hoping for some clarity on the minimum BW later today.
We can all see 10 KHz listed in the changelog and based on hendorog's findings with my unit I sent Siglent an email yesterday looking for an answer on this issue.
EDIT
Reply from Siglent.
My misunderstanding, 10 KHz IS new Span, improved from 10 MHz.

* Start freq for VNA still seems to be 10MHz minimum. I have tried various things but I don't think that has been resolved with this update.

Then again why would it even be mentioned in the changelog as something Siglent has addressed ?

Yep, I forget that this has a tiny chip coupler in it. Because it has a factory cal it always looks good, and you never see the directivity of the actual device. There is a little bit of noise creeping in close to 10MHz on those traces I posted yesterday, so you are probably right.

I also thought that it would miss the Ham market, but as nautiboy mentioned there is the scalar option with the tracking gen so it's not so bad.

There is also potential for making a simple external transverter. If they add the ability to export the measurement data from Port #2 then that could be used with PC based calcs to cover the full range.

The upper end is locked in for this device so it wouldn't make sense to use a high frequency PCB material. But there will likely be higher frequency units to come as the base platform is so similar to the SSA.

I thought they had changed the minimum possible start freq of the sweep - and that is still 10MHz after the update.

But they have actually changed the minimum span in VNA mode - which was 10MHz, and is now changed to 10Khz.

So yeah, that was an oops on my part.

Yeah, pretty much a computer.   :)  Not shown in the video, but I love the fact that it's running a VNC server.  I can just point my VNC viewer at it and monitor and control it completely remotely.   You can do something similar by pointing a web browser at its webserver, but I've found I like the native VNC interface better.  I can sit on the couch sipping scotch monitoring and controlling the analyzer up in my office.  Heck, since I can VPN into my network from anywhere, I could be sitting at the beach running tests.  Now why one would actually want to be running spectrum analyzer tests while on the beach, well that's another question, though I ask you whether you'd rather run them in a cramped, hot office or sitting out on the beach.  8)

Even with my bad english he tell clearly what he demonstrate. You can use mouse and keyboard.

Also perhaps he is accidentally demonstrating something what looks weird or like bug.

Time position 59s - 60s happen something what I can not understand without further info. (Perhaps Jason can tell?)
as can see there is RBW 1MHz and attenuator 20dB (and ref level 0dBm) and trace is around -60dBm what is ok.
Then his hand do "something"
and after then
Same RBW but now attenuator 30dB. look now where is 0dB (left side scale) There need read now reference level 10dB (but there read 1.0dBm - why?)
But then. If you look noise level now, it is around -40dBm. 10dB attenuator step produce noise level 20dB step. It is weird.
First it looks like step is 10dB but if look moved trace position and scale. It have stepped up 20dB.
It looks weird if do not know what happen there what can not see in video. Are there edited some things out from video just in this point or what happen.
I do not have SVA so I can not repeat this...



ETA:

Video screen shots

ETA2:

Finally after more analyzing video  these bit blurry screens it looks like it is ok.
Left scale after change from 20 to 30dB attenuator and small vertical adjust
left scale must be from top to down...   1, -9, -19, -29..... etc.  (not 1, 0, -10, etc...) So there is not bug in left side scale. Also if there is 0 it do not have - sign.
So this was wrong alarm.  |O :palm:

What you see is a product of fast touchscreen demonstration with NO clear defined intent. (like some old Dave video of fast turning of knobs)

With such a swipe of a finger up and down the display both Ref and Atten levels can be affected and Jason's actions show this well.
But, when a finger is placed on the sweep waveform and raised or lowered with clear intent only the Ref level will change.
hendorog and I have just explored this issue without any attempt to adjust touchscreen properties from factory default.
Until I explore how user touchscreen settings might affect what you see in Jason's video I cannot call it a bug, only fingers working faster than mind.


Not ideal I know for an SA but a wireless mouse and keyboard works just fine with SVA.

I have my SVA back now but lost my SSA to hendorog .......again.  :scared:

Yes but what ever user do with his fingers final steady result must not be wrong. Of course dsoing something fast there can be  some errors until  all is updated in screen but this is not like it, this error stay.
Now result is that noise trace is roughly 10dB too high if look left side scale numbers.
As can see. image 2  there is left side scale. 1 , 0, -10, -20, -30, -40*, -50, -60, -70, -80,  -90 
*Noise trace is here (around -40dBm)
Then left top corner there read Ref 1.0 dBm
How it is possible there is left side scale 0dBm to 1dBm one division when setup is 10dB/div. Least this is not ok.
It is wrong without any doubt.


It looks like all is ok IF left side scale is  1 , -9, -19, -29, -39, -49*, -59, -69, -79, -89, -99  (I do not have SVA so I can not look more deep)
ETA:When analyzing a little bit blurry video, pretty sure it is this.

Perhaps it is old FW ???  or is this issue still there?  So this is nice if we know it.

I know Jason is just demonstrating mouse and touch and keyboard. Not testing other things.

But when I look this video first time, immediately I see something what I did not expect with my experience and after then I replay it again and yes, noise level hop 20dB when attenuator change 10dB. 

(later look more carefully and find that if correct left side scale, it is ok)
After then I look left scale and ... oops ... how first top div can be 1dB when scale is 10dB  !

My suspect is that in this FW version what ever he use,  it looks like there is bug in left scale numbering.
It is nice to know if this is repaired in later FW-

I am going to go out on a limb here and say that it does show these values after the swipe.

I went back to the video and the 0's are more clearly 0's before the adjustment. After the adjustment they don't look as clear and so that makes me think that they are actually 9's.

Image attached shows two numbers. One from after change on the top, and before change on the bottom.
(These aren't from the same position in the grid, I just grabbed two which looked clear.)


I think top value is -19 and bottom value is -10

For those 'playing along at home', here's the only screenshot that shows some change in results after a 'bush' Cal done at frequency of interest and with a cheap 50 ohm BNC terminator and a homemade short.
Still pretty close but maybe just a little tweak of the feed point will get the impedance back to 50 ohms.

I don't think you are going to do much better as far as resonance and impedance matching go.
Now you need to move on to modeling the antenna to determine its gain/radiation pattern to ensure that all the energy is going the way you want it to, and not straight up in the air.

There is a bit of disagreement between the User Manual and the Datasheet.

The User Manual, on the subject of the tracking generator says:

For example, if the sweep is set to scan from 1 MHz to 10 MHz, the TG output frequency will change from 1 MHz to 10 MHz in coordinated steps with the sweep.

However, the Datasheet says:

Tracking Generator
Frequency range 5 MHz~1.5 GHz

Can someone confirm that the lowest frequency for the tracking generator is really 5MHz?
I can't see any good reason to limit it like that.

Yes it is wrong.

However deeper investigation reveals the datasheet error is most likely a typo. See reply #194

One can see where I've placed markers the guaranteed TG +3dB flatness is from 500 KHz (0.5 MHz) (marker #4). Marker #3 can be seen to be a little over 3dB down and I've placed it directly on a small red + (not caught/visible in screenshot) present on the sweep that apparently marks the start of the guaranteed sweep specification.

Problem solved in my mind, TG spec = 500 KHz -1.5 GHz.
I'll drop Siglent a memo to correct the datasheet.

What does the trace look like with the TG turned off?

In general for SAs, there isn't much point in putting a marker at 0Hz - you'll just get the LO bleed through which will show at an amplitude of its real value plus whatever attenuation is in use.  In fact, you don't want to look closer to 0Hz than beyond the skirt of the RBW filter in use.

You can get closer to 0Hz with a smaller RBW, but it doesn't look worthwhile for this purpose.  TG output seems to be getting down in the noise at around 25kHz.

The contention that the TG spec should be from 500kHz seems right to me.

You could probably use it down to 100kHz or so, but with the TG output at -15dBm and the noise at -50dBm, there's not going to be much dynamic range.

Siglent insist the datasheet TG spec of 5 MHz to 1.5 GHz is correct and they add this comment:
The frequency from 5MHz to 1.5GHz meets the specification of datasheet and the 9KHz to 5MHz (range) can not guarantee compliance with datasheet but it can be outputed.

As above it seems Normalize can compensate right down to ~9 KHz, with provisos of course.
Settings affect the full dynamic range where above screenshots were taken with a Pos Peak detection the range can be improved some using Average and an RBW down to 1 KHz without entering into inconveniently long sweep times.

If the Datasheet is correct, then the User Manual example needs to be corrected.

There is a lot misleading advertising around this product it seems.
Its advertised as an SA/VNA from 9kHz to 1.5GHz.

Except that ... its not a VNA unless you pay 50% more.
The VNA doesn't go down to anywhere near 9kHz, off by an order of magnitude
and the TG which is really a pretty important component of the SA only goes down to 5MHz.

I was saving my pennies to buy one, but I am becoming less and less enthusiastic.

I have been running john the ripper against the PW from the SDG2042X for 36 days solid now - at 214,000 tests per second.
That one is obviously either a tougher nut to crack, or they put random garbage in the shadow file ... always a possibility.

Which it is.
In SA mode when it is practice to Normalize, any sweep amplitude flatness error is corrected for. This is what Normalize does. The datasheet spec is for guaranteed TG flatness.

First post on eevblog.  Hate to start off on a down note but I came into some disposable funds and was looking hard at the SVA1015X when I came across this: https://groups.io/g/svna/message/78 (https://groups.io/g/svna/message/78)

Quote
VNA function has a 10MHz lower limit. Presumably this is due to the chip coupler, but rules out 40m and below for VNA.

The SVA1015X datasheet corroborates this: VNA frequency range is 10 MHz~1.5 GHz.

No VNA operation below 10 MHz?  I'm sorry but that is a major fail in my book.  As a ham and electronics hobbyist I'm looking to characterize filters, baluns, chokes and other devices at HF frequencies below 10 Mhz.  I realize that professional engineers today spend most of their time at frequencies several orders of magnitude higher, but even so they still deal with intermediate stages that are below 10 MHz.

Anyhow, that limit wasn't mentioned in Dave's excellent teardown/review and I didn't spot it in this thread so I thought I'd share it.

Welcome to the forum.

If you hadn't realized, that link and post was from our member hendorog that had my SVA1015X for a while for checks against his HP gear. We expect some more improvements to SVA however from replies I'd had from Siglent, no changes to datasheet specification.
One must be somewhat careful deciphering the datasheet for these as specs listed are for guaranteed accurate performance when the equipment can indeed operate outside those specs but with lesser accuracy.

Yep thats me.

That limitation is mentioned and discussed here. I initially assumed that it was just a first release software limitation which would be removed. Then someone correctly pointed out that it was likely due to the lower frequency limit of the coupler.

This might not be as big of an issue if and when the software is enhanced to support S parameter exporting to a PC. Then an external coupler and a couple of mixers could be used to create a simple transverter to cover that range. Possibly the SVA reference could be used as an LO for the transverter.

The other software enhancement which would make this simpler is an OSL calibration type on port #2 instead of just on port 1.

For the adventurous it could be done without the software enhancements, by feeding the transverter output back into port 1 via a second directional coupler.

I have played with this approach on a different device as a way of converting any spectrum analyzer into a VNA.
The SA input will always have some (unwanted) LO coming out, and so the idea is to take that unwanted LO, convert it in frequency so that it matches the input of the SA, amplify it and then bounce it off a DUT. Then feed it back into the input of the SA again. The downside for an SA is that there is no reference channel, unless a solid state switch is also added. The SVA has the switch and reference channel already.

Not an out of the box solution, but it is possible.

To be fair it's difficult to make a coupler that can work all the way from LF to UHF; you basically need a balun that covers that frequency range and preserves balun action.

I wouldn't bother because the accuracy will be spotty at best; keep in mind any phase drift introduced in the signal path will screw up the measurements, which is why in a proper VNA there is always a reference path. In my experience of designing VNAs the reference path must be identical to the reflected path and any mixing stages must be driven from the same LO for both paths (even two LO signals phase locked to the same clock isn't good enough), so having a transverter on the reflected path but not the reference path will really fuck up the measurements.

I don't think it's worth bothering trying to hack this because you can very easily build a much cheaper VNA that will actually be accurate; I can imagine for HF to VHF just some cheap clock gen chips plus a coupler using a cheap surface mount balun, mixers, and a stm32 with audio ADC will do fairly well. Actually that might be a good product idea.

Also I don't think any of the low cost VNAs can do SOL calibration on port 2, because they are all of the T/R type, meaning only port 1 has signal output capability. Designing a full two port VNA (and one with good port-to-port isolation) is HARD; not only do you have to have a port switch with 100dB isolation, you also have think about things like the RF signal leaking into the LO via the receive mixer and then into the other port's receiver mixer (you can't use two different LO synthesizers for the two ports for the aforementioned reasons). And to lay out everything on a board while keeping good isolation between the sig gen and the two ports, between the sig gen and the LO, between the two receivers, while keeping in mind the LO signal has to be routed to the two receivers. Only after almost a year of development did I manage to get all the details right and build a full two-port VNA with reasonable performance.

The 10MHz for the transverter can be taken from the reference output on the back of the SVA. No phase issues with that as its driving the LO already.
But I think you are correct, there will likely be an accuracy hit from amplitude differences between the reference path and the signal path. I'm don't know what the extent of that would be.

Port 2 of the SVA has an even more direct signal path to the ADC than Port 1 does. So with software support it would be quite possible to use that input in a cal or measurement same as Port 1 can.
Port 2 lacks a coupler obviously, we need an external coupler to get below 10MHz anyway.

I'm not talking about 100dB isolation here. Its just a simple cost effective way to make measurements below 10 MHz on an instrument which has this limitation.

Here is one for the N2PK for measuring higher frequencies. Its not rocket salad.

Agreed, for amateur use an LF limit of 10MHz does not make any sense.
When you look at other VNAs, the lower limit is normally around 100kHz (with bias tees) or close to 10kHz (without).
When you look at the VNAs from DG8SAQ or NP2PK its possible without major effort.
The record holder is a Keysight E5061B with a lower limit of 5Hz (also definitely without a coupler).
Why did Siglent do it this funny way ?

You need a coupler for the reflection measurements, and you need a reference for the reflection measurements to be complex, or they can't be used to calculate input and output impedances - which is a major reason to have a VNA in the first place.

In other words, given Z=Z0*(1+S11)/(1-S11) for a reference impedance Z0 (e.g 50Ω), if you use |S11| instead of S11 you get Z0*VSWR, not impedance.  If you plot the two curves for S11 = [0+0j, 1+1j], you get two very different results:

(http://www.rockgarden.net/download/eevblog/z_plot_cmplx.png)(http://www.rockgarden.net/download/eevblog/z_plot_real.png)

(Z0=50Ω; real on X axis, imaginary on Y axis; |Z| from complex S11 on the left, using |S11| on the right.)

Prospective customers are still finding out about them and their capabilities.......give it time.....this instrument fits a niche market of those that don't need a high BW SA and for which the VNA can be useful too.

BTW, for US buyers the Siglent shop has one on special:

Getting a frustrating OZ made Merlin garage door remote back to correct 339 MHz frequency. RF coax loop sniffer used.
Luckily it has a cap trimmer to do so but this remote unit is so old now the trimmer had to go for a swim in IPA before it would behave properly.  :phew:

I am pretty much convinced that the lower frequency limit in VNA mode is due to the directional coupler design. As I mentioned before, I am somewhat amazed that it actually works down to that frequency.

I don’t foresee any change other than a redesign, and probably significantly increased price to “fix” this.

If you want to roll your own directional coupler for lower frequencies, you could use it in SA mode and use the tracking generator. It isn’t a VNA when used like this, but for checking antenna SWR and filter frequency response it should be good enough for most ham purposes.

I bought one. It only arrived last week, so I haven’t had time to really play, but I did use the VNA to look at how my old 2m/70cm antenna is working (well, apparently). SWR and Smith chart views were good.

Also switched to SA with the antenna connected as input, restricted to 144 to 148 MHz and watched the signals appearing and disappearing. Better display of this than I get on my radio ... but so I would expect.

I was a little dissapointed at the low end coverage, but if you want a combined sa/VNA and all the other options going up to 1.5GHz, it is going to cost a lot more.

My biggest gripe is the cost of the options, and just how much of the functionality is an option.

Hi,

any update in TG and VNA low frequency ?
After such issues with the VNA and TG low frequencies, I´m asking my self if is better to go for to SSA3021 instead.
I lost the VNA function but the TG is much better.
Any ideas about that ?

The data sheet specs are what they are unfortunately but a SVA3kX model is coming.

Some addition of options can be had if you study here:

More then 2k hear in Europe, I presume.
I want to keep the value around 1,5k eur.

I’d be very surprised if the current free TG gets dropped from the SSA models, yes it was a option when they were first released but I strongly suspect due to the popularity of the SSA models it made sense for Siglent to include the most basic option TG free of charge and SVA models come with TG free at release.

As I’ve mentioned earlier SVA1015X has a larger trial time usage of 120hrs that is large enough to allow several projects to be completed before deciding on what options to purchase for your requirements.
SVA can do a lot of tasks, most that I’ve barely used and Dave in his tear down just quickly investigated.

All we know about the coming SVA3000X models is pictures from Electronica from a couple of months ago, see here:

"VNA mode: fasten the VNA sweep speed; expand the minimum span from 10M to 10 kHz"
The minimum span only, not sweep was reduced and in the previous 12a version firmware.
No changes have been made to existing data sheet specifications however some small functionality has been added along with bug fixes and some other improvements in version 13 firmware.

I don’t know any reason why it will be different to SSA models however how I got the options out of SVA was a bit different.  :-X
My SSA used the standard procedure.

Hi everyone.  I usually lurk here more than post, but I thought I'd share a odd behavior of my SVA1015X that's a bit confusing.

I've only recently acquired this unit, and I'm new to spectrum analyzers, so it's very possible this is user error, but I've been looking at reviews of the SSA3021 (as I haven't found too many of the SVA1015X), and those models don't seem to behave this way.

I've noticed that when the tracking generator is ON and NORMALIZE is also on, changing the CT, Start or Stop frequencies seems to cause the SA to rerun the NORMALIZE procedure, effectively cancelling out the current waveform.  I am able to consistently reproduce this behavior and I am hoping someone here can clarify where I made a mistake or maybe can confirm the issue.

My setup:

TG Output -> N/BNC converter -> BNC cable -> BNC/N converter -> SA Input

Here's the steps I used to reproduce:

1.  I reset the SA by pressing the Preset button.  Then I turn on the Tracking Generator by Pressing TG and then ON.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=621871)


2.  I turn on Normalization and set the Normal Ref Level to 20dB.  At this point, the trace on the screen is a line at 0dB.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=621877)


3.  I insert a 20dB attenuator inline, on the SA Input side.  The screen shows a line at -20dB.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=621883)


4.  I changed to the Frequency menu and change the Center Frequency to 500MHz.  The SA redraws the line at 0dB.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=621889)


5.  I try changing the CF to 750MHz (by typing 750Mhz on the keypad).  Screen still shows 0dB.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=621895)


6.  I try the Span menu and press the Full Span button.  Screen still shows 0dB.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=621901)


7.  I went back to the TG screen to verify that no settings have changed as a result of my testing
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=621907)

I have attached screen captures, but I haven't figured out how to insert them into the body of this post.  If I figure it out, I'll update this post.

Does anyone know if this is normal behavior for the SVA1015X?

Thanks

My setup:
.................
I checked this ^ with my SVA1015X and SSA3032X.
Yes, I see the same behavior and when using the higher BW SSA it became clear why.

When changing the CF in the SSA the Normalize is upset, that is it's not a perfectly flat line anymore and to correct this one needs to cycle Normalize to get a flat line again.
It would seem from these observations Siglent have the auto Normalize much better in the SVA while it could still be improved some for the SSA.... it's plainly apparent but takes only toggling Normalize to correct.
You can see the tiny Normalize errors in your screenshots after making the adjustment so I would still toggle Normalize to correct them after making any adjustments.

If not wanting to loose the previous sweep, I suggest you select View for Ref Trace in the TG menu and it will be frozen/locked before you make any further adjustments however you'll still have a live sweep to work with.

Post by: rmel on January 13, 2019, 10:49:25 am
Thanks for checking.

From my testing, toggling the normalize requires that I disconnect the DUT and short the cables together again.  If I don't do this, the SVA no longer shows a waveform for my DUT.  I only get straight line at 0dB.

I might be able to understand the reasoning why it would be preferable to require the normalization to be toggled, but having to disconnect the DUT and short the cables every time is a PITA.

In my opinion, it is a BUG.  It should not re-normalize after you change the CF or Start/Stop frequencies.  Anyway, the logical procedure sounds like to first set the CF or Start/Stop frequencies, then normalize, then insert the DUT and measure.

It does kind of seem that way. I would expect if you change some settings that change/effect the prior normalization it would just report that it is no longer normalized.

This is what I'd expect too but it's currently not the case so emails have been sent to look at this behavior so to address it or have the unit warn the user.
What do other SA's do ?

Based on the appearance of the noise in the screenshots it doesn't look to me to re-run the normalise procedure. If it was the line would be completely flat as tautech mentioned.

In fact it looks to be retaining the normalised data and using it for the reduced span, as the noise in the trace looks very similar to what it was before.
However, for some reason it is moving the trace up by 20dB. It could be that this is the real bug, perhaps something to do with the 20dB reference offset. Try again without that offset perhaps?

On my Signalhound, from memory any change to the sweep params will discard the normalised data. I think the HP 8753 VNA will 'try its best' to keep the calibration if you have interpolation turned on, but I will need to confirm that.

From a user perspective, it would be great if I didn't have to toggle the normalize for small shifts in frequency or span.  If I see a part of the screen I'd like to zoom into a bit, having to disconnect the DUT each time would be pretty inefficient as I search for the best CF or span.  Is this how it's done with other SA's?

Here's a video I found of a review for the SSA3032X where the author changes the span to zoom in without toggling normalize.  Being able to do that would be ideal, in my opinion.

It looks to me like the normalised data/calibration may be lost when he does that. The marker changes from -1.48 dB to somewhere around -3 dB when he changes the span.

No issue here, mine works properly and I suspect it's just that rmel didn't mentioned he'd removed the 20 dB attenuation.

I retried my test without the 20dB offset, and unfortunately, that didn't make a difference.  Also, in my first post, I
didn't remove the 20dB offset.  The last photo in the sequence shows that it's still there.

To give a clearer example of what's happening, I thought I'd use a different DUT (a simple RC circuit) that produces something other than a straight line to show
what's happening on my screen.

My setup:

TG -> BNC cable -> DUT -> BNC cable SVA Input

Steps:

1.  Preset -> Frequency -> CF -> 20MHz.  TG -> ON
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=622861)


2.  I connected the DUT with Normalize OFF, just to see what the signal looks like without it.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=622867)



3.  Removed DUT and shorted the cables again, then: TG -> Normalize ON
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=622873)



4.  Connected DUT
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=622879)



5.  Frequency -> CF 19MHz.  You can see that the output is 0dB.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=622885)



At this point, the behavior gets weirder, as when I turn the knob to changed the CF, the screen flashes the expected
waveform before going back to a "straight" line.  I created a video of this here:

Ah nice - now I think I know what is happening :)

The normalised data is still being applied. The problem is that by moving the CF around you are causing the instrument to not find a frequency match in its stored list of normalised data points. When you move the CF continuously like in your video, then sometimes it does match and so you get the expected result.

So, I hypothesize that some settings of CF/Start/Stop will at least appear to work correctly and some will not. :)

Unfortunately for me, I haven't been able to find any frequency where my signal is displayed correctly.   Whether I enter a frequency directly on the keypad or if I turn the knob slowly, it only shows me the correct waveform for a very brief time.

Yes, well you normally wouldn't use a SA like that, instead you'd set some reference level appropriately near mid display.

Jump over into the SSA3kX thread and practice mimicking some of the simple usage examples from members like rf-loop. When I got my SSA3032X, there is where I learnt basic SA use as like you I'd never had a SA before let alone used one.

Do you have a sig gen to practice with ? (be careful to keep inputs to safe levels)
Once you have the basics venture into work with reflection bridges and directional couplers and then explore the VNA world that awaits you.
Little steps.  ;)

Watching this from Shahriar might help too:

Yep, well watch it again from 37.20 where Shahriar explains that changing settings will impact the normalization and he recommends once the settings are as you want then to re normalize for accurate results.

Title: Reference Offset and Trace View
Post by: rmel on January 20, 2019, 08:26:53 am
Ok, here's another behavior that seems weird to me.

Can someone tell me what I did wrong here?

Here's what I did:

I am feeding a square wave at 30 MHz through a 20 dB attenuator to the SA.

Preset -> Amplitude -> Reference Offset -> 20dB
Peak -> Peak table on
Trace -> View

Then the peak values in the Peak Table seem to go nuts and the waveform disappears.

Here's a video I captured:

Sorry but using two *10 scope probes to "demo measure" with the SVA1015X's VNA function in an unpowered CB radio corpse is, well, a little "unresultful"   :palm:
This RF stuff definitely isn't Defpom's business, clicking through the menus isn't what really helps someone seriously interested in a purchase. Regarding things one doesn't feel "at home" with, better do yourself a favor and let others who are more into it do this job.
Watching this clip is a waste of time, and probably producing it was even more so for Defpom. He's got much better reviews in his channel than this one...

Cheers and no offense intended  :phew:

What I was trying to demonstrate was the filtering effects of the tuned circuits in the RF section of the radio, and the ability to see that on the Siglent, no I wasn't trying to obtain accurate and true measurements, and at no time did I say that was what I was doing.

My reviews are done in a way to try and replicate how a new user would find the gear, something that is easy enough to capture as sometimes (such as in this case) I am not an expert in its usage having only limited experience with the particular item.

Hello,

I have some trouble with UHF RFID developpement and it is maybe the time for me to buy a this kind of tool.

Almost All Siglent instruments have been hacked.
Is this the case also for this one ?

The start price is pretty decent but It will be nice to have EMI precompliance, Advanced Measurement Kit and VNA too  >:D

I just posted a video showing the power consumption, power factor, and line current waveforms for the SVA1015X spectrum/vector network analyzer.

I also demonstrate a consistent hard crash mode when the VNA mode is turned on while the preamp is on in the spectrum analyzer mode.  This crash requires a power cycling to reset.

If you missed it I also posted a review of the vector network analyzer mode a few weeks ago

@graybeard

IIRC it is possible to use custom cal kit in the VNA mode of the SVA - for a competent unix user.

The cal kit definition is stored in a file on the file system, and could be backed up and modified to suit another cal kit.

Also IIRC the definitions are stored in a file as mag/phase data, so any standard which one has measurement data for can be used as a cal standard.
IMHO this is a more comprehensive method than using the traditional Cx/Lx model which is what I think you are proposing. I do agree Siglent should implement custom cal kits in the UI.

The gain and phase information is the best method, especially at much higher frequencies where a lumped model is inadequate.  However in the frequency range of the SVA1015x lumped models work well.

Looks like a very big jump in the UI and features!

Is there s-file export yet? Looking at the video it appears to be a csv data dump, but not in a standard s1p format. Is that correct?
Is there a plan to implement Enhanced Response calibration type?

With Enhanced Response calibration and a good attenuator, to improve load match, I believe you can get results almost as good as a full 2 port calibration.

The data export is only CSV, there is no S1P file generated.
   
If I wanted a S1P file I would just set up an EXCEL or Libre Office template to do the translation.

Yes of course. But why not? It is the standard format if you want to integrate the data into any other software.

But it certainly is nice they have now made some progress on the basic stuff thanks to your prodding.

Update.

Based on this post:
Here's a snapshot of the Siglent showcase at Electronica 2018.

The SVA3032X prototype analyzes a 16QAM signal produced by the new SSG3032X-IQE, which in turn is using an SDG6000X with I/Q option as the modulation source.

The display of the SVA3032X has been brought to the big monitor using the internal webserver and a notebook computer hidden under the counter ;)
(https://www.eevblog.com/forum/testgear/new-siglent-products-sds2000x-e-sva3032x-and-a-dc-load/?action=dlattach;attach=579734)
We thought a SVA3032X was coming however recently the Chinese website has been updated to indicate a SVA1032X is actually coming.

Noticeable improvements:
Vector network analysis mode with frequencies ranging from a minimum of 100 kHz to a maximum of 3.2 GHz.
DANL -161 dBm/Hz

Notice:
This firmware must be upgraded from V2.1.1.1.12a or later. If your SVA1015X has an earlier version, please update to V2.1.1.1.12a first and then proceed to update to the latest version.

New Functionality:
 Add a spectrum view, marker for MA Mode
 Add mode couple for center frequency
 Add system message

Improvements:
 Start Frequency in Harmonic measurement in AMK options to 1 Hz
Start Frequency in VNA Mode to 100 kHz
 Optimize .sta file, trace interpolation for VNA Mode
 Optimize PSK/QAM clock sync ability for MA Mode

Solved Issues:
 Fixed AVG, Math bug for VNA Mode

I will try out the new firmware in a couple of weeks since I an currently traveling. 

I suspect there is loss of S11 dynamic range as the frequency goes  below 10 MHz, but it is still a great feature to have.

I hope by mode coupling of the center frequency you mean that it can transfer the center frequency to the modulation analysis modes.  I asked for that,

Things I would still like to see:

The firmware looks like it was removed from the website, at least the north american website as far as i can find.  That is a MAJOR relief for me (amateur radio operator that builds a lot of his own stuff) as i was having to track down something else sub 2k because this one couldn't go that low.

It goes down to 100 KHz, not 10 KHz. The useful low end for S11 is around 1 MHz.  Averaging does not help because the calibration sweeps cannot be averaged and the calibration is very noisy at low frequencies.  Hopefully they add calibration averaging to the next firmware release since it could help improve the performance both at low frequency and when calibrating through attenuators.

I have not tried the S21 yet, but I suspect it will work great down to 100 KHz since it does not rely on a directional coupler.  I will play with it more and post my results in the next few weeks.

I found the firmware on the English section of the Chinese web site siglent.com

Great!  Glad to see that someone has confirmed they grabbed a firmware that allows this.  My mistake on the 10Khz, i see now it was 100Khz.  Not a big deal as about 3.5Mhz will be the lowest i need in most cases. 

Out of curiosity i called the NA office on Ohio to ask about it.  The guy i spoke to seemed reserved about discussing the drop in frequency and said that "nothing official has been released" and that he could not speculate on it (nor a speculation on a 1032x).  I suspect it was possibly a firmware release that had that feature in it a bit prematurely.  I finally found an English copy of the release notes on the non-na website but it did not mention that change/upgrade to the VNA low side.  I will see if i can find the Chinese version and see if its in there. 

He did mention they did some website changes this past weekend, which may explain the dead firmware link on the NA website.

I'm ready to order at this point, just trying to make sure i can get that firmware version and it actually works. 

Now we just needs some hacks for the 1015x   :D

I was not happy with the VNA option when I first got it, but firmware updates have turned it into a highly useful tool.  I am very happy I bought it, even with original 10 M Hz limitation.

Thanks!  After checking, there is no mention in this for the lower VNA range either.  I wonder if there was some sort of issue with this.

Chinese release notes (courtesy of google translate):
This firmware can only be upgraded from V1.2.1.1.12a and later. If your SVA1015X spectrum analyzer is an early firmware version, please upgrade to V1.2.1.1.12a and continue with this version.
New features:
 Add Mode Couple function
 System log
optimization:
 Optimize UI refresh and response
 Optimized .na file for VNA mode
 Optimized VNA spurs
 AM/FM adds spectrogram
 MA mode adds Marker
 Enhanced demodulation stability of PSK/QAM
solved problem:
 VNA mode avg, math is not good
 Other bugs

The only one im not sure about is the .na file updates.  Not sure what that does/adds other than possibly better file management (for actively writing logs while testing?).

From the guys attitude on the phone i feel as though he knows about the lower range disapearing and figures that it will be back, but if he says it he'll be liable for it if they chose to never release it again.  Either that, or he has about as much communication from the home company as we do lol!

I'll probably still pull the trigger. Though, it would be nice to have the lower VNA range so i could finally get rid of my antenna analyzer rather than having to carry two pieces of equipment.

The .na trace is actually .sta trace in the english release notes. That is just an improvement in saving of the trace to a file.

Here is a through measurement of a 137MHz filter. The markers are at about 2MHz.
For this DUT at least it works well down to 2MHz or even below.

The measurement of S11 down below about 3MHz is where you see the limitations of the coupler.

A good warm up time helps. It is using maths to compensate for the coupler and so the more stable you can make it the better the results will be.

Title: Re: Siglent SVA1015X 1.5GHz Spectrum & Vector Network Analyzer
Post by: graybeard on August 14, 2019, 08:08:14 pm
The dynamic range of S11 is reduced as frequency decreases, so the specs would need to be adjusted to show it.   However my initial tests show S11 is usable (~30dB of range) down to 2MHz, and is good enough for a ham to check their 80m antenna,and would ev en be usable for the 160m band.

Having tried this, I would like to see Siglent lower the usable frequency range down to at least 1MHz from the specified 10 MHz.  It is usable enough for many situations and would widen the market for this very nice instrument.

The firmware link was broken after I posted about the upgrade so I have replaced it with a working link to the Ohio webpage. The Release notes posted were copied and pasted directly from the SVA release notes file, they are the official notes !

I can further inform you the reduction in VNA mode form 10 MHz to 100 KHz was a bonus from the development of the coming 3.2 GHz SVA.
hendorog has my SVA so watch for some advanced use screen shots using the new firmware when he gets the chance.

Yep, and while options for SVA have 120hrs free trial times they do eventually expire.
A customer contacted me a few days back on purchasing AMK for his SSA3021X as there were some features that he wanted to regain.
The pricing of options is such they are not cheap but there is a simple remedy if you can be tethered to a PC, that is using the free EasySpectrum software from the Siglent websites.
It seems all the AMK features are included and you can get the same info from the PC display and capture screenshots too if you desire.
Not as nice as using the instrument stand alone but nevertheless option features are still usable.

SVA1015X, all the SA options should also work fine in EasySpectrum but at this time I can't confirm the VNA option does until I get my demo unit back and try it.
In a few days I will report on this...............

I imply that the tracking gen starts at 100KHz, right? If so I guess that for getting the response of a filter in even lower frequencies I could still use an external sweeping generator and the SVA configured in max peak mode?

According to the datasheet the tracking generator starts at 100kHz for both the SVA and SSA.
Considering the system architecture, this seems plausible.

Yes, with an external sweep generator and max hold you can get a frequency response graph, although this method is slower and the signal source needs to have low harmonics in order to give accurate results.

With release of the 3.2 GHz SVA1032X there is a pricing structure change for it and SVA1015X.
Both will feature the VNA option as standard fare however at an increased base price.

SVA1032X features a slightly lower DANL of -161 dBm/Hz that aligns with SSA3000X models and in addition better amplitude accuracy of <0.7 dB

Hello today is the launch day (Europe) for SVA1032X and SSA3000X Plus.
SVA1015X and SVA1032X have VNA standard, SVA1015X has a new price.
SVA1015X VNA BW 10MHz - 1.5GHz
SVA1032X VNA BW 100kHz - 3.2GHz
To make everything as clear as possible we have created a table that compares the various models of Siglent spectrum analyzer and vector network analyzer. The table is large and looks good on PC and Tablet, on SmartPhone you may have display problems.
here is the link of the table, I also attach an image of it.

Interesting to see what's Siglent's official word on SVA1015X specs.

When they launched it the lowest frequency (as quoted on the datasheet) was 10 MHz, but now it can be usable (at least for rough "antenna analysis, just show me the VSWR/RL") from 3 - 5 MHz.

I tried it with a 7 MHz loop and the results were certainly useful.

My HP RF generator (8642B) starting frequency in data sheets start from 100kHz... also front panel nameplate it start 100kHz. Specifgications starts from 100kHz.   In real life it starts from much lower freg. Usable from some kHz. Signal is even quite nice after 10kHz.  But HP do not guarantee any specifications under 100kHz. HP think: If user use it under this (data sheet specs) 100kHz, it is users head ache if it meet user needs or not. Just, use it if it pass needs but don't complain if it doesn't work "right". There is no promise, only unknown, unspecified. 
And this same is with many instruments.

I believe here with SVA is same. But no need complain and grumble if it do not have its normal performance and accuracy when working outside from specificied range. ;)

Correct and as a result of SVA1032X development it was decided to lower the SVA1015X VNA BW whereas before anything below 10 MHz was not even available to the user.
What we checked way down in frequencies certainly was usable and even more so when lots of averaging was applied.

Interesting....

I upgraded my SVA1015X to 2.2.1.2.2 when I saw it was available.
Never saw any mention of extended VNA range though.
Got an email from Siglent talking about extended range and the new kit so started looking closer, and came to this thread (since this is where you come if you really want to know :-) ).

Switched into VNA mode and tried to set a frequency below 10MHz -- nope.

Hmmm....

Finally looked at the provided links, and saw that the firmware was for SVA1000X.
I had been using the firmware for SVA1015X (since that is what I have).

Tried the 1000X  firmware ... load, re-boot, switch to VNA and lowest frequency is now 100khz!

Slightly annoying that there are two variants on the firmware with the same number that behave differently!

ETA: After a few minutes playing ... I am now MUCH happier with this device. Not covering the lower frequency ham bands was a bit of a pain (but an acceptable one given the other functionality it bought). That niggle has now gone.

I have to say that I am a bit amazed that they get this sort of performance out of those directional couplers though...

OK, Philip.

I think things are not as you said. It's this last version that enabled the new freqs.

And there is no FW for 1015 and another for 1000. It's all the same.

I think they just started renaming it 1015 because of the coming 3.2GHz model.

You made me go back and look at the two firmware versions.
Looks like you are right, the 1015.X version I had is 2.2.1.2.1
The new one is 2.2.1.2.2

That explains it. I don't remember where I picked up the .1 version from, but as I remember, it was labeled as the latest release, and this was towards the end of August...

Please note SVA1015X datasheet specs have not changed and are still listed as 10 MHz in VNA mode and as you  say we are now able to use VNA mode below 10 MHz right down to 100 KHz which is outside guaranteed accuracy however other users have reported good results down to 1-3 MHz.

Yes - you can see how they did this: The signal is very noisy (which is to be expected from those small directional couplers) so they just average multiple measurements. Not ideal, but at least it makes measurements possible. Specs are undoubtedly reduced below 10MHz, but so far, I think good enough for typical HAM use.

Undoubtedly the coupler is not great down below 3MHz or so. It is well out of its spec'd range. However that is compensated (i.e. hidden from view) by the inbuilt SOL calibration in the device, so you see that as noise on the trace. Other VNA's don't have a built in calibration and on them you can easily see the basic performance of the coupler just by attaching a 50 ohm load.

And of course you can do your own cal to improve it further. And when you do a cal, the magic of the error correction maths makes it a perfect coupler again!

However, when the coupler is operating in this low frequency region where its directivity is poor, what is observed is the noise and also measurement drift increase. The error correction maths amplifies the directivity which is great, but it also amplifies all of bad stuff, like noise and drift, which is bad.

So we see more noise, and the device becomes more sensitive to things like temperature changes. So turning on averaging, having a good warm up and a stable environment help. Doing the calibration and the measurements quickly also matters more in that region.

For HAM use, having the capability to do the measurement is generally more important than the convenience.
With that in mind, there is the option of using an external coupler between port 1 and 2, save the sweeps, and do the calibration on a PC. I am keen for Siglent to support OSL calibrations on Port 2 at some stage to make this a bit easier.

Another point which was raised by member graybeard is that calibration standard sweeps cannot currently be averaged on the device. The SVA just does one sweep and thats it. However if you do the error correction on a PC then you can use averaged sweeps of the calibration standards and then apply the error correction to averaged sweeps of the devices. Obviously that will take longer though, and so there will be a trade-off in drift to get the benefit of reduced noise :)

Is the hardware of the different bandwidth models the same? Or put differently may we expect a hack which would upgrade the lower bandwidth model into a higher bandwidth one?

Dear RF gurus!

For my hobby project (Zynq FPGA+ AD/DA + synthesizers,mixers, amplifiers, passives,antennas) I would like to buy either a: SVA1032X or a R&S FPC1500
Since my project is quite general I need all the T&M features I can get and these models offer a lot of them.  SVA1032X has QAM demodulation feature therefore I tend to put my vote on that one, but I have a serious concern. When Shahriar reviewed the instrument he performed QAM demodulation measurements on a saturated amplifier (see attached picture). To me these results make no sense.
When the amplifier gets saturated the constellation points start to move OUTWARDS instead of INWARDS.
It looks like the I and Q components become larger then what they are during non compression. For me this is counter intuitive. I thought the low energy symbols remain (more or less) intact and the high energy symbols at the perimeter of the constellation diagram can't reach their nominal location so their distance from the origin is smaller then during non-compression.
Please tell me why did the instrument displayed what it displayed!

I had bad experience with R&S high end devices in the past. My previous employer bought an FSW85 (1Hz to 85GHz) flagship signal analyzer for hundreds of thousands of euros and some of its software features were so buggy that the usability of the instrument was questionable. So  simply stick to the European quality dogma is not going to help me to make my decision neither. My be there are more folks out there buying an FPC1500 then an FSW85 R&S gets more feedback and has a more stable, bug free firmware then for FSW85. Not like they rushed to fix those bugs I reported them.
So guys what do you think? Which instrument is better for general DIY RF projects?Most likely this will be the only real instrument I buy in my lifetime or at least in the next twenty years so I would like to make the most out of my money.
Have a nice day!

Welcome to the forum Kolos91.

FYI there were a couple of issues Shahriar found when doing the video that have since been addressed by Siglent although this new FW version fix is yet to be publicly released. Although I have a copy of this new FW I don't have release notes but I was told by the product manager they were minor/simple fixes. Maybe they were for the QAM sorry I don't know.

Sorry I don't have my SVA units to check your as they are with a beta tester for study of the beta and public release SVA1015X firmware but there are a few members with these units that might give you answers.

For readers the question was for the QAM examples at 44.20:

Welcome to the forum!

I believe that a strong point in Siglents' favour is that they have been very receptive to feedback and are actively developing these products.

There are features which have been requested here which have been implemented and bugs reported which have been fixed. There are more improvements coming too.

My interest has been mainly in the VNA feature, and I've seen that feature improve radically, with input from several members here and others.

Actually the high level part (at the four corners, often normalized as 1) of the signal are indeed 'INWARDS'  to those LOW LEVEL PART in the center.

So your question is: why the signal looks 'OUTWARDS' to the reference red dot constellation?
I think the reference red dot constellation is a ideal normalization, while the measured signals are normalized to its RMS average power, which is amplified to saturation (comprssed), so the normalization becomes large?
Sounds logical? :palm:

Thank you very much!

You explanation perfectly aligns with the measurement results so I think I will go on and buy an SVA1032X :)
Although if symbols were normalized the opposite way it would be better, but perhaps that only bugs me.

Transferred from another thread:
Just got my SVA1032X and getting familiar with it.  I have a few questions and don't know if this thread is the right place but here goes:

1) Easyspectrum does not give any control over the VNA (at least not by USB).  Any future plans to provide this remote function?
2) Is there any way to directly save to a PC screen snapshots in VNA mode?  I know I can save png to the SVA1032x internal memory and then copy it to my PC but would be much more functional to control directly to a PC
3) Using Preset and going to VNA the number of data points defaults to 201.  This leads to some very choppy Smith chart graphs.  To get a really smooth Smith plot you need 500-700 data points.  Whats the downside to always using more data points routinely?
4) I have seen screen shots of the SVA1015x serial number and it begins with SVA, I was curious of the significance, if any, of my SVA1032x serial number starting with SSA3?

thanks in advance
Jerry NY2KW
1) Hope so, yes just checked and Mode is not available in V6. :(
2) Yes using the internal webserver and a LAN connection. There's a dedicated screenshot button that auto saves to your PC browsers download folder.
3) Simply, sweep speed is the penalty especially with wide frequency sweeps. Narrow the sweep to just cover the frequency of interest and it's super fast again and accuracy is enhanced with more data points.
4)That doesn't sound right....like it has the incorrect firmware installed or something.  :-//
Latest version is 2.2.1.2.5, what is your SVA1032X running ?

FYI, the attached screenshot showing Sys Info was grabbed via the webserver straight to my PC.

"SSA3P" is a S/N from a SSA3000X+.

But, currently, it seems Siglent is mixing the SSA and SVA S/Ns on both equipments.

Maybe because they all use the same FW...  :-//

So far it seems to.  I am a little disappointed how they implemented VNA User Calibration.  It lets you enter SOL delays but no option to put in a precision load value or the inductance or capacitance of the calibration standard being used.  I use Rosenberger calibration SMA sets as they are quite good and very reasonable cost.  Each set has individual calibration specs for each component of a SOLT calibration - Delay, R, L, C values for the Short, Open and Load.  Also wish they would implement a full 2-port calibration in firmware/memory the way others have even if it means swapping direction manually, at least all 4 S-parameters could be calibrated and then displayed.

You may already be aware but using external software is the  best way to get full control over the cal - and the models used for the standards.

It would be better if it was built in of course but at least it is possible now using scikit rf for example.

Perhaps it will be added this year. Many improvements to the vna mode were made in the last year.

Before buying, I read the manual but it was so brief on VNA module that I made the (poor) assumption that it would provide functionality similar to so many stand-alone PC interfaced VNA's that sell for less than $600.  For example I have SDR-Kits VNWA and it is incredibly robust and rich in features.  I bought the SVA1032x to get away, as much as possible, from being tethered to a PC.  I am not an EE but an advanced hobbyist and I am probably over-reaching on my 'routine' needs so I will hope that Siglent will continue to offer VNA firmware enhancements.

Thanks, Not familiar with Python but I do some C programming so open to learning Python basics.  I downloaded latest Windows Python then Anaconda and then installed the scikit rf module.  I went through the early examples including the plots - very cool!  It says scikit rf only supports a few VNA s as virtual instruments.  Next steps for me is to learn how to set up my calibrations and load SVA1032X data for manipulations in scikit rf.   Too bad there isn't a scikit rf GUI interface to simply things... I rather be using the SVA1032x than getting on the scikit rf learning curve.

There kind-of is a basic IDE for it, in the form of Jyputer notebook. Its been a while, but I think you will already have that installed due to using Anaconda.
It all takes a bit of time and effort to get your head around, but it does help being able to see the results quickly.

I wrote some docs for myself here:
https://github.com/hendorog/SVA1015X

If you store your code on GitHub, then the Jyputer notebook is rendered nicely and you can see the results just like in the scikit docs.
I did some tests here using a faked short measurement, don't read anything into the results as I was just messing around.
https://github.com/hendorog/SVA1015X/blob/master/docs/SDR%20Cal%20Test1.ipynb

I keep meaning to write a driver for the SVA, but haven't done so yet. The above data was extracted manually, which was a pain.

I scanned through your code. Looks like fun.   What is the file format for your standards that you are reading in?  For example, the file "data/ideals/KirkbySN0092" ?

I see there is a VI file that Siglent provides.  I know even less about Labview, etc but wounder if the Siglent VI file could be easily modified for use in scikit-rf?

I'm not sure - I don't know much about Labview either and don't have any desire to learn it anymore :)
Regardless, there is a good doc on the SVA remote SCPI API so you could just use that instead of reverse engineering the VI.

The files are touchstone format (blah.S1P), which is a standard format for exporting/importing VNA data. To create those from the SVA, I think I just exported mag + phase into a csv and then massaged it by hand using a text editor.

The cal kit I have, from Dr Kirkby, came with its own touchstone files which describe the standards. I use that method instead of the C0, C1, C2 etc model, as it is easier. It's one less approximation so should be more accurate. The 'ideals/SN0092' directory contains these files - i.e. the ones which came with the cal kit.

Of course with the Rosenberger cal you don't get the touchstone files, but you could theoretically create one which reflects the values they provide, or alternatively you could get the kit measured on a properly calibrated VNA and export them.

I have the Rosenberger kit too, and I must have swept them at the same time. (Note that these measurements are uncorrected, and they need to be corrected using the scikit cal before they mean anything)

This isn't working for me on my SVA1032X w/ V2.2.1.2.5.

I loaded SVA1032X_telnet.ADS onto a FAT32-formatted thumb drive (one which I've been able to save PNGs onto from the unit) and put it in. I went to System, System Info, Firmware Update, selected SVA1032X_telnet.ADS, and selected "Open/Load". I selected "Enter" on the warning about rebooting and stuff. It went into the "Upgrading now, please wait..." screen and stays there.
 
I then tried to run "telnet (ip address here) 10101" and got a "connection refused". I used nmap to map the ports on the unit and there is no new port open. The only open TCP ports are 21, 80, 111, 864, 5024, 5025, and 5900.

Am I missing any steps?

It seems not. We need another member to test.

You tried the connection while the SVA remains in "upgrading..." mode?

Yeah, multiple times :-/ No luck so far. I don't lose connectivity to the device, it just goes into the "ugprading..." mode and nothing happens, no matter how long I wait

Hi, I've been lurking arownd - had to chime-in to let you know that the file SSA3000X_Plus_telnet.ADS created on Saturday, ‎7 ‎December ‎2019, ‏‎10:05:34 AM does indeed boot-up Telnet without need for login  :)

Thank You for this TV-84

I was brave enough to 'try' on a new ssa3021x plus - did the appropriate homework;-

1. read all of the relevant forum posts
2. did nand backup
3. got latest sva1032x firmware
4. was about to flash
5. got your 'hint' re: product ID
6. now  |O to figure out how to change the firmware file to match

Keep up your great contributions - many would be lost without them  ;)

In general on the SVA you can't turn off the factory cal.

Speculation, but I think on recent FW you do get a glimpse of the native performance as you do an OSL cal. It shows very different traces as you step through Open, short and load than what we normally see.

A recent afternoon with hendorog, inspecting his Covid lockdown lab rebuild  :o and investigations of SVA's and Cal kits............my own 4.5 GHz SMA F603FE Cal kit coming in July from Siglent:
https://siglentna.com/product/sma-type-vna-calibration-kit/ (https://siglentna.com/product/sma-type-vna-calibration-kit/)

We wanted 2 good calibrations to save with my SVA1032X while good and warm, one on Port 1 and another after an N-SMA adaptor from Siglents UKitSSA3X Utility Kit:
https://siglentna.com/product/ukitssa3x-utility-kit/ (https://siglentna.com/product/ukitssa3x-utility-kit/)

The calibrations done were the normal SOL and each was saved into the file system where they can be selected and reapplied at will.
Cal kits were a SMA Kirby (7 GHz) and 18 GHz rated N type....didn't record the brand.  |O

Shot of the Calibration Save/Load file manager and menus.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000412)

A saved calibration is a Correction file and we need select, load and apply it for it to be of any use.
Once turned ON, indication the correction has been applied is flagged on the upper left of the display as COR.

Factory Cal

Correction added
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000394)

But Corrections need be applied to the right setup and as some example, this is the Kirby SMA correction on just an open N port 1 whereas it's intended to be used with an N-SMA adaptor and shows a massive difference to the previous screenshot.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000396)

The same sweep with an open N port instead of with a N-SMA adaptor but in Smith chart mode.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000414)

hendorog taught me to work with Log Mag/Return Loss mode rather than a Smith chart until you have a Cal sorted as more detail is available over the full sweep.
As some example of this here is a quite good 50 ohm load hendorog gave me a while back in Log Mag and Smith chart modes.
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000398)
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000400)
Log Mag looks awful but some of what we see is system noise and applying some averaging tidys the trace up some.

I also came home with a spare NanoVNA Short and Open from hendorog so curiously swept them as to how they might align to the Kirby Cal in the SVA and as can be seen below their Short is an absolute POS !  :horse:
(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000402)


Next I had a look at a 51 Ohm 0805 SMD resistor soldered onto a SMD bulkhead fitting that are very useful for component tests.
Log Mag looks pretty ordinary and the Smith chart too.

(https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/?action=dlattach;attach=1000408)


A few of these are handy to have and just scalpel the dielectric short and solder on components to be tested.

I'm suspecting you can't turn off factory cal because the raw directivity of the coupler isn't very good and they don't want you to see that ;)

I also see significant trace noise around 3GHz, it looks just like the nanovna V2. That is because it doesn't have a simultaneous reference receiver and can not cancel out synthesizer phase noise.

Don't bother comparing the original Nano to this, look at the V2 instead which has far better calibration standards and the VNA itself performs basically the same as the SVA.

All SVAs and the nano V2 currently are hampered by the magnetics based coupler. It performs poorly at lower and upper frequency extremes. I'm experimenting with balun-less active reflectometer designs that can potentially give you decent directivity from DC to 6GHz. Siglent has some catching up to do.

That is not true for _all_ SVA's.

The one on my bench has at least 30 dB effective directivity or below from 100kHz to 7.5GHz with no user calibration from power on.
This is simply determined by turning it on and attaching a good N load to the port.

I expect/believe there is a factory cal in there, but that doesn't matter. I have no knowledge of what is inside the box - I haven't opened it - but I assume it is some sort of SMD bridge + balun similar to the other units.

Not knocking what you are doing of course, it will be good to see your work in a new version of the nano.

Yes the factory cal (and ecal in the nano v2) hides the true directivity of the coupler. If the raw directivity is low, for example at very low frequencies where the balun is ineffective, the software has to subtract all the forward leakage and the result is more noise after calibration. The SVA series are architecturally very similar to the nano v2, which uses the same kind of coupler and the same method of obtaining the reference signal without an actual reference path (by using an RF switch before port 1 to short it out). I believe siglent has a custom ordered balun that can work up to 7.5GHz, but I'd be surprised if they can get 10dB raw directivity at 7GHz from that. I'd like to see the mentioned raw graphs during user cal.

Of course - the point I was making was that directivity out of the box is still better than 30dB even at power on (time of worst drift) and with the default cal. So for the class of instrument the raw directivity is high enough for good performance. It is after all a multi-purpose unit.

If you scroll up you can see the raw signal without any calibration from the SVA1032X platform (hacked SSA, they use the same hardware, but since hacked i have no factory cals :P)

It is not possible to import s1p files - in the current firmware. However, there are two workarounds:
* Adjust the delay parameter in the User cal kit setting to minimise the error.
* Export sweep data to a PC and use scikit-rf to do the calibration instead.

Maybe? Doubtful though..

1 this community puts out valuable feedback
2 the amount of affected units is tiny and they can reject warranty at will still over them

Business sales more than likely remain unaffected.. cant exactly send them out for calibration

Now if for some reason it's cutting into their business.. yeah you will instantly see a patch


Further they have never really done anything to stop people modifying their instruments on the whole

Hello,

I'm new on this thread as a user of my VNA from Siglent.

I just bought the SVA1032X and got strange behavior of it. The device shows some noisy signal but does not measure anything nor generate a signal on tracking output...

Did anyone experience a similar problem with it? This is the fresh new device, with SW 2.2.1.2.5.

I thought there is a need for some initial password, but after a call to the seller, he confirmed not.

Thanks for any suggestions on that, before launching the official warranty return..

Welcome to the forum.

TG is fulltime enabled on all Siglent SVA/SSA's and available as permanent so you just need press the TG button to turn it ON. bring up the TG menu and select ON. See screenshots below.
Try pressing the Preset button to return it to factory default where it will return to Spectrum analyser mode and TG should be available.

Thanks tautech for the prompt reply.

The point is that a tracking generator activates in a menu, but nothing is physically existing on the port 1 output. Also, the spectrum analyzer function is not operating - driving port 2 from the external signal source does not change observed background noise. Similarly like shorting ports together - see picture below.

The Preset button, restart or factory reset from the system menu does not change device behavior.

Tomorrow I will send the unit for seller's inspection if nothing discovered during a day.

The first screenshot is straight after a Preset which returns factory settings and full span, 10dB/div etc.
Do you see the same ?

Screenshot 2 is with TG port connected to RF in and TG levels shown on the trace.
Do you not see this ?

You can post screenshots easily here, just add them into Attachments when you post.

The first screen is exactly same as your after Preset.

The second is after TG activation with shorted ports - unfortunately no change in a trace.

I use original cables ordered together with an analyzer - they are fine, just tested on a parallel instrument.

How do you manage so much time on the forum? You genuinely attempt to answer virtually any question relating to a scopes/sa/vna/sg/fg/dmm's etc even when they are not directly Siglent related and yet time to find the time to run a fully fledged  electrical distribution business as well?

I am amazed at your stamina, sheer number of posts on here, and how you are willing to 'help out' any Siglent query even when its' not related to you in any way?

To quote Gene Hackman 'Ballsy little bastard'

Your ability to make firmware happen in such short spaces of time is frightening efficient (this is a good thing) though to make this happen you must have some real clout and direct line into the factory almost like Ronnie Ray-gun's hot phone line to the Kremlin.

I have been employed over the years in some serious establishments with far reaching financial muscle who daily spend on consumables would equate to Siglent's yearly turn over by many multiples. Yet even with a fair wind and the right people in the right places nothing ever happened that fast  :-//

So how do you find the time to do all of this? and keep your distribution customers happy, answer tech queries none those forum based, day to day running of a SME plus find ALL the time hang around on EEV?

Astonishing abilities TT I am in awe of your omnipresence.

Which gives us a couple of possibilities, Tautech is in fact a persona created by a number of users all keyed to the same response algorithm who's 24/7 EEV vigil is maintained seamlessly.

Or Elvis never really left the building   :clap:

Possibly you have alien DNA that allows you 1.75 hours sleep a day, live off 2 NASA ration packs a year, juggle 47 steins (all full) while computing pi to 35th power while still making replies on EEV blog forum

Are you a top secrete Siglent project they have been working for the last decade? not just to surreptitiously take out Rigol et al and slowly work towards world domination via T&E data acquisition back to the mother factory?

So do indulge an old man and let us know your special Siglent power and do you ever need to recharge it?

PS what's next Siglent 2020 release portfolio?, must be due very soon, you know you are itching to spread the love to us all.

After all its only been a couple of months since the last product drop

There are new features they left out of the release notes, the best of which is addition of log frequency sweep in VNA mode.  I love this feature!
Also they fixed a bug that decoupled markers when you went into continuous valley or peak mode using the VNA.

It should have done its thing by now and as 2.7 was pulled it may have had some bug in it.
I rolled back to 2.5 from 2.7 a few weeks back after it didn't behave as I was used to yet 2.5 did.  :-//

Stab the power button for 2s and give it time to shut down. If that doesn't work hold a sec more and give it a mo.
If still no shutdown hold the button down until it does.

Then power ON again and check System status for changes. If none, roll back to 2.5 then update to 2.8 because we know that process works.

FULL BACKUP of a SVA1015X or SVA1032X


Scripts to make a NAND dump + RAM dump + firmdata0 backup on a SVA1015X or SVA1032X are attached.  (Tested OK.)

Use a pendisk >= 1 GBytes.  It can take up to 20 minutes.

Edit: I added a command to reboot the SVA after the backup is complete.

@TV84,

Yes it did work ok for me. Still on 2.2.1.2.7 in pro-mode with FAT32 8GB stick.
It is difficult to see if the dump is ready. I waited for 35 mins before shutting off

Also today installed the missing link. Used RG316D to correct(My unit originally shipped with 2.2.1.2.3r1, august 2018 so probably one of the first batches)
Now upgrade to 2.2.1.2.8

Many thanks to tv84 who walked me through crossflashing an SSA3021X Plus to a full functional SVA1032X.
His patience and knowledge was much appreciated. Need to send him a crate of beer :popcorn:
Make sure that you use his full NAND backup .ADS before you start.

Shows Model as SSA3032X Plus but that doesn't bother me. Quite fancy Elasia's 'TurboEncabulator_5000'
Serial number remains intact.

I needed to have the impedance information from my SVA1032X VNA. Unfortunately, this device does not directly support such a format, so I attempted to connect it over TCP/IP to Matlab.
Provided *.m script supports only basic operations in SA and VNA modes, anyhow I hope someone will find it useful.

Attached, you can see an evaluation of the sample RFID antenna, operated at 13.56MHz: SVA1032 screen and Matlab files - acquired S11, Smith and Z. Also an example of sampled analyzer data.

Feel free to modify this script as you wish. You need only to change *.c extension to *.m (m file type is not supported to be posted on forum).

Who knows, if the firmware update to the latest 2.2.1.2.8 version violates the existing calibration certificate? I'm worrying, that this reflash process may irreversibly overwrite some internal calibration data of the unit.

Is it a safe process from this standpoint?

I found only below remark:
"CAUTION: User calibration data taken with previous firmware revisions will no longer be compatible with the instrument after upgrading to V2.8. You will have to store new user calibration files if you update the instrument", but I believe it is related to the calibration performed during OPEN-SHORT-LOAD, which could be easily repeated in a VNA mode.

What about (possible) accuracy degradation in a spectrum analyzer mode? I assume, there are some manufacturer's correction factors, which typically reduce internal errors (due to linearity, drifts etc.). Are they maintained, discarded, or switched to default ones?

Or maybe there is nothing to worry about? Did anyone experience any degradation in the accuracy after reflash?

Thanks tv84 for that response.

However, it might not be as simple as you've described, also for the top suppliers...

"...E6452A receivers the amplitude accuracy may no longer meet its published amplitude calibration specifications (by 1 to 4 dB). This is due to a firmware upgrade that changes the tuning equation of the E6452A. Affected receivers should be returned to an Keysight service center for a complimentary (no charge) calibration that will restore your receiver to its specified performance"

The Caution only applies to existing user saved VNA Cal's and has no impact on other functionality.
The preexisting VNA Cal files preloaded at the factory remain for basic functionality.

All this implies you already have a set of VNA Cal standards on hand and can repeat and reload them.

Yes, only in VNA mode.

OK,

Did the upgrade on my SVA1032X(ex SSA). Was suspicious at first as the file size was several MB less than the previous update.
At first I couldn't find the user calibration entry. However pressing the user 1 or user 2 again, a new menu appears where the parameters can be entered.
Now back to the theory to find out how to determine the proper values on my calibration set.

Does anyone think, that Siglent engineers responsible for firmware development of SVA1032X VNA may occasionally look into the content of this forum and look for kind of inspiration for the next releases of the product...? :)

If this is a case, I do have some proposals, which (for me) may enhance device functionality:
1. Impedance (Z) and admitance (Y) results presentation format, both during S11 and S21 measurement. It is present with Smith chart, but not in a trace mode
2. Direct save of current trace(s) to s2p file (local and USB)

Any other ideas?

Anyone try the User defined cal loads? The Define Load  "Delay Terminal" and "Impedance" are greyed out.

Also when invoking Port Extensions with a RG142 type N 30cm cable "Auto Open Port1" returns "Delay Port1" with numbers like ~18us, and Length Port1 of ~3Km!! Before this firmware update, this provided the correct values in ps and mm!

Best,

Indeed, "Auto Open Port1" is broken, downgraded and it's fine. "Define Load" options are still greyed out though, not that I've ever gone down to this level before, and it may be normal.

Yep confirmed same problem here and reported it to the Product Manager.

Greying out the options which are not implemented yet is pretty standard for what we've seen to date. But there is no way to define a load on the device for now, it is assumed to be perfect in a user cal, or it uses a pre-measured data file for the defined cal kits.

IMHO if you are looking for the absolute best accuracy from the device, the do the calibration on a PC where you have many more options for using the best correction data. It is a bit cumbersome to extract the data, it requires a manual conversion from the csv file to a s1p file. I keep meaning to write something but never seem to get around to it...!

The second best option is to use one of the pre-defined cal-kits. The loss in accuracy is due to the difference between 'your' cal kit and the one they did the reference measurement on.

For those with telnet access and who have full cal kit data for their cal kit it's theoretically possible to update one of the factory cal data sets - of course at own risk and the change wouldn't survive major upgrades...

In future it would be awesome if Siglent supported data based cal definitions, along with a fuller featured set of parameter cal definitions and cal types. They've done an impressive job continuously improving the product so far, so here's hoping.

I am a new SVA1015X user, just received mine a few days ago.
It came with firmware 2.1.1.1.13, so I updated it to firmware 3.2.2.3.3R1 (which is reported as 3.1.2.3.3R1 on the System->Information screen!) downloaded from the Siglent NA website.
The firmware upgrade went OK, but I then tried to use the web connect feature (using Chrome browser), but it did not work at all.
I contacted Siglent NA support, and they re-produced the problem on their end, and said the work-around is to Use Firefox or IE, or use older FW re.
I then went ahead and installed firmware 2.2.1.2.8 (again downloaded from the Siglent NA web site). After this the SVA1015X is "stuck" on the screen with the Siglent splash screen only!
It will not get past the splash screen.

I did some checking, and I can confirm that the Linux based firmware is actually running; as I can use PuTTY to Telnet into the device over the LAN, and I can now connect using the web browser. but the web browser looks crippled, as there is not much there. I tried the web interface "Firmware Update" button, which loaded the .ADS firmware file, but then immediately say the update has failed.

It looks like I will need a Siglent recovery kit?
Does anyone have this for the SVA1015X?
Any other suggestions?

OK, in that case be careful and don't do anything that makes it worse.

I think that was a bad call from Siglent NA.

I guess the problem should be the same of the latest problems in crossflashing SSAX+ (go to that thread and read the last page or so).

The new SVA FW uses an app called Aladdin. The previous ones were called ecomb/ecomb_p.

The 3.1.2.3.3R1 FW knows how to deal with that change. The previous FWs do not!

So, as the filesystem space is very limited, the old app was not able to get copied into the machine (because Aladdin is still there).

My 1st suggestion would be to telnet to the machine and look in the startup script which app is being called. Then modify the name of the app Aladdin accordingly. Sync and reboot.

If my theory is correct i think that should allow you to fully boot.

If yes then reflash the old FW that you tried to flash to fully complete the operation.

I changed the startup script to run Aladdin instead of ecomb.
The instrument now boots!
Should I now go ahead and try to reflash to the older version of firmware?
System Info now shows a version of 2.2.2.3.3R1 ?
What is the best way to get this fully operational?

Tried to install the older firmware: SVA1015X_V2.2.1.2.8.ADS, but get the same result: Instrument does not completely boot up, only get the Siglent splash screen.
Restore operation, then try to re-install firmware: SVA1015X_V3.2.2.3.3R1.ADS, and the instrument now boots up normally.
The firmware version being reported is SW1: 3.2.2.3.3R1 SW2: 20200721-1 SW3: 000000CA HW:02.01.00
How can I tell if this "upgrade" to this latest version of firmware has installed correctly?
It appears that you cannot "downgrade" the firmware from a V3.2.xxx version ?
I am now back to my originally reported problem of not being able to do a web connect using the chrome browser. (or any browser)


Thanks for the help, without it I would be with a non-functioning instrument.

You should have read my previous msg more carefully. The old FW uses ecomb. You can downgrade BUT you must change the app name and script to ecomb, previously to flashing the old FW.

You solved with Alladin but that only works for FW 3.x

OK, thanks for the info.
I am a bit hesitant in making any more changes, but you are saying to modify the startup_app.sh script to execute the ecomb app instead of the Aladdin?
Right now the ecomb file is not present (removed by upgrading to V3.2.xxx ?)
Should this be done just before attempting to load in the V2.2.xxx firmware? Or after?

Sorry for the questions, and I have not done Linux stuff in a few years...

It would be nice to get the web connect working though..

What I'm saying is:

1 - Rename the app Aladdin to ecomb.
2 - Change the app called in the script to ecomb.
3 - Sync and reboot
4 - Update with the previous 2.xxx FW that you used before (which will overwrite ecomb app).

managed to get the V2.2.1.2.8 firmware running after your last set of instructions. :)
now have SW1: 2.2.1.2.8 SW2: 20200511-3 SW3: 000000CA HW: 02.01.00
And the web connect now works!
NOTE: when trying to web connect (using chrome or Microsoft Edge) with the V3.xxx fw, the browser would not connect at all. It would just timeout and fail the connection.
As soon as fw v2.xxx was loaded the web browse connect worked right away. NOTE: When using the chrome or ME browser, it now connects but the mouse pointer disappears under instrument Control, when moving over the screen portion. If I use IE browser then it works as expected. (mouse cursor does not disappear). Siglent NA support told me to use FireFox or IE. I could not use either with FW V3.xxx as it would never connect. Not sure if this is just a problem at my end?
I will stay with fw 2.2.1.2.8 for now, so I can use the web connect.
I also noticed that previous OSL calibration is no longer valid when changing firmware versions; not a big deal to re-calibrate.
I am using an HP 85032B calibration lit (Female gender)

On a different subject, what types of RF cables are people using to connect to the DUT?
I currently have a very old set of cables made with N male connectors using RG142 coax. They are quite "beat-up" (got them 2nd hand) and would like to replace them.
Is there any recommenced coax cable (sets) that people are using? Or does everybody just make their own?
If you make your own, what type of coax are you using (RG142? double-shielded?)

If this has already been discussed, my apologies.

Do you wanna stay with N-N type ?
Siglents 6 GHz rated N type cables are reasonably priced:

They also do N-SMA cables for the same cost:

Those cables look nice.
I need them to be longer, say about 2m each.
I am tuning duplexers, some of which are too large and heavy to sit on the bench, so they have to sit on the floor.
Would then need the longer cable.

So got my SDR Kits Rosenberger "Calkit" i know it's a generic one but original ones are to expensive for "Hobby use" :-(
And i think they are decent enough for my useage (hopefully)..

Now my problem is, how can i get the Calkit Parametes inside my SVA1032x? I saw user calkit buttons but the Parameters were unclear for me.
Or should i telnet in and refine / manipulate one of the saved "original" Calkits with my parameters?

Here are the calkit parameters:
https://www.sdr-kits.net/documents/Rosenberger_Female_Cal_Standards_rev5.pdf (https://www.sdr-kits.net/documents/Rosenberger_Female_Cal_Standards_rev5.pdf)

Can somebody elp me to verify which parameter inside the pdf is the correct parameter for the SVA user calkit (C1,C2,C3...)?

Best if you just use the Cal kit you have and do the calibration and save it with a name that suits you.

Some tips in the Help file:
VNA>Meas setup>Calibration

Process is:
Select VNA mode.
Enter Calibration.
Select Cal kit>Next
Select User 1 or 2 and follow calibration steps.
Enter File menu.
Set to browse file.
Change View and Save type to Cal.
Press Save on the front panel and use the keypad to name your Calibration.

Dear helpers,

I tried to upgrade my SVA1032X, natural born as SSA3021X Plus, from Firmware V3.2.2.3.2 to V3.2.2.3.3R1.

Unfortunately I used the option offered in the web service of the device. The result was a bricked unit, showing just the Siglent boot screen.

After reading of the post here regarding the ecomb <-> Aladdin issue, I opened up the device and established a terminal connection to it.

Thats's what it looks like in /usr/bin/siglent :

Code: [Select]

The last row of startup_app.sh is

Code: [Select]
/usr/bin/siglent/Aladdin &

so, it's starting correctly the application Aladdin.

Looking for the file system memory consumption gives:

Code: [Select]
Filesystem                Size      Used Available Use% Mounted on
/dev/root                61.7M     61.7M         0 100% /

ubi0_0                   82.8M      7.3M     75.4M   9% /usr/bin/siglent/usr

unfortunately evereything seems to be correct. There is no memory consuming ecomp app, also not in the subfolders.

Does anybody have an idea what to do?

File sizes, and (last line of) script, and filesystem sizes look correct.

NB. The filesystem list does not show memory usage, just filesystem sizes. The ecomb app is not a filesystem.

Can you do the following, this will tell you for sure if Aladdin is running.

  ps -ef | grep Aladdin
  689 root       6:00 /usr/bin/siglent/Aladdin    <<----- Important one!
  901 root       0.00 grep Aladdin

If you don't see it, then Aladdin hasn't started.

My wild guess:

When you do an upgrade from the USB stick, the .ADS occupies disk space in the USB disk. Then it decompresses to the filesystem upgrade dir.

When you do and upgrade via web, you must download the .ADS to the filesystem spending precious space. When it decompresses, it consumes further space...

I wonder if it is really possible to do any upgrade via web on the current SSAX+ and/or SVAs...  :-//

Try to see if you any content in the filesystem's upgrade directory and delete all that content. I would assume it should start at the next reboot...

Nonetheless, I don't fully grasp what this problem could be.

Hi tv84,

where should the upgrade directory be located?

under /usr/bin/siglent/usr/usr?

it's empty

yes ist runs:

Actually it’s not running, that is just the grep command itself. There should be another line for /usr/bin/siglent/Aladdin.

So for some reason it is not starting.

As tv84 says, try removing the upgrade contents.

Edit: Apologies. I left out the 'grep' process from the ps output for clarity (or so I thought) but have added it back in to my post.

I wonder if something wasn't copied across during the upgrade because of space filling up. Which you won't see now as any temporary files may have been removed when rebooted.

I would suggest running the upgrade (again) from a USB drive, but I have no idea how to do that from the internal serial port. @tv84 ??

Don't worry with the things that don't exist.

Ensure that you have those *.ADS and *.zip deleted.

The best is to do it via the app. Let him do the deletes and see where that goes.

There is no upgrade folder, thus there's nothing to delete.

If you capture the output from that, as a normal boot, without the USB drive plugged in, then someone may be able to spot why Aladdin is not starting on normal boot. (Attach as a text file will be best)

Hi,

The upgrade should be in folder /usr/bin/siglent/usr/usr/upgrade/.

Here you should see:

Folder: add
Folder: app
Folder: drivers
Folder: plat
Folder: sys
Folder: vnc
upgrade.sh
upgrade_add.sh
upgrade_app.sh
upgrade_drivers.sh
upgrade_plat.sh
upgrade_sys.sh
upgrade_vnc.sh

I suspect that what happend to your device was:

1) You tried to do the web upgrade
2) This downloaded the upgrade to attached USB disk
3) After extraction of files and first reboot you removed USB disk (?)
4) Upgrade was not correctly finished, because USB drive was not present

There is no official way to upgrade manually from USB, as all shell scripts would be pointing to wrong folders.

If you want to try, I can send you the contents of the upgrade folder.
I am not so sure about disk space, which is why it is always best to run the update from within Aladdin.

Anyway, you would have to:

1) mount the /usr/bin/siglent folder as rw:
mount -o sync,rw,remount /usr/bin/siglent/

2) copy the files and folders (of the archive) to /usr/bin/siglent/usr/usr/upgrade/

3) sync

4) cd /usr/bin/siglent/usr/usr/upgrade/

5) ./upgrade.sh

Send me your email per PM.

Regards,
Vitor

Unzip the .ZIP into:

/usr/bin/siglent/usr/usr/upgrade/

Sync.

Then manually launch:

Copy the files to USB, insert USB and reboot SSA.

1) Copy files from ZIP to an "upgrade" folder in the root of USB
2) Connect via telnet/serial and you should find the files on /usr/bin/siglent/usr/mass-storage/U-disk0
3) Do the mount and sync commands
4) Use cp -r upgrade /usr/bin/siglent/usr/usr to copy the upgrade folder on USB
5) sync
6) run upgrade.sh as explained before

I'm pretty sure the brick was not a fault of the user, but rather a poor implementation of the web update on behalf of Siglent.

So got my SDR Kits Rosenberger "Calkit" i know it's a generic one but original ones are to expensive for "Hobby use" :-(
And i think they are decent enough for my useage (hopefully)..

Now my problem is, how can i get the Calkit Parametes inside my SVA1032x? I saw user calkit buttons but the Parameters were unclear for me.
Or should i telnet in and refine / manipulate one of the saved "original" Calkits with my parameters?

Here are the calkit parameters:
https://www.sdr-kits.net/documents/Rosenberger_Female_Cal_Standards_rev5.pdf (https://www.sdr-kits.net/documents/Rosenberger_Female_Cal_Standards_rev5.pdf)

Can somebody elp me to verify which parameter inside the pdf is the correct parameter for the SVA user calkit (C1,C2,C3...)?

The SDR Kits are only supplied with partial calibration parameters. The only params you can use on the SVA are the delay figures in ps.

Essentially based on the params they do supply you are missing out on the limited characterisation of the load they have done.

SDR kits do a 4 wire resistance measurement of each individual load at DC and they also supply a generic parallel capacitance value in the data sheet you listed. The SVA cannot natively use either of those.
The SVA assumes that User supplied loads are perfect, and for the pre-loaded cal kits listed in the device menu it uses a generic measured data file for the load.

(Generic meaning that the parameters/data file is the same for all cal kits of the same type. The assumption they make is that all cal kits are the same within some margin of error.)

Well you _can_ enter the delay figures supplied for the short and the open into a User cal kit.
But you can't use the load DC resistance or the CII value as there is nowhere to enter them. Bear in mind that they might not improve things very much anyway.

I have one of their kits and from memory the load was pretty good even though it was marked as 48.6 ohms on the DC resistance measurement. Certainly it measured better than some 18GHz loads I got from eBay - which had better DC resistance measurements.

If you want the best accuracy then you can to get someone with a proper cal kit to measure your cal kit.
Then you can use those to do error correction of your measurements on a PC. This also has the advantage of allowing the use of lots averaging, which is not supported for SVA calibration sweeps. It is a bit of a cumbersome process though.

I'm pretty sure the brick was not a fault of the user, but rather a poor implementation of the web update on behalf of Siglent.
@Kibabalu: I would like to know what exactly happend and what you did? Did you just select "online FW update"? Did you have a USB disk inserted? Did you remove it after first reboot?

The procedure was:

1. download the FW on my machine (iMac)
2. selecting the online FW update offered from the web Front end inside the browser (Safari)
3. choosing the downloaded FW file (iMac)
4. reboot
5. brick!

The manual is stating very clearly, that a FW update has to be made by using a usb stick and initiated by the menu function of the unit, otherwise you loose warranty.

Thus, no question, it was my fault. I haven’t RTFM ;-)

But on the other side, siglent should not offer such a „trap“ inside their web front end.

In general, the web front end seems very sloppy when using browsers under macOS (tested with Safari and FireFox). It's sloppily developed, means they do not test properly, e. g. testing all functions against other operating systems than Windows too.

Try a Chrome browser.

Chrome seems to have the same minor glitches like FireFox, e. g. switching into full screen mode etc., but nothing to scary about.

But regarding the web front end the new FW is slightly worse than the old one. On the other side, the bouncing effect inside safari seems to be disappeared.

3. choosing the downloaded FW file (iMac)

Maybe it's me but I definitely didn't understand this part.

Nonetheless, maybe the online web update still points to a lower FW version which is not compatible with the new FW 3.x and that's the cause of the brick...

If the procedure of online web update is getting a file into the USB disk to flash later, then it's pratically the same as downloading it first into the USB stick and doing a local update. UNLESS the file is different or corrupted.

After clicking on "FirmwareUpdate" a file browser dialog opens up and you can search and choose a FW file. This file should then be copied somewhere, probably. Maybe this copy process didn't work properly.

Thus, it's not really an online firmware upgrade. It's more a web based front end controlled FW update process.

It's the same. I choosed the .ADS file I downloaded earlier from the Siglent support page.

The question is: What happens then? The file has to be copied and expanded from my machine somewhere into the device, most likely to /usr/bin/siglent/usr/usr/upgrade. Controlled by the web server inside the SVA. Maybe this went wrong?

The "online" update is a missleading name. What I understood is that you open the webpage of the SSA/SVA and select FW upgrade. This opens a file dialog pointing to your computer where you can select the ADS file. It is then transferred to the SSA/SVA and installed.

I think the problem is that this only works if a USB disk is attached to the SSA/SVA to store and extract the ADS file. Otherwise, it will be stored in the same folder, which is not mounted to the USB device! Apart from the lack of free memory space, because the device is not syncing this data, after a reboot it will be lost. Which is why the bricked device was complaining about the missing U-Disk0 device.

This is a serious bug! Why would you do an "online" update, if you have to insert a USB disk? Why not insert the USB disk with the ADF already copied onto it?

You don't however you can browse to a USB stick and select the ADS update file from there if you wish.

In the present GUI the firmware update labels/buttons and called Firmware Update whether they are in the instrument UI or the virtual key in the remote web sever so to call it an 'online' update as you are is misleading as the firmware update is totally done locally and mostly* works exactly as expected.  :phew:
No bug found.

* Mostly as in after the update the SVA reboots and if connected to the web server a refresh of the browser page is needed for the SVA to reconnect.

your testing scenario was upgrading from Firmware V3.2.2.3.2 to V3.2.2.3.3R1 using the web gui and everything went's fine?

Then maybe in my case I didn't wait long enough before I tried another reboot and interrupted the copying process or I just had "bad luck".

Yes the auto reboot seems to take longer to happen if using the webserver to update, however it does work even though it seems like a freeze.
Maybe some display 'please wait for reboot' message need be added for the impatient.  :)

Hmmmm  :-//

Since updating to V3.2.2.4.0, I can't use the old telnet ADS files to get back in and re-enable telnet in the startup script? This worked fine on the last update to R1.

Have they removed / moved the telnet binary?

One of the things they change is the bootloader (uboot).

Hence as tautech said: "This version can not be rolled back"

Maybe we'll see the full impact in the next episodes.  ;)

PS: Maybe this is the right time to get yourselves a full NAND backup... BEFORE doing this update.

At least it seems safe regarding the ecomb and ecomb_p names.

It should correctly upgrade no matter if the main executable is called ecomb, ecomb_p or Aladdin.

But indeed it will ugrade uImage, somthing that did not happen in any of the known/available FW releases.

uImage is the same as an old SVA1015X version.

What is definitely different from previous is the boot.bin. But can be because of the FPGA...

Post by: Bicurico on January 22, 2021, 02:04:43 pm
You are of course right.

But note that uboot.bin has already been updated by previous FW release SVA1032X_V3.2.2.3.3R1, too. So this is not the first time, but the second time this happens (at least on the FW releases I have access to),

The version in SVA1032X_V3.2.2.4.0_EN is different, though.

telnet working normal here.. no changes to busybox / link locations

Definitely not working with the telnet script from 31st May 2020.

In fact, even weirder, trying to run the script, it times out after 60 seconds. I've never had that before, used to be able to run it for as long you wished.

EDIT: Tried 2 other USB sticks to make sure, and also the SSA version, same result.

Definitely not working with the telnet script from 31st May 2020.

In fact, even weirder, trying to run the script, it times out after 60 seconds. I've never had that before, used to be able to run it for as long you wished.

I wonder if they added some kind of new validation perhaps to the file load process? Im hardwired into the debug port at all times so thats how mine works

I might bite the bullet and go in via the debug port, just out of interest to see what is going on.

I don't explicitly need telnet, but it was a comfort blanket knowing it was there.

EDIT: Tried 2 other USB sticks to make sure, and also the SSA version, same result.

Some other Siglent equipments also do that. One needs to make the script stay awake a bit longer...  :) (I didn't do that in these cases, but I could if now it's needed)

Not sure a longer timeout will help if telnet isn't starting?

I'll open it up later in the week and see what is going on, will also later try creating that file on the usb drive, but it may be expecting something in the file itself.

More than likely broken in the same way the telnet script was... tv84 will have to put out new ones to test

Works fine if you use the console to run it

Best if you just use the Cal kit you have and do the calibration and save it with a name that suits you.

Some tips in the Help file:
VNA>Meas setup>Calibration

Process is:
Select VNA mode.
Enter Calibration.
Select Cal kit>Next
Select User 1 or 2 and follow calibration steps.
Enter File menu.
Set to browse file.
Change View and Save type to Cal.
Press Save on the front panel and use the keypad to name your Calibration.
Example attached.

In use, Correction = ON

Am I correct in assuming that in such case, after the user calibration (OSLT) has been successfully performed, the status in the upper left of the screen would have to change to Cor (=calibrated)?
Now it shows --- regardless of what I do.

According to the user manual on page 76:

3.5.6 Calibration
Set calibration related items. The calibration status is displayed in the upper left corner of the screen.
The calibration status and display are as follows:
No calibration data --- (displayed in gray)
Calibrated Cor (displayed in blue)
Correction Off Off (displayed in gray)
Need to re-calibrate C? (displayed in blue)

When I shared the NSP_config_upgrade_info.xml file with @nive I noticed the contents but it didn't sink into me. Then when I saw @techneut msg (https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3453104/#msg3453104) I had a flashback!

Could it be that they made the change in FW V3.2.2.4.0? That somewhere there is a type definition based on the ProductID before the software update and ID change?

Nah, I am sure they have different components, not just the RF circuitry. I think someone did a teardown of the SVA1032X comparing it to the SVA1015X?

Unless they release a new unified hw revision to simplify the supply chain? But I doubt it.

Yep, 3 models in the SVA range each with different specs and even different instrument weights.
While flashing one to another may be possible it certainly won't meet datasheet spec.
Playing with fire certainly.  :scared:

From now on, there won't be any more "flashing one to another" as the FW will be the same. If the HW allowed it, the only difference would be in a BW license.

Ony issue I can see is that there seems to be no spectrum display in RTSA mode?    That said it might be operator error.  Other modes are working fine.

RTSA is not a SVA option. You see it because you "hacked" it.

I am deciding between a SSA3021X+ and SVA1015X, and note that from my distributor they are within 100 dollars of each other right now. So the obvious choice is the SVA1015X. Is there any reason to even consider the SSA then? I will be playing around with it in telnet, features and 3G.

I am coming from an SSA3021X (non +), and a sdrkits VNA. I could consolidate to the one device.

1.5 GHz models are a different HW platform and therefore have some different specs.
For SA use you will be giving up some of the TG capability your SSA3021X has.......study the SVA datasheet.

Thanks for the heads up Tautech. I must need to find a better set of pages to look at, because SiglentNA lists tracking generator as standard for the SVA.  :-//

I only see that the SSA has a better DANL.

Hi there, any idea why is the dynamic range for S21 measurement 20dB worse for SVA1032X than for SVA1015X? This is rather puzzling, especially since DANL is just a hair better for SVA1032X.

SSA3015X Plus and SVA1015X have a different TG spec to all other models...did you not see that ?
5 MHz minimum TG and for SVA1015X VNA mode has a 10 MHz min frequency limitation whereas for all other models it is 100 KHz for both TG and VNA modes.

This can be a no go for some and not everyone spots it whereas I'd prefer them to all be the same but HW differences don't permit it.  :(
Better you know now and make good choices armed with this knowledge otherwise the instrument might not fully suit your needs.

Hello,
 at our company, we're going to purchase one of the here discussed SSA or SVA.
We're looking at both SSA3075X-R and SVA1075X, what do you suggest?
We will mainly work on 5.8GHz digital radios and some VNA in PCB traces and antennas.

The choice is very hard, and we're not sure we need realtime (but I have some applications for it in my mind too...).

Cheers!

I would say that at this price range you should qualify for a proper demonstration and pre-sales support - at least a web-meeting.

Instead of asking the opinion of people that are unknown to you, you should be talking to a sales rep, explaining your exact needs and use cases. Only after that it would make sense to me to ask in a forum about user experience with the selected model.

Buying the wrong model may be a considerable investment loss.

Sorry for the captain obvious: The only thing I can think of is to consider if you might want to use the real time bandwidth available on the XR
- i.e. if your 5.8GHz digital radios are hopping around then you will be able to see that on the XR but not on the SVA.

Hi,
I hope you don't mind  ::) if I repeat here a question I made several days ago on a new thread "Siglent SVA1032X VNA mode: BW and sweep time are grayed" that probably went unnoticed by owners of the analyzer.
I am doing some measurements with an upgraded SSA3012X Plus in VNA mode.
When trying to measure the impedance of a 14 MHz XTAL on port 1 around resonance, I have found a very anomalous response  :o (see figure), although the instrument was correctly calibrated. The real series resonance is at a much lower resistance (a few ohms) and there is a parallel resonance around 15 kHz above the other: even a NanoVNA can show it.
My hypothesis is that the sweep time of the SVA is too fast, but I can't change it, because the relevant setting is always grayed. I have tried with the BW setting (a lower value would force a slower sweep), but it is also grayed and fixed at 10 kHz!
I have tried other measurement setups (e.g. full-span, preset, S21 instead of S11, cycle power, ...), but in VNA mode BW and sweep time are always grayed, both from the VNA stimulus page and pressing the BW/sweep buttons (see figures).

The manual refers to those commands as normally usable, only saying that the default BW is 10 kHz.   |O
I have normally used BW and sweep time settings on other VNAs (hp and Copper Mountain tech) for this purpose, when measuring devices like resonators or long lines.

Thank you very much for your help,
Roberto

Real SVA1032X fully optioned.....

Sweep Time and IFBW are greyed out when in VNA mode.
Sweep Time can influenced by the # of points selected where the minimum 201 while the max of 751 is ~1/2 speed however when the minimum can introduce interpolation errors at base frequencies due to insufficient data points and for this reason and very little sweep time penalty suffered from using the max # of points it’s recommended max is selected as used for default.
Normally we sweep over a narrow frequency range so max points results in better characterisation of the DUT and best accuracy.

I hope this will be fixed in a future release, because fast and fixed sweep time represents a serious limitation to the measurement of DUTs with significant group delay. And a lower IFBW would allow more accurate measurements.

More speed is nice but less speed is sometimes extremely mandatory.

I will take a very simple and caricatured example just so that slowing the speed will also come to mind. (not only to users mind)

Think about 10Hz wide 1MHz very steep Band Pass filter.
Yes it is "fast", even  1MHz sinewave can go through, million times per second....

How fast you can pulse modulate this 1MHz so that this modulation information goes thru this filter.
It was some year last century I heard something about iformation theory... but after tens of years I have forget most... thank god this bad memory is helpful.

Think this VNA or what ever kind of SFRA,  sweep can also think as modulated carrier what we feed to DUT and look how it react.

I think this is enough for this...  and it can turn on some light   ;)

Hello folks, i have converted from SSA3021X to SVA1032X. I have a question regarding the VNA, when looking around for images and what people have as a reading on various pages, these are what i get and do not think this is proper, but i never used a VNA before.

Can anyone please tell me if this looks right or not. Nothing is hooked up to the SVA and its an open termination.

My distance to fault is PNG16, is that a normal reading on your SVA's?

Thanks for any tips you may have.

Hi Marty,

It looks like you do have one of the rare units that is missing a interconnecting cable. There are several cases mentioned in this forum. All you need is a 50mm good shielded coaxial cable with right angled SMA male connectors.(otherwise it won't fit between board and power supply)
Unfortunately you will have to open it up for this

Hello Eric, would you have another test for me to run to double check this before i open up unit? I thought it might have been calibration or something maybe i screwed up while playing about with it.

I do have some hard line 50ohm sma coax  with right angle i could use indeed.

Thanks for the help!

Hi Marty,

I presumed you already tried to calibrate the unit using Short-open-load connections to the (left) VNA port 1in the VNA calibration menu
Reason for me to suspect the cable in your situation is the extreme deviation in the smith chart.
A good read is from post https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3086539/#msg3086539 (https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3086539/#msg3086539)

Hi Eric, ok will go read that section. No i have no Cal kits, i thought it was all done at factory. Maybe because this is an improved SSA3021X plus it is not? I guess i will need to buy a kit. They are expensive, but i suppose its a wise investment though.

In order to perform any VNA measurement you need to ALWAYS calibrate first with short, open and load.

Without doing this, any measurements are meaningless.

Marty, I suggest you investigate if your unit has the missing cable and also watch one of Daves vids on removing warranty stickers....did I really say that ?  :-X

As for VNA Cal's, you can get reasonably indicative results with the factory Cal without needing to run a Cal however the factory calibration is only to the ports and if you are to use a test lead you need use the Cal standards at the end of the cable where you would connect the DUT. What test leads and devices you might use will determine the type of Cal standard and the sex type you purchase. When they became available this is the one I got that best suits calibration at the end of SMA leads at the DUT.
https://siglentna.com/product/f603fe_female_sma_vna_cal_kit/ (https://siglentna.com/product/f603fe_female_sma_vna_cal_kit/)
In the RF board there are threads on making your own which are suitable for hobbyist measurements.

Here in these 2 threads all antenna measurements were made without calibration as the coax feedline should be considered as part of the antenna system.
https://www.eevblog.com/forum/rf-microwave/antenna-project-log/ (https://www.eevblog.com/forum/rf-microwave/antenna-project-log/)
https://www.eevblog.com/forum/rf-microwave/what-really-is-this-antenna/ (https://www.eevblog.com/forum/rf-microwave/what-really-is-this-antenna/)

All but a few measurements were single port S11 measurements and other to get similar results were with a RLB using 2 ports in SA mode.

Hi Marty, in order to check the basics, just shorting, leaving it open and placing a 50 ohm terminator will do. Measurements however require calibration with a known good set.

Hi Guys, ok so i done the simple test of opening the Unit to check cables :phew:, they are all there, and its looking sweet in there!  :-DD

Ok, here is the test with Emo's basic suggestion for testing and comparison to Tautech.

put on my adapter, then ran OPEN, SHORT and then put a 50.1Ohm BNC load. All 3 reference calibrations are done.

Here is are the results. I think they look ok now.

What do you guys think of these now? Tautech, Emo, i think this is what it should resemble. Thoughts?

And yes Bicurico, i will definetely make or buy some cal kit when i am ready so i can properly mesure my antennas and all. But for now, its a start so i can learn. Thank you for your great help!

Thanks guys!

Marty

**UPDATE** All is working fine and readings are within what is expected. I am very happy to see all is good.

Welcome to the forum.

I believe I had this happen with a SVA1015X update too.
Hold the power button down to force a hard power OFF.
It should reboot as normal then check to see if the update was successful.

2.2.1.2.5 is quite old now and you will see several improvements in later firmware.
All versions are available here:

Be sure to check the pdf in the download to see if there are upgrade steps you must do before you install the latest version.

In the update history file it specifies all later firmware versions can only be installed from V2.1.1.1.12a or later.
https://int.siglent.com/upload_file/zip/firmware/Spectrum_analyzer/SVA1000X_V2.1.1.1.13_EN.zip

I tried this version without success.

Are you sure you are using the right SVA FW update file? There are different files according to the specific SVA model. See here (https://www.eevblog.com/forum/testgear/semirandom-but-careful-mistakes/msg3363564/#msg3363564).

The SVA line will only have the same FW file after V3.2.2.4.0. And that file hasn't been released.

So, you have to use the SVA1015X_V3.2.2.4.0.ADS  (which has a CRC32: E4FD2787). It's for Product_ID 11402.

If this still doesn't work then go in via telnet and show me the contents of file NSP_trends_config_info.xml.

All SVA1015 FW versions expect a Product ID 11402.

If the upgrade fails, it might be because you changed the Product ID to a different number.

Note that the SVA1015 uses a different FW than the SVA1032 model. If you followed the hack, you probably entered a new Product ID matching the SVA1032 (Product ID 11403) instead of the SVA1015.

That might be the reason.

As I understand facotl's unit is a factory SVA1015X with only options hacked but yes there maybe has been a mistake made but FW has been updated successfully before. We will get a solution soon from the factory to fix it.

Now that we know that a hack has been done, a wrong step is the most probable cause. Maybe it would have been simpler/quicker if the member had answered my request for the contents of file NSP_trends_config_info.xml...  ::)

Hello all,

new to eevblog and have got an SVA1032x, would like to know if you have an bluetooth-dongle with keyboard or mouse in use ? I have attached a picture from the review from Shahriar where he uses a mouse.

I have a bluetooth keyboard and a dongle from Delock but can´t get it to work. I think there must be a dongle with native drivers for the SVA ?

Any advice is welcome, the keyboard would be helpful for file input.

Thank you !

Welcome to the forum.

Random MS wireless mouse dongle fitted before boot works just fine in my SVA1032X.
Check your firmware is the latest in case this matters.

Gentlemen, I've been studying this string and as I understand it, I can connect internally to my SVA1015x and make some options permanent?  I would connect internally to the uart in the unit with some sort of serial port adapter to (?) to modify or change the .ads file if my unit is running the current firmware? 
I have lots of time left on the original options grant and am currently learning the unit.  I bought this to avoid carrying my 60 pound VNA and 40 pound SA to a remote site.  I learned too late that my purchase wasn't as smart as to purchase a SSA3000+ series but afraid I would brick it.  Somewhat confused but still studying the posts...

If it's the same as with the SDS200X+ oscilloscopes, which I suspect: Wireless input devices will work because they identify as HID. Bluetooth devices will not work because you can't get them to pair and the software doesn't handle Bluetooth.

I am doing some measurements with an upgraded SSA3012X Plus in VNA mode.
...
BW and sweep time are always grayed, both from the VNA stimulus page and pressing the BW/sweep buttons.

The manual refers to those commands as normally usable, only saying that the default BW is 10 kHz.   |O
I have normally used BW and sweep time settings on other VNAs (hp and Copper Mountain tech) for this purpose, when measuring devices like resonators or long lines.


 :palm: sorry quoting myself...
I am wondering if someone in Siglent acknowledged the issue, I'd like to be sure that it gets fixed soon. Having fixed BW and sweep time in VNA mode is tremendously limiting, causing wrong measurements on e.g. high-Q resonators like xtals and long lines.

Yes this is an issue we have recently explored in some depth with the SSA/SVA product manager and for now SA rather than VNA mode is better for this where you have more control over BW and Sweep times.
Currently we are waiting for a firmware update to improve Sweep, RBW and VBW performance and fix a related bug found while exploring these issues.
Hopefully SA mode will give you reasonable results until this gets fixed.

Is it normal to get an ADC overload warning in VNA mode with default settings and nothing connected?

Default after pressing the Preset button is S11 with tracking gen set to -5 dBm. And that's fresh out of the box without doing a port calibration yet.

The warning goes away when dialing down the tracking generator to -7 dBm or less.

On my SVA1032X the VNA default settings are Tracking Generator -5dBm, Attenuator is grayed-out but shows +15dB so there should not be any overload. When I push the dynamic-range to maximum in s21mode TG -5dBm and Att 5dB it beeps from time to time but gives with 4 Averages about 100dB to measure duplexers and filters.  ;D

Maybe not. Is yours an ex SSA unit of factory SVA ?
Hacked units can produce weird results until a VNA Cal is done.

You could try a rough bush Cal with SOL's for a Port 1 Short, Port 1 Open and a 51R Load to see if that settles it down.

Post some screenshots.

Not hacked (yet). Luckily I got the real thing as I was worried about support in case something goes wrong with the VNA side. :phew: It's already on its way back. I contacted Siglent NA and they also thought that port 1 of the unit is defective.

In particular, without the ability to export touchstone files or set the VNA sweep time, the SVA1032X is little more than a toy.

I don't understand how such basic features can be missing. Its almost as if the firmware developers have never used a real VNA.  :palm:

I have a question (possible bug I found?) about the EMI software package.

I am taking EMI measurements through a 10dB attenuator. Based on the manual I need to set the "Ref Offset" value in the Amplitude menu to match the external attenuator.

When in normal spectrum analyzer setting the "Ref Offset" value does shift the amplitude of the plot by the correct amount. If I enter 10dB the entire curve shifts up by 10dB on the scale.

However, when in the EMI mode setting the "Ref Offset" value shifts everything, including the scale and the limit mask. This means that all the readings and the limit mask for checking EMI emissions levels is incorrect if there is any external attenuator that is corrected via the "Ref Offset" value.

Am I misunderstanding something? The behavior seems to be correct for just spectrum analyzer mode. I looked through all the options specific to the EMI mode and I do not see any alternative way to set a ref offset value. The limit masks can be shifted up or down, but that still means that all the amplitude values are incorrect with an external attenuator.

Hi

I used the SVA1032X Plus  in VNA mode to determine return loss of a 2.4Ghz sector antenna.  Wanting to home in on the area between 2.4 and 2.5Ghz I set the lower and upper frequencies accordingly.

A previous VNA then would have me perform SOLT calibration for this range. When trying to do this on the SVA1032X Plus it always resets the lower to 100khz and upper to 3.2Ghz with 751 points.

It doesn't allow me to calibrate between 2.4 and 2.5Ghz at 751 points. I have been using cabling and connectors more suited to lower frequencies and that seemed rather twitchy up at 2.4Ghz. Is it not possible to calibrate over a limited frequency range to decrease the intervals between calibration points ?  I have since invested in better quality cabling/connectors (ouch!) but I am still interested to know if I am missing something or if this is normal behaviour.

I'd be grateful for any info.

Thanks

Eloso

Doesn't sound normal to me, unless that model SVA has some issue with small step sizes or its a FW bug.

I assume you're doing something pretty similar to this?

* Change to VNA mode
* Press Frequency button
* Press Start Freq and set to 2.4 GHz
* Press Stop Freq and set to 2.5 GHz
* Press Sweep and change points to 751
* Press Meas, Calibration, Calibrate, 1 Port and follow the procedure. Apply the Cal.

I'll ask Tautech to check on his box.

Post by: eloso on September 06, 2021, 01:25:54 am
Yes. I just repeated the procedure with a fresh mind on a fresh day.

The behaviour is just the same - when you press calibrate, calibrate, 1-port the frequency range always resets to 100khz to 3.2Ghz.

Subsequently pressing Frequency, setting the range up again leaves no option other than to press measure, calibrate etc etc and the same thing happens again.

BUT this time, the third time around while staring somewhat exasperated at the screen I had a hunch and pressed the screen region over the "100khz" under the graph and was delighted to find a little keypad pop up which allowed me to change the start frequency. Then I could do the same with the end frequency. Now I can continue calibration without actually having to press "calibrate" again (which would reset the span).

So problem is resolved.

I don't normally use the touch screen much (don't like fingermarks!) and am bemused at the behaviour wherebye the SVA resets the frequency just by pressing "Calibrate" button.  You can call this a bug, or a feature.  Regardless, there is nothing of this in the manual and I trust it is of help to others who want to do the same thing.  I'm not very experienced above a few hundred Mhz but from how twitchy things seem to become I would have thought calibrating a VNA in the range that you intend to use it is mandatory every time.

I was going to add that my instrument started out life as a SSA but everything I have read and what I understand tells me that this couldn't be responsible for the forementioned "bug/feature".


Thanks for taking the trouble to look, and if someone else could verifiy what I have found it might be nice.

Cheers

Has anyone actually used the EMI software package? As I previously said, it does not seem that the Ref Offset value is being correctly interpreted in the EMI mode, leading to incorrect amplitude values.

Here are two screenshots showing the Ref Offset at 0dB and 10dB. As it can be seen, only the Ref level changes. However, the expected behavior should be that the the whole plot should be shifted by 10 dBuV relative to the Y axis while the limit line stays the same. In normal spectrum analyzer mode the Ref Offset does shift the entire plot up/down by the corresponding dB value.

Am I grossly misinterpreting something, or is this actually a software bug?

The behaviour is just the same - when you press calibrate, calibrate, 1-port the frequency range always resets to 100khz to 3.2Ghz.


I have a SVA1032X, born SVA1032X, with SW 3.2.2.4.0 20201220-1 and in this unit the freq does not change

Works ok on mine too, upgraded SSA3021X, same software versions.

Wow Thanks ! - I guess it was kind of obvious but yes, plugging in a mouse really makes a difference - recommended !  :-+

There are still unresolved issues around VNA calibration and saving of calibration.

One has been referred to already by Ghislain


Am I correct in assuming that in such case, after the user calibration (OSLT) has been successfully performed, the status in the upper left of the screen would have to change to Cor (=calibrated)?
Now it shows --- regardless of what I do.

According to the user manual on page 76:

3.5.6 Calibration
Set calibration related items. The calibration status is displayed in the upper left corner of the screen.
The calibration status and display are as follows:
No calibration data --- (displayed in gray)
Calibrated Cor (displayed in blue)
Correction Off Off (displayed in gray)
Need to re-calibrate C? (displayed in blue)


I experience the same - the unit seems to be calibrated (I know this becuase I am calibrating with a known dodgy load and it accounts for it perfectly). But it is disconcerting to see that the status is ---

I did find that if I do 1-port Cal followed by just an "Open" Cal the status changes to "Cor" and the 1-port cal is not lost. So there is another good work around.

It begs the question:  What is the point of having a menu option just for "Open" calibration and another for "Short" Calibration when there is none for "Load" Calibration ? I mean if you want to do a calibration you either select "1-port" or "Through" which include all elements.

OK, next problem. When you Save the calibration to a file, switch the instrument off, switch on again, it has lost the calibration. Aha - but you saved it to a file ? Load the file and, yes you guessed it, you have still not got your calibration back. The only answer is to repeat the calibration.

Now this is not a huge problem because I think you probably need to calibrate at every use anyway - especially if you've had the instrument off and come back for another session. But you are supposed to be able to do this and it makes me queasy that if some of these small items don't work, what is there that also doesn't work and that might give you really dodgy results when you don't realise it?

After having read everything I can find, I am now starting to think that this might all be down to the unit being an "upgraded" SSA. Perhaps the firmware is trying to deal with a use case that it wasn't written for - like maybe there isn't a proper factory VNA calibration file and it is getting into a twist as it tries to combine a non-existent file with a user cal file.

I did have a look at the logs and thought I may have the answer but there are log entries to say successful factory vector calibration applied, so it probably isn't that after all. But perhaps something similar that I haven't thought of ?

Quick answer to part of it, this might clear up a bit of confusion:

The Open and Short calibrations are not part of the 1 Port cal. Instead they are for quick, approximate cals where you only use one standard.
The data is being normalised to a standard - almost the same thing as if you 'Save Data' to Memory and use the Data/Mem math function.

A quick test suggests that this Open Cal is not exactly the same thing as the Data/Mem math function as there is a -21ps delay coming from somewhere.  I haven't researched it further.
There is no directivity correction of course.

A load calibration on its own would be bit different - one point is that a perfect load has no reflection and so can't be used to normalise phase or magnitude.

I did come up with a quick and dirty, poor mans calibration at one stage. From memory it was like this:

* Sweep the open port/open ended test cable - use that as the open standard measurement
* Alter the open sweep data by 180 degrees - use that as the short standard measurement.
* Sweep a real load.
* Calculate the correction in the normal way.

I'm sure there are better ways to do it, that was just something I dreamed up.

The trick is to change the Save type to a Cal file type so it gets stored internally and is accessible to load again.

Thanks everyone.

Yes I am on latest firmware. 3.2.2.4.0.r2 is displayed on the System Screen.

And sorry but no, the answer is not to change the file type to CAL. I have already done this as a matter of course.

Interestingly, loading a saved CAL file does make a difference - ever so slight difference to the display. But it is a long way from being what it should be. I am using a very good 50 ohm load and a fairly dodgy one, in order to give me a reliable baseline and test subject.

I have heard two folk say now that this behaviour is not apparent on their instruments.  I am wondering if there is an issue relating to it being an upgraded machine rather than a native born one.  It would be really helpful if folk can state if their machine was purchased as an SVA1032X or was transformed into one.


I had no problem with the upgrade and Linux has been part of my career for a long time. I have checked several times and looked at several different (but more or less the same of course) descriptions of the upgrade process so am as confident as it is possible to be that the upgrade went according to plan and should be just like everyone else's.  I'm experienced enough also to know that this may not be the case of course and I may have made a mistake.

p.s. The three issues in a nutshell are

1. The resetting of the stimulus to 100khz-3.2Ghz when pressing 1-port, calibrate, calibrate.
2. The stubborn refusal for the cal status indicator to show anything other than "---" after the 1-port calibration routine and
3. The incorrect calibration status after loading a previously saved CAL file.   

Just to clarify, there is no error message, nor indication that the loaded CAL failed.  It is just that the instrument doesn't go back to the proper calibrated state that it was in when the CAL data was saved. This is evidenced by the trace of a 50 ohm load  that is lossy above 2Ghz but that is used for calibration. After calibration the load of course looks perfectly flat.  Switch off, switch on, load the cal file and it reverts to its true picture of poor return loss.

Ok, I think I've found a/the problem:

There must be a calibration done first before loading the cal has any effect.

I tested by doing an 'open cal'  with a load on the port (because it was quicker as it only requires a single standard).
(Note that I used a Load here instead of an Open on purpose, I wanted the calibration to be obviously different to what is normally shown)

After the cal was completed, I applied it and then removed the load from the port.
The trace moves up to 30-40dB, and is obviously different to what an open port would normally show (which is a flat line at 0dB)

Then I saved the cal, reset the machine and loaded the cal again.
Observed that nothing changed, which is a bug.

Then I did an open cal with the port open, and applied that cal.
Now I loaded the saved cal again, and this time it shows the expected trace from the saved cal.

Hi everyone,

I bought an SVA1032X as my first VNA. I have a concern about it though. After a fresh calibration using the "enhanced response" cal, looking into the instrument and measuring the S11 it doesn't seem to be very well matched. Any chance anyone else can confirm this with their unit? The VNAs I've used at work don't have this kind of response so I'm curious as to why mine looks like this.

First picture[attach=1] is what I'm concerned about, second picture[attach=2] is the test setup.

Thanks!

Looks wrong to me, but I haven't used it myself. Make sure you are on the latest FW as there have been improvements with the calcs.

I am not in a position to replicate at the moment - but just wondering if you can post the same picture using just an OSL cal?
Also the measurement of the same load used in the cal - for both a 1 Port cal and an Enhanced Response cal.

That should show if the Enhanced response is doing anything at all, or just not improving the port 2 match.

I am not a sva1032x owner but the graph seems credible. It represents the s11 of port 2 (which is usually not very efficient in terms of vswr) seen through a transmission line less than a meter long.

Trawled through some old documents to refresh the memory, and I think that it depends upon which version of "Enhanced Response" is implemented.

The version in this document was the one I had in my head. I've commented on it before, and (assuming I'm understanding it correctly) then it does correct for load match. (e22):
https://www.researchgate.net/publication/263306917_1_GHz_Automatic_2-Port_Vector_Network_Analyzer_Using_Common_Laboratory_Instruments (https://www.researchgate.net/publication/263306917_1_GHz_Automatic_2-Port_Vector_Network_Analyzer_Using_Common_Laboratory_Instruments)

However, it is most likely you are right and Siglent have implemented the more simplistic HP version. That doesn't correct for Load match and is just an OSL cal plus Thru normalisation:

I found some bugs with my crossflashed SVA1032X - firmware 3.2.2.4.0

1.Very often but not every time: after powering on, having previously selected vector analyzer mode with applied user calibration, the device starts without applying the user calibration.
Even more - correction button is "On" state and 'Cor' is showed. When I press the correction button (On/Off), it works in opposite - when corrections are off, actually user calibrations are applyed, and when corrections are on, calibration is not applied.
This problem remains so either until a new calibration is performed or until the mode of the instrument is changed and returned to the vector analyzer.

2. Very often when making a 1-port calibration the process does not finish - the device does not complete some measurement(open/short/load) and it is necessary to select the calibration process again. This happens more often when working with more points - for example 751. Is it possible that this problem is due to the fact that the instrument is cross-flashed and does not have a factory calibration of the vector analyzer?

Does it happen only on crossflashed units or all SVA units?  Mine has similar symptoms but it is crossflashed. We will need confirmation from an original SVA unit

I have experienced this and a variety of quirks on my cross-flashed unit.  I do use the instrument mostly below 500Mhz and I often use my genuine Deepelec NanoVNA in preference to the Siglent because it just kind of works better and provides sufficient precision.  Yhat's a bit sad really from the Siglent point of view but let's face it, I am getting benefits from Siglent cross flashing that are essentially free so no complaints there at all - in fact just gratitude for all the work that has been done to help me upgrade the instrument.

I have a lot of experience in software development and I do have a sneaky suspicion that the software has been written to include code that expects a factory calibration file to exist and that causes some unexpected nehaviour if it doesn't.  I would love to try out someone elses factory calibration file, or even convert one of my own user cal files to become the factory calibration if it turns out they are in the same format.  It matters not a jot if the factory cal isn't the right one for that machine, what would be important is that it exists in the right place to be picked up by the code that otherwise misbehaves if it unexpectedly doesn't find it.

Is there a dump of the file system available anywhere of an original genuine SVA or can some kind person make one available? Or perhaps just a factory cal file or a dump of the cal directories to allow me to make my own investigation ? Or just more info about the factory cal file format/naming ?

Thanks !

Indeed, it looks like the "original" SVA1000X has 2 more files than an original SSA3000X+.

Try them to see if it solves the problem.

My cross-flashed SVA1032X does indeed already have these two files in the firmdata0/cali directory.  File sizes are identical. sha256 checksums are different to those of the files you attached. My own version are datestamped to coincide with the last calibration that I carried out earlier today.

Nevertheless, I made full backups of everything as usual and swapped the files for those that you have attached.

This doesn't appear to have made any difference to the quirky behaviour I have documented earlier.

It was a nice thought but perhaps we are barking up the wrong tree. Unless there are factory calibration files elsewhere. Rather than comparing file lists from an SSA with a genuine SVA can we compare filelists from a genuine SVA with my upgraded version ?  I can do this if someone can provide a full treelist of files from a genuine SVA.

The thought of missing calib files was good. The thought of something missing elsewhere doesn't make much sense. All other files probably are installed by a FW package.

Do you want the full calib directory of a SVA1032X to replace yours?

Yes, I am sure you are right.

In the early days incidentally I checked my debug log and there were many entries pertaining to factory calibration data file load  failing. Curiously this changed at some point and for the last month I regularly get messages to say factory calibration file load was a success.  There is even a huge string of exclamation marks after it (did the author think that success was such a rare event that exclamation marks would be needed ?  :)  )

I don't think there is much mileage in me trying to take this any further. Wait and see if anyone else reports anomalous behaviour in VNA mode. At the end of the day it seems to work fine and gives the kind of results I would expect when using the little tricks and workarounds.

Thanks for stepping in.

My crossflashed device did not have factory cali files for vna. Now i copied other device files (from tv84) and things look an idea better.

Issue 1 (post#641) with the state of the user correction after powerOn remains.  :(
It will soon become clear whether issue 2 with random failed user calibrations will disappear.

Here it's examined and it's very interesting, but there is little or nothing about the disassembly procedure.
You will see the N connectors, that are flange type, screwed to the PCB and certainly to the board shielding box. I don't understand how they could become loose.

I believe it is my fault. When I ordered it, I immediately went on RFParts and got some nice port savers for it (that added some torque sticking out an inch and a half) and then I mistakenly ordered RG-142 instead of RG-400 for my test cables, which are stiffer than most test cables. I am sure I have applied a bit more stress on the ports than I should have. It is just the tiniest amount of play, barely noticeable. There will be some lock-tite going on those screws and the two they omitted will also go in to make it 4 fasteners total.

Managed to tighten it. Although the shielding does utilize the unused holes in the N connector, it does not tighten down on the actual connector. There is enough gap between the machined aluminum shield and the N connector such that tightening the screws that pass through it merely apply additional force holding the aluminum to the board but not any to hold the connector to the board. Only two of the 4 screws secure the N connector to the board.

The screws in the shield were tight, but when I got to the two on the N connector, they were finger loose. I wonder if they forgot to tighten them..

These are the FTP commands for uploading files:

CD target directory <-- change directory in target system (SVA)
BIN <-- binary file transfer mode.  Default can be text and it will mess up your file
PUT filename <-- send file from your PC/laptop to the target system (SVA)

You might not have write permission with the "ftp" user, I have not transferred to the SVA using FTP yet.  Maybe others can confirm if login as root is needed

You better not mess withe filesystem if you don't know what you are doing.

Also, to copy those files, the partition has to be made writeable.

Please read on how to do that and how to sync the drive afterwards.

This is explained in the hacking threads of the SSA3000X.

As well as the good advice from Vitor, if you run the df command, it will show which filesystems are mounted, and one of them will be your USB device, including the file path (assuming you have it plugged in).

Week after adding the factory calibration files for vna and intensive work in VNA mode, the issue of random not completing the calibration process did not appear.  :)

Another thing I notice but I'm not entirely sure about is an improvement in the performance of the "port extension". I remember that before without the factory calibration files the use of the port extension did not work properly, but now it is very precise (although calib files are not exactly for this hardware). But this suspicion must be checked.

Hi !

so I upgraded my SSA3032X+ to SVA1032X.

But now my calibration after power on is always really messed up ...

Reading through the set, it is not clear to me, should I copy the calibration files in firmdata0/cali from my SSA backup to the newly upgraded SVA ?

Also, I feel like I'll have to get a calibration kit to get any meaning result. The crap I have from NanoVNA, is, well, crap ...

I am thinking of the Siglent F603ME (most of the interfaces I deal with will be SMA based, so I'm thinking that would be the best choice.
Or am I wrong ?  Should I get the N-Style ?

Is it ok to ask here if anybody knows af the cheapest source for these kits ?

Many Thanks Guys & Gals !

F603ME is what I ended up getting as certainly you mostly want to work with SMA however you can cobble together workable Cal standards that will give reasonable results however you must have a known Cal to start with and only quite reasonable Cal kits with give good results over the entire frequency sweep.

You also need decide it you will work with N-SMA adapters so to minimize the wear on the N type inputs and if you do and so use plain SMA cables the ongoing costs and those of getting set up is reduced although if you need predicable accuracy down in the tenths of dB you have to shell out for good cabling.....but will you use it often is what I've asked myself so have a selection of lower and higher cost cabling and adapters now.

Thank you for your reply, TauTech!

Yeah I need to find a reseller with a good price for that cal kit ;)

Most of the cables I have is RG316, which I think is not recommended above 1ghz.

I ordered two sets of N to SMA cables, one using LMR195 and the other LMR300 cables. These are rated up to 6 GHz and have very low loss.
See my post above ...

Hi everyone,

I bought an SVA1032X as my first VNA. I have a concern about it though. After a fresh calibration using the "enhanced response" cal, looking into the instrument and measuring the S11 it doesn't seem to be very well matched. Any chance anyone else can confirm this with their unit? The VNAs I've used at work don't have this kind of response so I'm curious as to why mine looks like this.

First picture (Attachment Link) is what I'm concerned about, second picture (Attachment Link) is the test setup.

Thanks!

Not sure if this was answered yet or not ...

Looks like in your setup, you are using RG316 cables. These are only good to about 1GHz.

Reduce your stop frequency to 1 GHz, and you should be closer to a "dot".

I am seriously interested in purchasing a SVA1032X.
Is there any owner, based on his experience with the instrument, able to briefly present the pros and cons of the spectrum analyzer and the VNA section respectively?

The various software options available (Advance Measurement Kit, Distance to Fault, EMI, Digital and Analog Modulation Analysis) are very interesting but out of my budget. Anyway, I seem to understand that all these options are available in demo mode (i.e. limited time).
If so, is there any trick to extend their durability over time?

Thank you very much to those who want to help me decide whether or not to proceed with the purchase.

Only that it's just a single port VNA therefore measurements are limited to S11 and S21 types as all stimulus comes from Port 1 (TG) yet for antenna (S11) and one directional tests of filters etc (S21)) it's still very useful.
For DUT's that need testing/measuring in both directions they must be flipped to poke them from either end.

The SVA1032X has a considerable cost and before proceeding with its purchase I need to be sure if the various SW options (the cost of which is prohibitive for my possibilities...) can be permanently enabled.

Thanks a lot for the suggestion!!! Before purchasing I'll investigate a bit regardig this much less expensive option.

Anyway, regarding this possibility that I'll now explore in detail thanks to your suggestion, I have the doubt that the frequency expansion operated in the transition between 2.1 GHz and 3.2 GHz results in an uncalibrated spectrum analyzer in the 2.1 - 3.2 GHz range and this would be a not negligible inconvenience for this type of measuring instruments! (calibration of a Spectrum Analyzer is usually a very expensive service...)

Speaking as a (soon to be retired) professional radio design engineer a one and a half port VNA is cumbersome at best for professional use. It can do the job but you will forever long for a two or four port VNA. Speaking as a hobbiest I would say that these are very fine instruments. They are much better than I ever dreamed of owning except in the form of old, tired boatanchors that take up space, weigh a ton, and live on borrowed time.

I have a SVA1032X which used to be an SSA3021X Plus and I'm seeing some strange issues with the VNA calibration. It seems that when I do a calibration, using either the Open, Short, or Enhanced Response calibration modes, things work OK and I get a "Cor" message to indicate things are calibrated. The issue comes up when I use either the 1-Port or Response Through calibration modes. Whenever I enter them, the start and stop frequencies always get reset to 100kHz-3.2Ghz. I can change them when in cal mode by clicking on them under the graph, but either way, when the cal completes, I never get the "Cor" message at the top indicating things are calibrated. Nor do I get a "*" next to the calibration option in the calibrate menu. Instead it always shows "---" at the top. Things seem like they might be calibrated, so I'm not sure if this is just a bug. Can someone with a real SVA1032X check if this happens there also?

The 2nd thing, I'm wondering about is the the cal kit selection. I have the F603FE kit from Siglent and select that from the menu when doing cals, but I noticed that there isn't a CSV file for it in the vnacalkitdata directory even though it's showing up in the menu. Does anyone know if that is an issue or how the CSV is used?

I'm referring to the CSV files not the CAL files. The CSV files are located in the directory structure at
Code: [Select]
/usr/bin/siglent/usr/vnacalikitdata Are you saying that saving and loading a CAL file will produce a CSV file? The files in the vnacalkitdata directory seem to be installed from the factory for only certain mechanical cal kits.

Cal kit files will be individual characterizations of each model of the listed Cal kits.
However these are not the industry standard Touchstone files although we are urging Siglent to use them....however they seem to rather want to sell Cal kits.  :(

Playing with a new beta FW for my SVA1032X and would need to roll back to known good FW to do further checks for you..........

The strange thing is that the cal kit CSV files in that folder are only for a subset of the calkit options you can pick from the menus. Makes me wonder if I pick the F603FE and the CSV file does not exist, then what is actually happening?

I don't suppose you can tell us if the new beta has fixes for the weird cal issues I mentioned above when selecting 1-port or through calibration, etc.?  :-+ :popcorn:

I have one. I always use the 1-port cal and I just tried the Response Through cal.  The frequency settings follow into both calibration screens and it also shows CAL at the top after leaving the cal screens.

A wee look at this beta FW and Cals.
Some screenshots below with what might be the new max points.  :)
Going through the Cal process for which I used 1 Port Cal as this is mostly what I use and for this a F603FE at the end of a cheap 150mm SMA cable on a N-SMA adapter on Port 1.
Captures for Short and Open were done in the Sort and Open cal and went through them again in the 1 Port Cal where Load is also used but at each step each Cal is Applied however you only see the full result after Load is done.
Marker @ 3.2 GHz added FYI.
Full BW sweeps were quite fast previously however with 10k points they're ~4.5s now.

Thanks! This is good info to have. It means that there is some difference between a real SVA1032X and a converted one. Anyone have any ideas on why this might be or how to fix it? I saw earlier in the thread that I'm not the only one with this issue.

My converted SSA3021X Plus works ok with the calibration steps you have highlighted for both "1-Port" and "Response Through". The "Cor" indication appears when calibration is applied, and the frequency remains at whatever I had previously selected.

My converted SSA3021X Plus works ok with the calibration steps you have highlighted for both "1-Port" and "Response Through". The "Cor" indication appears when calibration is applied, and the frequency remains at whatever I had previously selected.

Are you doing these without doing a save/load file? From boot up, I'm simply doing the following for example:
1. Mode -> Vector Network Analyzer
2. Stimulus -> Start Freq -> 10Mhz -> Stop Freq -> 100Mhz
3. Back Arrow (Not the back button next to the number pad, but the blue button with the left pointing arrow)
4. Calibration -> Cal Kit -> F603FE
6. Calibrate -> 1-Port Cal -> Calibrate
The screen now changes to the prompt to connect the [OPEN] module, but the start and stop frequencies are changed to 100kHz - 3.2Ghz.

If I proceed through the cal it seems to work, but I don't get "Cor" (nor does saving/loading a xxx.cal file seem to do anything.)

A couple of other things I've noticed...

I've previously done all 5 of the cals modes, and the working ones seem to automatically save somewhere and the system knows that, so if I go into Calibration -> Calibrate and select Open Cal for example, the "Apply" button is enabled. I can only ever get the "Apply" button to enable for Open, Short or Enhanced. I can never get it to enable for the 1-port or the through. I'm thinking something is messed up with those 2 modes.

If I save a xxx.cal file and then try to load it, nothing appears to happen as well.

I also noticed that after the 1-port cal, it prompts me if I want to apply the cal by hitting Enter. When I press Enter, it then hangs for a few seconds and then beeps. For the open or short cal's for example, I don't get prompted if I want to apply, it just does it. I'm not sure if the few second hang or the prompt to apply in the 1-port but not the open or short is normal either.

Anyone have any thoughts or suggestions or what I can try to correct this? Maybe there are some files I could delete or overwrite in the file system to reset something?
Is there something I should be doing that I'm not? I'm kind of at a loss here and I'm not sure what else to try...  |O :-// :palm:

(I'm looking forward to @tautech's save/load examples :) )

Steve, I suspect you are missing a small but very important step.  ;)
Work through 1 Port Cal as you have then re-enter the Calibration menu and select Correction = ON.

Screenshots below just taken show first what a Load looks like with Correction not applied and then applied.

This is interesting... By default my Correction is on, so I never touched it. I will have to try switching it OFF before doing the cal and then switching it back ON after to see if that makes a difference. I'll try this out tonight.

Is your Correction defaulting to OFF?

Mine turns on the calibration automatically once the OSL cal is complete. It would be interesting to make up a few reactive test loads and filters and actually get a comparison on different spans. For instance, mine is a legit 1032x, I have the certificate and I have the cal kit. I would have no problem getting a test piece in the mail, posting my results then mailing the board to someone with an upgraded SSA so they can do the same. Then we would know for sure what what the SSA version was doing in comparison to the true 1032x.

No and why would one undertake a calibration process with correction ON ? Dunno if it makes a difference or not. it just seems logical to disable corrections. Anyways I'm working with a V5 beta and just got an update that's apparently soon to be released so I need get all my checks done with it today.

Even a genuine SVA1032X can display garbage if you have the wrong Cal applied and some are quite delightful patterns too !
Sometimes it's best to hit Preset and reset VNA points to max which is easily accessed from the Meas menus and start all over again. SVA can take a while to get used to if you lack RF or VNA experience.

Anyways I'm working with a V5 beta and just got an update that's apparently soon to be released so I need get all my checks done with it today.

I just tried a 1-port cal again, but I turned Correction to OFF first (it always defaults on ON after power on). After the 1-port cal completes, Correction is automatically set to ON, but I get the same result. I see "---" instead of "Cor". If I toggle between Correction ON and OFF, I can see the indicator go between "---" when Correction=ON and "OFF" when Correction=OFF.

Do you think I'm still missing a step somewhere? I'm a little concerned because I would think it should work very similarly to the Open or Short cal modes. But, I'm not really where where I'm going wrong here.  :-//

EDIT: One thing I just noticed... after an Open cal which seems work work correctly, toggling between Correction ON/OFF shows clear changes in the waveform, so I know it's doing something. BUT... when I toggle Correction ON/OFF after a 1-port cal, nothing obvious seems to happen. I also tried this out by doing a 1-port cal without actually putting the OSL ends on just so I could get a pretty bad waveform... Again, toggling Corrections ON/OFF shows no difference in the waveform. It's as if it's not actually doing anything after a 1-port cal. I'm a little confused here...  |O :-//

Hi Steve,

Everything you have experienced is absolutely identical to my experience.

There are several folk going out of their way to be helpful and it is not for me to question them about whether they are using genuine SVA1032X or not but so far I am not aware of anyone with a cross flashed SVA1032X that is saying theirs works normally with respect to the 1-Port Cal routine.   i.e. those who are confident that their way of using the machine gives a proper result are all using genuine SVA1032X and so replicating their advice is not fixing the problem.

I've played around with this quite a bit now and my interpretation of events is that the one port cal is  buggy in my cross flashed SVA. There is no combination of button pressing will get you the little "Cor" label after a one port CAL.  It is necessary to follow it with an Open CAL or a Short CAL in order to do so. These latter two will of course provide you with the "Cor" label regardless of whether you did the 1 Port first. They should be superfluous with regard to a 1 port cal since the one port cal includes these CALs anyway.

The good news is that having done a 1 port CAL the machine does indeed seem to be calibrated, even though it doesn't say so.   Before a 1 port CAL with a short but fairly dodgy piece of coax attached to the port the Smith Chart seems to be all over the place with the 50 ohm load.   Afterwards, you get a nice dot in the centre of the chart with the  same 50 ohm load.

As long as you don't change the Frequency Span or any Amplitude settings the calibration seems to function well.

There are some obvious conclusions - one is that if you are serious about using the VNA for anything other than hobby educational  purposes  then you really need to buy the genuine article to feel confident.  The other is that until someone steps forward with a cross flashed SVA1032X to say that theirs works ok, it is clear that the behaviour of Cross Flashed SVAs is different to that of natural born ones (easy test - do a 1-port CAL, if the "Cor" label comes up at the end then it is behaving itself, if only -- or OFF comes up at the end of the CAL routine then it is behaving like the badly behaved cross flashed unit that Steve and I have been describing.).

Thanks everyone, for your contributions

Regards

Eloso

My unit is an upgraded SSA3021 and 1 port calibration works perfectly. I get "Cor" at the end of the procedure, I can save the calibration and subsequently restore it. If I change the frequency settings, it changes to "C?" as it should.
The only difference I see is that I am using an 85033 cal kit.

I wonder if you are masking the same mistake I was after cross flashing.
Port 1 if the TG port on the SSA, and Port 2 is the RF Port.
When doing calibration, you need to use Port 1 (TG Source).

I'll do some test on my SSA3032X+ converted to SVA1032 later on today
and will post some pics too.

WARNING:

It seems that crossflashed SVAs once in "pro mode" (hacked with no S/N) can't be correctly calibrated. That's the problem.

....  The other is that until someone steps forward with a cross flashed SVA1032X to say that theirs works ok, it is clear that the behaviour of Cross Flashed SVAs is different to that of natural born ones (easy test - do a 1-port CAL, if the "Cor" label comes up at the end then it is behaving itself, if only -- or OFF comes up at the end of the CAL routine then it is behaving like the badly behaved cross flashed unit that Steve and I have been describing.).


I had already posted previously that my cross flashed SSA3021X-plus to SVA1032X works OK. However, mine is not a 'pro-mode' conversion, it used a different technique and kept the serial number.

Can you elaborate on how you did this? The closest I've gotten was verifying that the hash key used in other siglent products matches this product by inspecting the memdump. It just seems that the algorithm used to generate the keys is different, so I'm kind of stuck on where to go. I initially started looking at this because I was wondering about adding my serial number back in and adding the appropriate keys. Any tips?

For reference, here are some tests made by an anonymous member:

Some more tests have been carried out which show that in Factory Mode the VNA exhibits quirks surrounding one port calibration function.  There are work arounds and the author has continued to use the VNA for hobby S11 measurement.  The key is in being methodical and checking the calibration status frequently by means of looking at a range of loads on the Smith Chart.

But having reapplied the serial number the VNA appears to work impeccably.

In S21 similar results were observed but the author is a little hazier on the details and doesn’t want to flip the machine between different states since this is a non-trivial task.  This is left undocumented for the moment therefore.

I would suggest that for anything other than educational use, a genuine SVA1032X should be purchased.   It is the only way to be sure of having an instrument in calibration. But for educational use only the results seem sound enough.

Hi TV84 !

did your Anonymous friend say how to restore the serial number ?
And can it be the original SSA one, or should I make one up for SVA ?
I tried the obvious places (NSP_system_info.xml), but that did not work.

Many Thanks !

The model type has nothing to do with the S/N.  You can use the SCPI command to re-insert the S/N or rollback the files that you changed.

Remember that there is a binary replica of the XML file that doesn't get updated when you manually play around with the XML.

Sum up:

1) Factory mode: implies not having a serial number, by editing/removing/deleting the respective XML file
2) With factory mode, all options are active
3) It has been found out that factory mode has bad/weird behaviour regarding VNA calibration/measurements
4) Enabling/restoring the serial number will deactivate factory mode and options need to have valid license again ("key") - cross graders will have no option at all
5) Owners of an SSA3021X+ can do the cross-grade to a SVA1032 but have to live with the mentioned issues in VNA mode if they use the factory mode to get all options activated
6) There is no public keygen

I believe there is a way:
1. We need someone with a genuine SVA1032X, to share the following files:
/usr/bin/siglent/firmdata0/NSP_system_info.xml
/usr/bin/siglent/firmdata0/NSP_sn_bandwidth.xml
/usr/bin/siglent/firmdata0/nsp_data_b1

2. Once we have those files, we should be able to change the S/N and (if needed) regenerate the licenses ...

There are several posts with a telnet loader. You'd have to connect your SSA to your LAN and then telnet to it.

Then insert a Flash Drive and copy the above files I mentioned to the flash drive.

You need to download the python keygen ...  then enter the keys as you normally would on the System Submenu ...

Since you enter the keys like real keys you would receive from Siglent, it should not have any negative impact at all ...

Not correct, read for example here: https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3180754/#msg3180754 (https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3180754/#msg3180754)
The procedure is described many times in that thread, I also wrote my version  8)
The procedure describes converting an SSA3021X-Plus in an SVA1032X and enabling all options. Obviously, you are interested only in the 2nd part. In your case it's easily and fully reversible, because you can back up the relevant files and you don't need to change the kind of instrument, nor the firmware. You only need to modify one text file and rename a couple others (perhaps a little more, I haven't fully rechecked now).
In order to make the modifications, you'll have to access the instrument with telnet: you'll find specific instructions for that in the same thread, pay attention to use the dummy firmware version for the SVA, not for the SSA, otherwise it won't run.
After that you'll have an instrument without s/n and with all options permanently enabled. After that, as maximevince said:
Quote
If you want to take it further from here, to have the correct Serial number, you'll also need a way to generate the correct license info for your specific device's Serial + Host ID.
This can be done with some help from the forum, but the procedure is not public yet.  ;)

Please do correct me if I am wrong, but for the owner of a genuine SVA who has it delivered with temporary licences (a free taster to try and encourage you to purchase the pemanent licence) then I believe there is another route.

It is possible to change the "time remaining" value in the appropriate text file and essentially keep the temporary licnce going for longer than originally intended.  If this is indeed the case, you can either Telnet in from time to time to make the change or it wouldn't seem beyond the wit of man to make this happen programmatically. Perhaps every time the SVA is switched on a script updates the file in situ with a new value.  If this indeed does work, as I understand it does with the stock SSA which also is delivered with temporary licences, then this would be a means of acheiving what you want, but without losing the serial number and any benefit in terms of stability, offered by not having to resort to factory mode.


I think as part of my history of tinkering with my machine I did do this with the SSA at one point but to be honest, having tinkered so much it has all merged into an indistinct  blur  and I didn't write everything down.  There may be other retired folk out there that recognise this particular type of memory failing. We could call it the NAND effect....    :)

Hi guys,

my unit shows exactly 100% same issue on 1-PORT calibration procedure as described by steve1515 and eloso.

If you have a look at the review of SVA1032X by The Signal Path (https://youtu.be/ToVJTKCyIU8) you can see at 33:30 of the video that his unit shows same issue of missing calibration status "---" on left top of his screen.
So, it seems to be definitely a buggy issue of the FW in pro-mode.

TauTech:
Is there any chance that Siglent could fix that in an update?
Your Smith plots for open and short condition show long "line/arc" response and not a "spot" response as should be ideal. However,  you will get clean spot result instead when using calibration menu SHORT and OPEN. The "arc" is not unusual (capacitance and inductance effects), but why not present when using SHORT and OPEN menu instead of 1-PORT calibration?

Thanks!

Not sure which exactly images are being discussed but:

Any correctly calibrated vna should display an arc on the smith chart, not a spot, for open and short standards.
This is because it is showing the true characteristics of the open or the short standard, and those are not perfect. The characterisation data for the standards are stored in the SVA, and the vna calculates it's error correction based on the difference between the cal standards you attach and the characterisation data it holds for them.

So the key with vna cals is to have accurate characterisation data for the standards you are using. If you don't use any characterisation data, then the standards are likely assumed to be perfect and you will see a spot instead of an arc. In Siglents this is the User Cal default.

Great! Would be perfect if this issue will be solved with next FW update.

My question refers to screenhots in #688 of tautech.

I know that "arcs" occure due to capacitance and inductance effects of physical connections.
However, when doing same calibration in simple "OPEN" and "SHORT" mode instead of "1-PORT" mode I get perfect nice spots.

As tv84 mentioned, all bets are off if you are using a hacked device, as the cal kit definition files might not be present.

It will not have telnet enabled.  That won't stop the normal firmware running but having got mine to where it is now by continued use of telnet, I am loath to lose this facility.   

The only means I know to re-establish telnet are to open the unit up and connect a serial cable , wait until some kind person releases a suitable script embedded in a firmware update file, or figure out how to do that yourself.  I would have liked to have been able to do this myself but information on the format of this file seems to be non existant outside of Siglent  The file may or may not be encrypted with, or use a hash produced by, a digital signature for which the private keys will be unobtainable.

I was thinking the same... but I'm not sure.
Another thing I wonder is if it would be feasible to start the telnet daemon in a different script, at an earlier level of Linux boot, one that is not overwritten by firmware updates. But I'm very reluctant to try, because I fear I could brick the system on boot. Did someone try? This would avoid losing telnet after every update.

Hi,
what I found out for a unit in Pro mode (SVA3021x+) regarding VNA calibration & firmware 3.2.2.5.0.r8.

1) 1-port cal - does not really work suffiently.
2) Enhanced response calibration is working quite well. It does not change the start & stop frequencies, nor the number of points. After a performed calibration it is saving the data internally, Calibration  on/off is only working from the enhanced response menu. This is true for a cold boot, too. Only downside you need to memorize the number of points you performed for the calibration. As soon as you apply the "right" number of points, start & stop freq., the calibration is used and showing "COR" in the upper left corner.
3) you can save calibration data as ".CAL" for example on the internal flash. When you load the data, you only need to apply points, start & stop - and again the "COR" shows up. (note them in the file name!)
4) For me it seems all preset and user Calibration Standards are not working. Port extension is not saved, either.

Post by: DL4JY on December 29, 2021, 01:36:33 pm
Hello,
one short question, if I want to measure an impedance which is not 50Ohm with VNA port one reflections, I am not in a position to change the center of my measurements (50Ohms) in the smith chart to another impedance (e.g. 1K or something else).
Due to this, I am not able to zoom in with Amplitude/Scale U to the area of the nominal impedance of my DUT if it is not 50 Ohms. Is there something I have overseen, are other VNAs able to do this ?

I could get the data via CSV - but this is not my preferred way.

thanks

Juergen

First serious error found with my crossflashed SVA1032X: (firmware 3.2.2.5.0)

After playing around for 5 days I was in the VNA mode, S11, 2 traces and switched device off.
Before I had changed „Power On“ settings and „Presets“ to „Last“.

After rebooting the system shows the VNA Smith chart but neither Power button nor any other key worked.
The system was frozen. After pulling the power plug and restarting the same situation - complete freeze!

Thanks god that I reconfigured the permanent Telnet access after the last firmware update, so I could „reboot“ the system
via Telnet and it works like expected. If you have done the update to 3.2.2.5.0 please reconfigure again the automatic start
of the Telnet daemon with the help of TV84‘s ads file.

Hi,
what I found out for a unit in Pro mode (SVA3021x+) regarding VNA calibration & firmware 3.2.2.5.0.r8.

1) 1-port cal - does not really work suffiently.
2) Enhanced response calibration is working quite well. It does not change the start & stop frequencies, nor the number of points. After a performed calibration it is saving the data internally, Calibration  on/off is only working from the enhanced response menu. This is true for a cold boot, too. Only downside you need to memorize the number of points you performed for the calibration. As soon as you apply the "right" number of points, start & stop freq., the calibration is used and showing "COR" in the upper left corner.
3) you can save calibration data as ".CAL" for example on the internal flash. When you load the data, you only need to apply points, start & stop - and again the "COR" shows up. (note them in the file name!)
4) For me it seems all preset and user Calibration Standards are not working. Port extension is not saved, either.

I want to thank electr_peter and tv84 for submitting the instruction to cross flash the SSA3021X+, nice job!

The unit I have still with firmware 3.2.2.4.0.r2 and I agree the 1-Port Cal does not work properly, but if you want to change the frequency just touch the screen where the numbers are: 100 kHz, 751, 3.2 GHz then you can change the values.

I tried the Siglent Cal Kit configurations and it seems they are working. if you try to calibrate with them you get an arc in the Smith Chart because the plane is not flush, check the calibration data in the Siglent Datasheet, in most of them the Reference Planeplane is shifted

With the User Cal I was able to make it work with Enhanced Response especially if you want to adjust the connector reference plane, but there is a trick:
- Select Cal Kit
- select User cal 1 or 2
- change at least 1 parameter,( if don't want to change anything (for example all 0) then go back one step and restore the parameter at its original value)
- go back and perform Enhanced Response Cal checking the correct User cal is selected.

if you try to change profile cal like switching from User 1 to 2, and redo Enhanced Response Cal the SVA still uses User cal 1 even if it still shows is using User cal 2. To force the VNA to load the User Cal 2 settings you need:
- Select Cal Kit
- select user cal 2
- change at least 1 parameter entering one value (example Define Open -> Delay 1s)
- go back one step
- change back the same parameter to its original value

This procedure seems to force loading the correct User Cal.

I hope this can be useful.

Hi, I am playing a bit with my new SSA crossflashed to SVA (many thanks to tv84 and other forum members  :-+).
Really newbie in the VNA world. Someone can suggest good basic course on VNA measurements (docs or videos), maybe also hands-on labs to practice?

I have a cal kit from appliedEM and I have entered and saved the cal costants in the VNA menu as User1. I have noticed that it is not possible to enter time delay and measured terminal impedance for 50 Ohm load. I can enter in the menu but I cannot digit anything. All is grey ghosted.

Is it a bug or a side effect of crossflashing? Or just a function to be implemented in the future?

Thx

Post by: DL4JY on January 08, 2022, 05:35:36 pm
indeed - changing a value of the user cal does the trick. Even with firmware 3.2.2.5.0.r8
Saving works perfectly - don't forget after loading the previously saved cal data to set all the details (start,stop & points)  and to enable it in the enhanced response menu ("appy calibration").

After a cold boot, the previously used calibration can be activated again like above described for "regular" saved calibration data with out specifying a saved file. Just activation (incl setting the boundaries) in the enhanced response menu is enough.

Now for the first time I have my open & short on spot left and right in the smith chart (r+jx) !!

cheers!

Hi, you mention 3.2.2.5.0.r8.
I have installed last month the official 3.2.2.5.0 upgrade on siglenteu.com, but I don't see r8 written anywhere, including the revision history and the system page of the analyzer...
Where does it come from?

Another short question. As I put my DIY GPSDO with OCXO (I love acronyms) circuit board into live today.
When comparing the warm Siglent SSA/SVA 1032x + with the homebrew GPSDO & very old DIY DCF 77 controlled oscillators with 10Mhz output, I see that the Siglent is of +2.15 hz - not a big deal, but ....  :)
Anybody else checked the Offset of the internal 10 Mhz ? How to enter the offset permanentely other than every time after a cold boot under Frequency/ Freq Offset ?

My self-made GPSDO with distribution amplifier feeds my SDG2042, my HP 53131a counter and now my SSA/SVA.
The reference clock will be detected automatically. It’s a pity that the SDS2000 doesn‘t have a reference clock input.

lol  spend whole afternoon to upgrade the SSA to SVA.

During the research, I found if I made the SSA3000XP enter the pro mode without cross-flashing, it still shows the VNA mode. Does that means cross-flashing is optional?

And what is the "CAT"  option?

Hi everyone. Sorry if there is this information somewhere within the topic, I was not able to find it. I'm considering buying SVA1032x for LNA design. The amplifiers will be high gain and low power so I need to have control over TG power in VNA mode. I figured out that this option was enabled with the firmware update 05/2020, but I was not able to find the specs on how much TG can be attenuated. Can somebody make a check?

I figured out that this option was enabled with the firmware update 05/2020, but I was not able to find the specs on how much TG can be attenuated. Can somebody make a check?

The VNA output can be set in the range -20 to 0 dBm at 1 dB steps and defaults to -5 dBm. If you put an additional attenuator on the reflection port and try to calibrate with -20 dBm power, you obtain a very noisy calibration of little use. One reason is the IF bandwidth fixed at 10 kHz: there is a setting, but it's still grayed with 12/2021 update 3.2.2.5, I hope they will implement it in the future. Another reason is the not exceptional dynamic range, that I think is due to the resistive bridge design (not coupler-based).

Post by: DL4JY on March 06, 2022, 02:35:14 pm
Hi,
I am thinking about assumed low sensitivity of resistive bridges compared to couplers.
To my understanding has a pure resistive bridge with 50 Ohm resistors (one is the device under test) a nominal attenuation of 12dB. With the benefit of a high bandwidth and a low cut-off frequency. Couplers would start at higher frequencies and have at least a sensitivity in the same region. Do I miss there something?

I believe, too - (as mentioned) - a reduced bandwidth (RBW) would increase the usable measuring range (dynamic) . The minimum RBW for the SA with Tracking generator is 30hz, probably for ensuring that the SA-Receiver Frequency is matching the SA Transmitter (Tracking generator) & the sweeping speed is not to low. That would result in 25dB more dynamic range.

Maybe somebody at Siglent could take this topic and check if it would be feasible for implementation in an upcoming firmware release.

Regards,

Juergen

I encountered my first serious issue with my SVA1032x. I am not sure if I had too many calibrations saved, but for whatever reason, none of my calibrations were working and a few times the unit would power up and the spectrum analyzer had no reading. It wasn't until I did a factory reset that it started working properly again.  I usually unplug it every time I am done with it because our power company has had numerous power surges.  I hope I don't have issues when the memory battery goes dead...

Did Factory Reset retain your Cal files ? IIRC they should still be in the internal memory.
Can you still load them ?

And FW version please.

Certainly and you can also activate a total of 4 traces showing Log Mag, SWR, Smith and Phase.
Have a study here:

Some further stuff here:
https://www.eevblog.com/forum/rf-microwave/antenna-project-log/ (https://www.eevblog.com/forum/rf-microwave/antenna-project-log/)

With recent FW the max points has been increased to 10001 from 751. Default is still 201.

Well, not straight out of the box: I have just double-checked, but in mine (fw 3.2.2.5.0) there isn't a resistance plot; besides, frequency scale is only linear.
You should select Smith display with subselection R+jX, then export as CSV. You will obtain a file like the following, where only a few lines are shown, total 751 frequencies in this case. You can then import the file in a spreadsheet and plot R (second column) vs f as you like.
I also see that in your example the measurement range is in the milliohms: it seems a plot of series resonance of a ceramic capacitor. This is not feasible with a decent accuracy with a straight one-port measurement. It could be reasonably possible with an S21 measurement on a special fixture holding the component (on a proper position, shunting to GND) and some post-processing of the results; but I'm not sure about the achievable accuracy with this instrument. Full 2-port measurements may be required to get the best results.

Now I am second guessing myself. I cannot remember if I hit "Factory Reset" or "Reset & Clear".  Whatever I hit cleared all of my saved calibrations. I had dozens for various cables, connectors and frequency spans. All gone.   I will have to periodically save them to USB as I create them.

Did Factory Reset retain your Cal files ? IIRC they should still be in the internal memory.
Can you still load them ?

Yes I had that problem with saved Cals too after upgrading FW versions and I see you are still on V4.0.
V5.0 is available here:

Hi,

I'm considering getting an SSA30xxX Plus to hack to an SVA. Are the SSA 3015X+ and SSA3021X+ the same HW, do they both hack to an SVA3032? Where is the dividing line in the HW?

The 3015 will only be a SVA1015. The 3021 will get you a SVA1032. That's the line.

So the 3015 is it's own thing, but I think there is another line then that is above the 3032. But I think those are out of reach for me, sounds like the 3021 is my starting point.

Careful study of the SSA3kX+ and SVA1kX datasheets reveals which models might share the same HW.  ;)

I'm considering a SVA1032X but I'd like to get an impedance vs freq plot log/log similar to the example below.  Is that possible with this?  Is it available with other instruments?

Like a @RoV say, first export smith chart to csv. Import to excel and in new columns you can calculate impedance and phase.
For first data row:
impedance: =SQRT(B14*B14+C14*C14)
phase: =ATAN(C14/B14)*180/PI()

Next you can create good charts with XY scatter type (logaritm is supported)

If you plan logarithmic scale, set VNA to log scale before exporting - this will give you more detail at the begining of band.

I hope that in near future this math can be implemented into device and we can plot impedance graph directly.

Hi
    I have purchased a SVA1015X from the Telonic in the UK.  I must say I am extremely unlucky.  The first unit had both dead TG and VNA right out of the box. I sent it back to Telonic. However the engineer at Telonic checked it, both TG and VNA are working again but I refused to take it back. This morning I received the replacement unit, I had got a frozen black screen when I first powered it up. The unit was not responding to any touch of the buttons (preset, display, ESC etc) or touchscreen. The TG and mode buttons were both lit up. In addition, the green LED light of the LAN port lit up even I didn't connect it to any LAN cable. I turned it on and off two times, the unit starts working again. I captured the malfunction event with video recording and sent it to Telonic. Both VNA and TG are working now. From the system log, it shows "SIG_NOT_STB"

According to Siglent user manual  (25) SIG_NOT_STB= "Signal is not stable enough to track". Also it states in the user manual "(1) Check whether the fan is running while the screen is dark, maybe the LCD cable is loose?"
 Well it does not make any sense to me. Initially I thought it might have a loose ribbon cable connected to the LCD screen due to shocks during transportation. But those ribbon cable has a mini lock and should not come loose easily due to vibration. (The parcel driver handled the box very roughly and punched a hole on the top of the box. Siglent should ship their products with double-boxes like Rigol.)

     I have spoken to Telonic engineer, he said he will contact Siglent about the issue. I have been told to monitor the unit in case it happens again. I wonder anyone here had encountered a similar experience? For my peace of mind, I will have 3 years warranty. But two problematic units in a row, what bad patch is this? |O |O

In addition, I found the calibration menu a bit confusing. It only has Open, Short and Response with Load option missing. The only way to calibrate it with 50 ohm load is to go to 1-port Cal which is designed for reflection S11. So if I want to do S21 calibration, I can miss the calibration with 50 ohm completely. I have owned the NanoVNA V2, NanVNA V2 plus 4 and NanoVNA F. I found it quite odd with the omission of "load" in the top level calibration menu. Any idea why?

Post by: regenfreak on April 21, 2022, 06:40:02 pm
I have found the calibration menu rather clunky and not intuitive compared with all of the NanoVNA models. For S21 measurement, the calibration step with a 50 ohm load can be skipped. I always thought it is necessarily to do 50 ohm load calibration in S21? :-\ Now I can do Open, Short and Response Through with or without doing the "Port 1 Cal that requires the use of 50 ohm load". When I turned the Port 1 Cal on and off, I get slightly different responses. Also I have compared the results with my NanoVNA SAA-2 V2(see attachments),  while the S11 and S21 are fairly close, but the Smith charts are very different. The attached photo is the sweep of a homebrew filter. Also the * symbol that shows the completion of calibration is inconsistent. Sometimes * does not appear even I complete and confirm the calibration on the touch screen prompt. It is so easy to display four traces with the NanoVNA while it takes me a couple of steps to display multiple traces with the SVA1015X.

OK, for S11 measurement, we have to use port 1 Cal and then save the trace. This requires open, short and load. The calibration menu looks confusing because it has open and short beside the port 1 cal (which also has open, short and load in the sub menu).

For S21 measurement, only through calibration is needed. This raises the question why Siglent introduces two sets of open and short menu buttons? ??? Now I don't know if S11 and S21 can be measured simultaneously with SVA1015X like the NanoVNAs. It may need independent calibrations and measurements for S11,S21, Smith chart and SWR separately like the Rigol VNA in the link below. I have got this information from the Tek VNA and HP manuals:

https://download.tek.com/document/70W_60918_0_Tek_VNA_PR.pdf (https://download.tek.com/document/70W_60918_0_Tek_VNA_PR.pdf)

http://web.ecs.baylor.edu/faculty/baylis/eel4421/Procedure7.pdf (http://web.ecs.baylor.edu/faculty/baylis/eel4421/Procedure7.pdf)

and also Rigol VNA demo:

https://youtu.be/ptXTblLFUBc (https://youtu.be/ptXTblLFUBc)

My Smith charts look different because there are many Smith chart axis options in the SVA1015X. In the NanoVNA, it shows real and imag.


There are actually many powerfully features in the SVA1015X. From now on, I will have to develop a new mindset adapting to the more advanced features.

The Open and Short top level options are actual calibrations in their own right.
They are not related to the Open and Short steps in an OSL calibration.

The idea is that you can do a rough cal with just one standard.

Post by: regenfreak on April 21, 2022, 09:36:51 pm
yes i have just noticed that. If i do port 1 calibration first and repeat open cal, it will overwrite port 1 calibration. So does short cal, it will overwrite open cal. I dont see the point of having this menu design. A half-arsed calibration like that has no real value in a proper characterisation of DUT.

It is just a way of providing a fast calibration.
Saves on cal kit wear and is also implemented on Keysight gear.
https://na.support.keysight.com/pna/help/latest/S3_Cals/Select_Cal.htm#openshort

I just turned my SSA on and did an open cal with the port open, and then put on a load. It was < 30dB up to almost 7GHz.

So certainly useable for measuring an antenna for example.

I see. It makes more sense now.
It will take some time for me getting used to the menu. It is interesting to read how about old, mega expensive VNAs (one of those still uses floppy disc) are calibrated.

I am flabbergasted and depressed. |O The new replacement unit has developed intermittent faults after two days of testing (on top of the black screen problem when i first powered it up :-BROKE.)  It was working fine until today that I have encountered repeated occurrence of these weird faults many times (all random):

1. The Smith Chart is very noisy before after and calibration. The traces are jumping around across the screen after calibration when it is open or with a 50 ohm load (see screen shot of the video). The noise is bad sweeping from 10MHz to 1.5G. It looks more horrible at lower frequency.  I switched it on and off, sometimes it is very noisy and sometimes it is normal. I  checked the connectors and calibration standards with NanoVNAs. The SMA adaptors  are all fully tightened.

2. The TG and VNA are intermittently not working, completely unresponsive ,only showing the noise floor (this was the same issue with the first unit)

I made a number of videos that show the faults as evidence, in case Telonic think I make it up.

The attached images show the results when the unit was working:
 (a) Wes Hayward's di-directional amplifier from 100k to 30MHz vs NanoVNA V2, it shows correct response down to about 2.5MHz which is OK.
(b) 467Mhz cavity bandpass filter
(c) A chinese 20db low noise amplifier

When it works, it is great. When it plays up, I am pulling my hair out.

Start from basics to confirm:

Do a factory reset.
Disconnect everything
Do an Open Cal with nothing on the port. Dont use your open standard.
Attach a load and show the S11 trace screenshot.
If that is inconsistant then either your load standard is faulty or its dirty, or the device is faulty.

The noisy traces happen when there is NOTHING attached to the VNA before and after calibration. I have to switch the unit on and off whenever it happens.  I have three NanoVNAs and have tested three sets of calibration standards. This problem has happened even I use different sets of calibration standards. I am 100% it is nothing to do with the calibration standards because I have checked them with my NanoVNAs doing side by side comparison. The SMA-N adaptors are new, and I have looked at the connectors under microscope, they are perfectly fine. I have a few videos proof showing this random fault happening so no one can blame the  calibration standards. I feel very stupid when the second unit seems to be a lemon too. Do they have a bad batch?

If you look carefully at the screenshot of the video, there is nothing connected to the port. The noisy traces are like flying sparks from a tesla coil! |O

The response at the low freq end of the SVA devices was poor, and so you could just be seeing the low freq 'tail' of the smith chart jumping around.
You have already noted it is fine above 2.5MHz. Below that it will bounce around on the Smith chart. So start the sweep at 2.5Mhz and see what happens.
This spec was improved in the newer units, but I don't believe it is great. I don't have one to try and replicate.

Other points:
You need to simplify things and start from a known base. This is troubleshooting 101.
Switch to LogMag images only for now, it is much easier to look at and interpret.
Factory reset is not the same as turning it off and on. You really need to factory reset before reporting a fault so that others can replicate the issue.
You're testing active devices, so perhaps you reduced the TG output level? This could be making the S11 low freq response worse.
It is hard work to follow your pictures, there is too much going on, too many traces. 
Your DUT's are too complex. If you want to demonstrate a fault with the unit then test something simple with a known response - like an attenuator or a load.
The marker colours are not matching either - which appears to be a screenshot bug worth reporting.
Have you checked to see if you are using the latest firmware?
Also, I have a set of new N-SMA adapters which I think I got from MiniCircuits which look clean and perfect but cause problems. But agree, not likely a problem at 1MHz.

Factory reset. One trace per picture. Start with the simplest calibration possible and then measure some VERY simple device.
Simple device would be an attenuator if you have one, or a load.
Ideally make a video showing these steps, if it shows an issue then stick it up on Youtube for us to review. Then if we can't solve it we can send it direct to the Siglent engineers.

You may well be correct and the device could well be faulty.
But you could also be suffering from confirmation bias caused to the frustration of having so many problems.

You misunderstood my post. It is easier to show the problems with the youtube videos:

Noisy Smith chart:
https://youtu.be/t-wb9Cz4c1s

Black screen problem:
https://youtu.be/xJvOhKnAI1U


The unit is working normally and correctly most of the time except. I encountered the intermittent problems with noisy Smith chart even i don't attach any DUT to it before and after calibration. The examples I posted are correct. I have not complained about the measurements! They are not complicated, just S11, S21, Smith chart and SWR. It is very useful and meaningful  to look at them by-to-side. They all make sense to me but maybe most people avoid Smith chart.  Of course it has the latest firmware and i did preset many times. Remember i have had the unit only two days.

I think the TG and VNA are OK.

Thanks, it helps to have the video. The text is unreadable, so your words are very important.
Your measurements make sense to you, but if you were on my side looking at your screenshots you would understand.
The confusing thing is some of the information in your screenshots (S21) is correct and matches the NanoVNA.

You state in the video the default start freq is 5MHz - is that correct? I thought it was 100kHz from your screenshots?
This is a big difference and does make it look like a fault with S11 only.
Can you show an image or video of it working correctly for comparison?

Would you please show a video of the following:
Factory Reset.
One port cal.
Then take the load off the port.
If you can do it so the text is readable, and the screen and ports are visible then that would be most helpful to the engineers.

No information on firmware version?

Ok I watched the video more closely.

The first time you did the 1 port cal you used the 50 ohm load for the short and the load.
Short/Load:

The second time you did it correctly.

It is nothing to do with the calibration.  You cannot explain why the Smith chart is so noisy before I attached anything to unit! Can't you see how quiet the NanVNA is?  I did it three times in the video. It only worked after i switched it off in the third time.

I have the black screen problem again this morning:

Another demo of the problem. This time I tightened the 50 ohm load with an expensive SMA torque wrench:

The use of torque wrench is an overkill for quick test like this.

Well I can only comment on what you show me, and that was a clear cut operator error which explained the results perfectly.

The calibration is one problem. It _does not mean_ the device is completely fine and I did not say that!
Here are the other issues that I can see:
The black screen is a problem.
The default calibration after factory reset should be much better than what your video shows. This could be because the device is set to Last or to a User config on Power On/Preset, and a bad cal has been saved.
And there appears to be a bug in the screenshot trace colours.
- There still may be a random tail flicking around if you set the start freq low enough though. I can't compare as I don't have a device.
The NanoVNA will be better in this regard as it does not have magnetics in its bridge.

So the first two things I would do are a Factory reset to eliminate any possibility of corrupt settings and remove any saved calibration (which will be restored after preset/power on if set by the user)
And a check of the firmware version and an upgrade if necessary.
There have been many bugs found and fixed.
The torque wrench is not required and is not the problem, but FWIW you are not using it correctly. The calibrated torque will only apply if your hand is at the line on the handle.

Aside from that I don't think there is anything else I can do to help.

I would return the second unit and ask for a full refund.

I would then buy the SSA3021X+ and read this thread from the beginning.

If the second unit is still working weird with black screens and strange behaviour, you are certainly entitled to just send it back for a full refund. No point trying this and that, doing a factory reset, etc. This device should work fine out of the box.

Yes, finally I have got a sympathetic answer. I have not changed the factory settings or messed around with the default display or power settings. I always press preset which resets it to factory settings. It should not happen, full stop. This video shows another black frozen screen problem, I have to cut the power and switch it off. I will return it and ask for a refund. I was going to buy the SSA3021X+ but I made a wrong decision going for the VNA and SA hybrid. I really like the VNA when is working but I am completely put off by the intermittent problems.

you are wrong I am afraid. Please watch 55s. At 1:00 I transferred the load from NanoVNA to Siglent VNA. At 1.25s I incorrectly said it is registered open, it should be short.  Also you ignore all evidence presented to you . There are lots of noisy traces flying across  the Smith chart. You are wrong to assume the load is longer than others. My load is quite short.

You try to tell me I cannot tell what is a 50 ohm load?  Come on. I have both long and short 50 ohm loads. Anyone who has used a VNA would notice that  the traces should not fly across  the screen like that without or with calibration.

The hint was that you can hack a SSA3021X+ (the plus model) into a SVA1032.
It will cost you little more money than the SVA1015X. I guess this model is not sold much anymore...

I would never do that. I do not want to waive my warranty. So far those cheap NanoVNAs can do the same measurements as SVA1015x. I must say I really like SVA1015X when it is working but I have packed it up.

 I dont want to spend another minute thinking about it or try to argue about it.

Ok I watched the video more closely.

The first time you did the 1 port cal you used the 50 ohm load for the short and the load.
Short/Load:
https://youtu.be/t-wb9Cz4c1s?t=181
The second time you did it correctly.

That is why it worked the second time and not the first.

you are wrong I am afraid. Please watch 55s. At 1:00 I transferred the load from NanoVNA to Siglent VNA. At 1.25s I incorrectly said it is registered open, it should be short.  Also you ignore all evidence presented to you . There are lots of noisy traces flying across  the Smith chart. You are wrong to assume the load is longer than others. My load is quite short.

You try to tell me I cannot tell what is a 50 ohm load?  Come on. I have both long and short 50 ohm loads. Anyone who has used a VNA would notice that  the traces should not fly across  the screen like that without or with calibration.

Actually I am correct. You did confuse them, and i simply pointed it out, because that will cause the problem you are seeing.

Then you posted another video later where you do demonstrate the problem. This is the one you are talking about.

I'm actually not arguing with you, i am trying to help you to be sure it is faulty before you go through the hassle of sending it back again.

Anyway. Whatever happens, all the best, I have done all I can.

Just a note of encouragement. Like you, I have a few Siglent bits of kit - A scope, the SVA3021X (started life as the SSA model), a SDM3055M and a power supply.  All from Telonic.

In all cases, happy as larry  :) apart from the Bench DMM.   That was a bit of a saga - I bought the 3045X then sent it back because of the relay design fault in order to exchange for a 3055  (all mentioned elsewhere) which when it arrived had a marginal kind of fault - one of the 4mm sockets was a bit rough and the probes didn't feel quite right when pushing into that one.  All of this kit cost much hard earned cash of course and although I  got a gentle comment back saying that the probes went in ok and there wasn't much wrong, as far as I was concerned it wasn't a £10 meter from Aliexpress, and I expected better. These instruments will last me a long time (and I will be buying more stuff from that supplier) and I like to feel good about this kind of purchase, not feel a pang of regret every time I switch it on.   So to their credit, the supplier sent me a new 3055 and now all is well.

If your VNA isn't right I am sure you are doing the right thing in rejecting it whether you decide to get another one or not.  I am sure Telonic will do the right thing (do let us know either way - its good to reward good businesses and personal recommendations on these forums do help them I am sure).  Eventually you will have the kit that you want and all the hassles of backwards and forwards / phone calls, emails and videos will be just a memory !).

Regards


Eloso

p.s. if you didn't buy it as a commercial customer, then don't forget there are distance selling regulations in the UK  that allow you to return goods within a certain time period without actually needing to prove them faulty.  I can't remember the exact laws now - they changed a little while back but a quick google will come up with it.  I am sure Telonic will be helpful though in any case.

This is from a web site:

The Consumer Rights Act 2015 provides that goods must be of satisfactory quality.

This means goods must be suitably durable – meaning they should last for a reasonable period of time and should be free from fault.

Where goods fail to meet this standard, the consumer will always have a remedy. This remedy will be an entitlement to a full refund if the fault is discovered within the first 30 days after purchase or ­delivery or a free repair, replacement or refund – the trader gets to chose which one – if the fault is discovered after 30 days.


In my case, I have not misused, modified or hacked the product. I have provided video evidence to show the faults. On the morning I received the unit, I tested it and sent their engineer the video of the black screen fault right out of the box in the afternoon. I should be able to get a refund. I take no pleasure in finding faults in product. It is not a good feeling when you are on the receiving end of it.  If i spent my hard-earned money on a £1500 product, I expect it working right out of the box. I should not be blamed or expected to do factory reset, messing around it if it does not work. I dont have time for those kind of nonsense.

Telonic sells on ebay UK and it gives extra layers of protection by both ebay and paypal. This time I ordered directly from their web site because I wanted £20 before midday delivery option which is not available on ebay. I must say my local APC driver is awful. Both SVA1015X units'  boxes were damaged during shipments. Are they tossing them like footballs?

I have the same issues with the SVA1032.
The smith chart is very noisy and short/load/open are not described as points in the log smith chart view.
I use a professional calibration kit.

Another thing, when i want to specify my cal-kit under user cal. I cannot enter the specific details of the load ( it is grayed out as being exactly 50 ohm, which is not ). All other can be specified.

Does anyone has a clue?

I think your N-type to SMA adapter that you are using on the SVA is worn out.  Also, you cannot change frequency/span after a 1-port cal Notice the little "C?" in the corner of all your screenshots? That means it is not calibrated.  You cannot change any of the settings after calibration, not the frequency, not the number of points, not the TG level, none of it.  That is why it gives you the ability to save calibrations, so you can go back and load a previous calibration for a previous frequency range etc. 

After seeing you fiddle with that short and watching it jump around, I would suggest going on RFParts.com or another reputable site and getting quality N to SMA adapters (and port savers).  If you have an intermittent contact during calibration, which I can almost guarantee you did regardless of how tight it was, it will have that very effect.  I can see they are clean connectors, but if you have to play with it to get a stable reading, its shot. 

Also, in this video at the 2 minute mark, you see how the load temporarily made contact then dropped out again when you were attaching it? There you go right there, shot.  You essentially did the load calibration with an open :) GET NEW ADAPTERS!!!!!

The SMA adaptors are completely new. One of them come with the SVA1015X free RF connector  kit from Telonic. The other one is newly purchased. I checked them under microscope, nothing wrong with them. The contact pins are as straight as Nelson's Column in Trafagar Square.  No one here in the forum can come up with a rational explanation why the noise goes away if i switch the unit power off and on. It is all intermittent and random.

The chief engineer from Telonic saw my videos and he thinks my unit is faulty too. I  returned it yesterday getting a full refund. He will report the issues to Siglent. I feel vindicated and happy as I am suddenly £1500 richer.

I am more than happy sticking with my Nanovna V2 plus 4, NanoVNA V2 F and SAA2 v2. The Nanovna V2 plus 4 has the dynamic range of 90db vs 75db with the SVA1015X. I have to reiterate that the SVA1015X is a great machine but it is 10x times the price of the NanoVNA V2 plus 4; 3 x times the price of the LibreVNA (which has the dynamic range of 95db, 6GMhz, plus S22, S12 measurements!).

Actually I repeated many times afterwards (not in this video). The noisy Smith chart is random and intermittent. You cannot simply tell  based on this particular video.  Anyway Telonic engineer has said it is faulty, then it is faulty, end of the discussion. :horse:

I have the SVA1032x (not hacked, not molested in any way) and I can tell you that what I saw during your calibration was an internittent contact.  During the calibration, attaching the short and load will change the trace (even though it down not necessarily stay on the chart until cal is finished). You saw it yourself, an unstable reading while attaching the short (which became stable when you played with it), and an unstable reading while attaching the load (which you totally missed). 

Furthermore, Telonic is not the originating company, they are just a certified dealer. There is no way to know if your "free" adapters were decent or if they are cheapest ones China can offer (leaning towards the latter). 

The male's pin can be straight as a laser beam, in fact, that makes it worse, because when the female's hole stretches open, the male's pin barely touches. When you hit enter with that load attached, it wasn't touching, and that was clearly evident in the video. So, why does it jump around so much, easy....  You told it that an open circuit was 50Ω, and therefore, it put that open at the center.  Now, as any VNA user can attest, these things rapidly lose accuracy as the impedance gets higher than about 1kΩ, so as it tries to extrapolate the impedances between the open in the middle and the open on the chart, that entire range is in the VNA's unstable territory.  Just entertain me and try a different adapter, what do you have to lose?  You can drop $3400 on a piece of test gear but want to avoid spending $20 on a decent adapter???? Good luck with that!

PS. What is wrong with the RF test connectors from Telonic and ebay? They are made in China but the SVA1015X is also made in China.

Case in point, I did a calibration on my perfectly working VNA. I used nothing as the open, jiggled the short during the short sweep, and used again nothing as the load. This is what i get after calibration (except I used 3000 points, not a couple hundred).  Same result you get!

For a bad connection, yes, that is normal. With the tech returning it to you stating that it was fine, with the obvious bad connection in your video, and with me showing how to replicate your results by simulating a bad connection, and you still think that $1 connector is good...  I have no further comment either ~ except one.  I'm sorry to hear you had such trouble and I hope that you eventually find a good VNA that works for you.

I can simulate a bad connection by loosing the connectors or turning the connectors with any VNA.  When a symptom is  the same as a bad connector, it  does not automatically  imply it is 100% a bad connection.  The cause and effect are not 100%  correlated.

Right, but before going in for a chemotherapy or a brain transplant, you first look at your caffeine intake, pop an aspirin, check for TMJ or ear infections and see if the thyroid glands are swollen.  I was suggesting trying a different adapter, you opted for the transplant...

@regenfreak,

 You did the only sensible thing you could have done in this circumstance. @antenna is right in a way but he's forgetting the other ten SMA connections and their five patch cables inside the SVA as pictured here:

https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3088340/#msg3088340 (https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3088340/#msg3088340)

 When I saw your plots, it put me in mind of techneut's experience after cross-flashing his SSA to an SVA, hence my guessing from the symptoms you'd described that the fault was very likely one of these internal connections (a loose or damaged connector or faulty patch cable).

 Regardless of the actual cause, the problem was obviously a fault within the SVA itself (the black screen events were enough cause in themselves to justify a return).

 Telonic, when convinced that you have reasonable cause to reject the goods as faulty, will respond to such requests without undue delay, even when it means they have to bear the cost of collect and return. TBH, I was wondering just when you were going to request a return with full refund, hence my "vote of thanks" when you finally did so :).

Thank you! Exactly!  Lots of hardware components can go wrong and not just the loose cable connections. It could be the digital switch, voltage regulator ..etc It could be just one capacitor shorted, a cold solder joint..A spectrum analyzer is an extremely complex equipment. I subscribed to this guy's channel with the link below, you will see countless examples of failure due to one single shorted capacitor or mosfet:

https://www.youtube.com/c/NorthridgeFix/videos (https://www.youtube.com/c/NorthridgeFix/videos)

Only the Siglent factory technician can have the right  diagnostic tools and expertise to find the issue. An Average Joe like myself can only make unsubstantiated speculations. It is not smart to do a hard factory reset as it would simply wipe off all the existing messages in the system info log. I could see what date the quality control technician connected the unit for checks in the log. In the log, there is a  system message appeared at very moment I powered it up the first time with the black screen problem. It is not my job to decipher what it means.

If you watch Mark Jones' teardown video, you can see the directional coupler is integrated within the tracking generator.  The simple,  low-cost design probably explain its rather lacklustre frequency performance of 5MHz to 1.5GHz. The big touchscreen and user interface are great. I am not bashing the SVA1015X.  I would definitely keep it if I had not encountered those frustrating black screen and noisy Smith chart issues. Murphy's Law hit me with two strikes!

I don't disagree with the last few posts, and in my defense, seeing the screenshots of it working (and uncalibrated), I figured the black screen thing was resolved (and that rudimentary mistakes were being made).  But one thing is for sure, that short stabilized when fiddled with and nobody can deny that when the load was screwed on, it started to respond then it went away once the SMA load was tightened (and straightened). To me, those occurrences say the female end of that adapter was in the same condition as my last girlfriend.  But what do I know, it's not like I ever had a cheap non-teflon connector spread its cheap plastic insulation allowing the female center to widen... Nope. Not once.  All I did was make an observation and suggested trying a better adapter.  Apologies for that and not realizing the black screen was still an issue.  Next time, I'll read more carefully.

Yep, of course and it's very likely the inbuilt bridge was swapped out however if you hunt through the datasheet there are still a # of differences to the 3.2 GHz model including weight = lesser HW.  ;)

But when the # of VNA data points are wrong by an order of magnitude it screams someone is not doing their job !  :horse:

Quick question if I may,

Since I use my now liberated SVA1032X only for hobby purposes I'm not in the market for a professional mechanical calibration kit but for something slightly nicer then the average AliExpress stuff. I found a fairly economical mechanical calibration kit, made of Rosenberg SMA parts, on SDR-kits.net

The kit comes with calibration instructions from Kurt Poulsen OZ7OU, are made with the best intentions but not the easiest to understand for me.

The idea is to enter the female cal kit parameters under Calibration>cal Kit>User1 and the male cal kit parameters under User2
I can enter the "define open" delay of 42.3ps and no need to change C0, C1, C2 or C3 so that's all ok. But when I try to enter the "define Load" parameters the delay and Terminal Impedance fields are greyed out and there are no fields for C0, C1, etc, while the kit comes with a measured terminal impedance and the instructions to define CII as 5pf.

Any idea how I can enter the calibration parameters?

You can't change the impedance of the load on the SVA. I think the greyed out options are saying 'not yet implemented'
Therefore the load is assumed to be 50ohms for a user entered cal kit.

As an aside, for the pre-defined cal kits I believe that data files are used instead of a C0,C1,C2 etc parametric model.
But there is no built in way for an end user to use that system for a user defined cal kit.

The only way to use all of the provided params is to export the sweep data to a PC and do the calibration there.

I was using my SVA1032X and found when I turn on min/max or averaging traces there is no way to "reset" the traces which makes it hard to connect probe and then start the min/max, has anyone else seen this, am I missing something?

Additionally I found that there is no way to freeze screen, ie stop.  For example I am probing with min/max on and then need to release the probe and save waveform, but it does not appear I can do this. Anyone have suggestions on how to stop and freeze the system?

I am also looking at trying to do impedance measurements with the SVA, it looks like it should be possible and was wondering if anyone has done this and might have a python scripts for such a feature?

Thanks

When I want to reset, I just tap "Clear Write" and then go back to max or min or average.  If you tap "view" (underneath Min Hold in the trace options), that holds the screen as is and allows you to release the probe and do whatever.

And, of course, it does do impedance measurements...  Just press the mode button (one of only two made of transparent silicone, although I've never seen it lit up green like the TG button) and select "vector network analyzer". Be sure to do your calibration though.

You're overlooking the type of trace required/selected for each task and the type of detection required.

In the Trace menu use the View option that ceases the sweep and freezes the trace, permanently until you select one of the other Trace options or reclick on the type you were using to start the sweep again.

Below is a quick selection of screenshots displaying some various menus showing preferred settings and some captures of 100-120 MHz 0dB sinewaves from my SDG6022X
Trace A is the only one not displaying it was 10x averaged and Trace B was to be Max Hold but I must have made some error.  >:(

Hope these are of help to get you better acquainted with the capability of the SVA's.

Thanks for the information!

I am still learning about RF and using the VNA. 
I wanted to measure the impedance of piezo probe.  So I setup the VNA on S11, Smith chart R+jX, and got the enclosed smith chart.
[attachimg=1]
I then saved the CSV and created a linear graph.   
[attachimg=2]
This was not what I was expecting so I connected up a MSO5354 scope and did the measurements using a reference resistor.
[attachimg=3]
I did not calibrate the system, but the curve shape matches what I was expecting.  Note using another resistor as reference shows that the measurement has some frequency error most likely due to the cables I am using, but the curve shape matches my expectations.
[attachimg=4]
I was wondering if anyone had a reason that the VNA would not be giving me a similar impedance curve?   

Thanks

The two curves are not so different... did you calibrate the VNA? In case you didn't, is it a true SVA1032 or an upgraded SSA? I ask because the SVA1032 has a builtin calibration that I expect to work acceptably well at such low frequencies, unless you use very long cables; on the contrary, the SSA normally doesn't have it and the error can be very large.

It is a SSA3021X plus hack/upgrade and I did calibrate with short/open/50 Ohm load.   I also tested the VNA with 100 ohm and 50 ohm resistors to make sure the impedance was reasonable.

The frequency range is up to 10Mhz, hence the cabling will make a small difference but using 6" SMA RG316, I doubt it is significant.

I actually got the magnitude and phase graphed, for the VNA: [attachimg=1]

I also have it done with an O-scope and signal generator. [attachimg=2]
Forgive me for not labeling axis on graphs. The phase Y axis is degrees, the X axis is frequency in Hertz.

This is the same piezo element.  I estimate the scope could be as much as 6 ohms & 12 degrees off based on running a test with a 50 ohm load. The o-scope is done with BNC alligator cables which have more capacitance.   

One of the things with the piezo is looking for the resonate frequency, which is typically the point where the phase is closest to zero.  In the O-scope version this matches what I was expecting and is at ~8.25Mhz, while the VNA shows to be at 8.5Mhz which is a significant difference.   A second issue I wonder about is that from what I have read the resonance frequency should have the lowest impedance, which does not match the data. 

I guess the next thing is to create some known complex impedances and measure them, like an RLC circuit.   

Overall it is a blast to learn new things, and I am having great fun.

Not yet: option is present under the STIMULUS menu, but fixed (grayed) at 10 kHz on the SVA1032X with FW V3.2.2.5.1R1, and I imagine is same is true for the 1015.

I have simulated a simple resonator model, series RLC plus a shunt capacitance, normally used for piezos close to resonance. I have tuned the component values to get an S11 shape similar to yours. The Z11 resembles more your scope plot rather than your VNA Z plot, so I suspect you made some mistake in the S to Z transform.

The external capacitive loading lowers the resonance frequency. In the case of the VNA it is compensated by the calibration, so there is no excess capacitance if you calibrated on the DUT plane. In the case of the scope you may have a few 10s to 100 pF of additional shunt capacitance.

The series RLC1 block has a minimum real impedance of R at the series resonance frequency of the intrinsic resonator, but, due to the presence of C1, phase is a bit negative there, around -47°, and the real part of impedance is slightly lower than R. In this specific case phase reaches the minimum of -9° at an higher frequency, where R is transformed to an higher value.

I recently purchased a fresh SSA3021X+ that is now a newly minted SVA1032X so I'm pretty happy about that.

I was able to borrow a decent Spinner 3.5mm cal kit, add it, calibrate, and get a good calibration on the VNA portion and do some simple measurements.

I'm looking at purchasing my own (cheaper) cal kit and figured the Siglent ones were a good place to start. I've almost settled on the F603FE as a good budget compromise but I was wondering where exactly the calibration coefficients (or CSV for S-parameters?) stored for these kits? Mostly interested since all the other kits I've used in work (some Spinners and some Maury Microwave kits) come with the coefficients or the data files to load versus having it already in the system.

I found the /usr/bin/siglent/usr/vnacalkitdata but it seems to be a sort of mix of different standards and if I'm reading the .csv right, all of mine end at 1.5GHz? Is there another spot that I can't seem to find or is this an artifact of the conversion process to the SVA? Just wanted to make sure before I purchase I won't end up with a weird half-way there calibration setup.

Okay chaps, I may have found a bug.  :scared:

SVA1032X
VNA mode, Mag Loss.
Save a TRC (Trace) file to be used as a reference trace so to be recalled which these instruments if we are to believe the user manual can do.
https://int.siglent.com/u_file/document/SSA_XP_SVA_UserManual_UG0703P_E02A.pdf
8.3 File P139

First screenshot is how I want to use a stored TRC file, that is display it from memory to compare with a live/active trace.
Can't seem to make it work and save a TRC file to internal or USB memory.
TRC is not always available to select as a Save or View filetype.
Is it Mode dependant ? If so why ?

Unreasonable expectation, I don't think so. Opinions please ?

Are you using the same start/stop frequencies and number of points? If these are different it only makes sense that the saved file won't open.

I don't own this device, so I can't test, but my own software uses a similar feature with this exact limitation

Can your older SSA3kX save and recall a TRC (Trace) file ? That's the only issue this end.
Once recalled according to the manual it will be displayed at the settings when saved.

The screenshot only shows why I need to recall a previous trace so to compare any previous measurement against a live one.
This feature seems not to work as one would imagine and it needs be sorted especially for the portable SHA800A coming as this will be used in the field with such a device.

It seems to work fine on mine. The yellow trace shows the TG dirrectly connected to the input with normalization.


You can now compare both traces.

I think you assumed that the TRC file will be like a background image - that is not the case. It is read as a trace and obviously kept in VIEW mode (otherwise the sweep would overwrite it).
When loading the TRC, it will set the relevant START/STOP frequencies, as I expected.

Thank Vitor and yes I can save a TRC file in SA mode. It's been on my mind for most of the day and your post kicked me into trying it.
200MHz sinewave from SDG6022X saved as a TRC, reloaded onto display and trace B enabled to display a now 190MHz sinewave.  :)
So it works as expected in SA mode so it's time to dig deeper why it won't in VNA mode as it needs to especially if we were to take it into the field to check an antenna that might not be performing correctly compared to a previously saved sweep.

Attached are the screenshot of the TRC (trace A View) and the live 190 MHz trace B and the TRC file with a txt extension added so to be able to upload it here.

Yet it won't work in VNA mode !  :rant:
I'll be chasing this up again with Siglent on Monday.

Don't be so hasty as we need check this out first.
Yes datasheet says VNA stimulus now = higher BW models but there are also other error in the datasheet in spec for all models.

No hastiness here, just thinking out loud.

Nonetheless, I remember who has indicated in the past the low freq. distinction as a sign that the HW should be different. ;)
Yep, of course and it's very likely the inbuilt bridge was swapped out however if you hunt through the datasheet there are still a # of differences to the 3.2 GHz model including weight = lesser HW.  ;)

But when the # of VNA data points are wrong by an order of magnitude it screams someone is not doing their job !  :horse:
Fresh arrival.
100 KHz is certainly the minimum stimulus frequency that can be set.

Still waiting for official confirmation......

Did you ever hear anything back? Was the HW improved to support this lower frequency operation? Thank you!

Or that you can not set load impedance, but the rest are possible? I have a few Anritsu calibration kits I'd like to use (such as OSLNF50A-8), so have the actual measurements/values.

For those curious about the user defined calibration info, I went ahead and purchased one, and you can enter delay (time or length, all units like mm/m/etc) and C0-C3 for open and short, and load is indeed fixed, you cannot change the delay or impedance. Through you can change the delay.

I'm having a terrible time interfacing with the SVA1032X over USB.  It is quite frustrating as I have some testing I'd really like to automate.  I'm using python and the python-usbtmc package.  What I'm seeing is that not only do I get unreliable communication but I get a lot of duplication.  To be more concrete, here is a simple example:

import usbtmc

# create the instrument
sa = usbtmc.Instrument(idVendor=0xf4ec, idProduct=0x1301)

# reset
sa.write("*RST")

# using try/except because half the time it fails with an exception
for i in range(10):
    try:
        r = sa.ask("*IDN?")
        print(r)
    except:
        print("FAIL")

# can repeat with ":SYST:DATE?", ":SYST:TIME?", ":SYST:LANG?" and not only does it fail often
# but I routinely get the result from a previous command instead of the one I just issued.


As a note, the same code but with a different idVendor and idProduct to point at some Keysight and also Rigol stuff has no problems.  It just zips through giving expected results.  I also tried on a Siglent arbitrary waveform generator and not only was "*RST" not accepted but I had the same unreliable results with "*IDN?", "SYST:DATE?", etc.

Any suggestions?  I'm pretty frustrated that this isn't just rock solid as computer control is just expected on equipment.

Thanks

Instead the NIVISA USB and LAN drivers are normally installed when the webserver is not intended for SCPI commands.

All the firmware versions and drivers plus the EasySpectrum package for USB and LAN instrument management if the webserver doesn't suit your needs.

With Siglent SSA/SVA you get access to SCPI via Telnet on the Ethernet port. Much simpler and no extra dedicated library required.

Please take VNA discussion to the correct threads.  :horse:

Tautech OK :) As requested ;)

Then I'll ask here again ;) Are you able to find out what ECal models the SVA1000X supports with the latest firmware V3.2.2.6.0R7 ?

The second issue that RoV raised concerns the possibility of changing the IF bandwidth in VNA mode. Currently, the bandwidth in VNA mode is fixed at 10kHz (IFBW in the Stimulus menu) and cannot be changed (according to the documentation) - photo in the attachment.

Is it planned to change IF BW in future firmware and is it possible technically (possibility to set a lower value, e.g. 10Hz) ?

Show me the menu....screenshot not a photo please.

Currently there are no ECal kits available from Siglent however when I had a SNA5000A several from other brands were supported.

Study of the SNA5000A manual might reveal what ECal kits are supported.

Siglent currently only offers mechanical calibration kits (not ECal). Although the SNA6000A video ad shows such ECal from Siglent (most likely, ECal from Siglent will appear in the commercial offer) ;)

The SNA5000A supports ECal from Agilent/Keysight (N4433A, 85092C)
https://siglentna.com/operating-tip/sna5000a-supported-ecal-units/

Although watching the SNA5000A reviews on the YT channel "The Signal Path" it seems that they actually support more models than listed in the above-mentioned place.

Only this information applies to SNA5000A, not to SVA1000X. Previously, the ECal option was inactive in SVA1000X, only in the latest firmware it was added - but without information what ECal models are supported.

I add screenshots (ECal and IFBW) in the attachment (ehh I had to look for a flash drive that always has to go somewhere)..

The message : ECal info not found tells us it needs be plugged in and a hunt back through early release notes for SNA5000A finds this:
1. Solved the menu button is not updated when the electronic calibration module is inserted or removed.

Still that does not tell us which ECal models are supported and nothing in the latest SVA1000X does either.
I'll ask if more info is available......

*** SIGLENT FEATURE REQUEST ***

The new SVA1032X firmware upgrade 3.2.2.6.0R7 upgrade works, BUT...
 :-- The field "IF bandwidth" for the VNA is still grayed at 10 kHz and this seriously limits the performance of the instrument.
So, please, if somebody here can contact Siglent, ask them to change this! Even the NanoVNA can configure lower BWs, improving the measurement noise and hence the dynamic range.
Based on the hardware performance in SA mode, the instrument should be able to reach 100 or better 10 Hz BW.

Thank you very much.

How does the FFT on something like a sds1200X-E, compare to an entry level dedicated SA , for sub-200MHz ?
The obvious differences are:
To learn about the basics of FFT in e.g. an SDS1104X-E, you can study the corresponding chapters of my review. The article also contains some examples, including a broadcast overview of the FM radio band:

https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-in-depth-review/msg1371782/#msg1371782 (https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-in-depth-review/msg1371782/#msg1371782)

Of course, this is a bit outdated by now and additional tools and features have been added even to the low end SDS1004X-E series since then. For example, the setup is a bit easier now, because we can choose any FFT length independently, as long as it is not longer than the record length. Consequently, all the extensive tables in the article have become meaningless by now.

Because of this, the basic setup for a contemporary Siglent DSO is better described in the following post:

Hello everyone,

I just upgraded my 1032X firmware to 3.2.2.6, released last Friday. Boot-up time is now over 12 minutes |O

I'm going to have to roll my unit back to a previous version, so I thought I would give everyone a heads up.

New features are listed as:
• Add ECal in VNA mode
• Add three new formats in VNA mode: Unwrap Phase/Real/Imaginary
• Add Z Reflection in VNA mode
• Add PM demodulation in MA mode
• The time of analog demodulation in MA mode is adjustable

Tried the features (except for the ecal, I don't have a spare kidney need for it) and they all seem to work, but the boot time just isn't worth it unless you NEED phase modulation measurement.

I remember posts mentioning problematic system response due to very large log files clogging the file system, caused by some missing configuration causing error logs at each boot. If I remember well, it was due to the default VNA calibration files missing. Those logs could be deleted.
Search here or in the SSA thread.

Sorry my short hand for entering buttons is lacking.  I don't think there are any 2 simultaneous  button presses on this machine.
Assuming the unit powers up.  (if more than an hour I don't think it will)
Press System button.  The soft buttons appear on the screen.
Press the 'Pwr On/Preset' soft button.  A new soft button menu appears.
Select the 'Def' for both the Power On and Preset soft keys.
Press the 'Factory Reset'

Can you Telnet into the machine?

Thank you @bicycleguy, @RoV, I managed to fix it.

The unit was completely locked out of all soft buttons.
The unit would respond to, but not actually execute SCPI commands. The system reset procedure linked wouldn’t actually reset anything, nor would it restart the unit when instructed to.
The web interface was still up though, so I tried to upload 3.2.2.5 through the web interface (it took three tries but it eventually worked). After a longer than usual wait, it successfully downgraded, and booted up in 3.2.2.5.

This allowed me to then perform a factory reset with SCPI commands before upgrading back to 3.2.2.6.

All seems to be working now. 22s boot time.
Phew! Thank you all, I went to bed quite worried last night!

Currently running firmware SVA 3.2.2.5.1R1. Does flashing the newer firmware 3.2.2.60R7 remove the options, or do they stick around after updating to the latest?

Ony issue I can see is that there seems to be no spectrum display in RTSA mode?    That said it might be operator error.  Other modes are working fine.

RTSA is not a SVA option. You see it because you "hacked" it.
Turns out that Siglent enabled the menu option (in "MODE") from some SVA firmware version. When you try to use it you obtain frozen displays. So it seems to work!

Yesterday I was intending to show the spectrum monitor option to someone and I didn't remember that it was among the "Measure" options. So I went to "Mode", found "RTSA", activated it, and I spent half an hour trying to find out whether I had to mess with some trigger to make it work!  |O

My fault of course, I had forgotten about "Spectrum Monitor"

I recently upgraded to Firmware 3.2.2.6.0.R7 on my crossflashed SV1032X.

I have had some odd behavior in VNA mode. I did a factory reset.

After calibrating Open, Short 1 - port and Through I get awful noisy results even when the original load used for calibration is connected.

I get a reading, very unstable of no better than 20db return loss. On the smith chart I can't get a nice neat spot on the centre line - it is all over the place.

I tried two cal kits, one a cheap Nano VNA one and the other a Siglent.  Same results.

I hadn't used the VNA mode for a few months and am unsure whether this is actually related to the firmware upgrade or not.    I have played around with this for hours and am wondering if I have some kind of hardware failure with the directional coupler part of the system, or if the upgrade has not worked correctly with my cross flashed machine.

Right now it is useless for S11 measurements. All appears normal for S21 measurements though.

I wonder if anyone else has experienced this or has some suggestions ?


Thanks

Eloso

Mine works fine after same upgrade.
First of all I would check cables and connectors.
If problem persists, I would check SA operation in stand-alone and tracking mode, to check port functionality.

Thanks for the note. Yes, spent more hours than should be necessary on checking all cabling parts, including reaching for the good stuff that I try to keep on the shelf. Claned and checked everything as per the well knonwn Siglent Video on checking your connectors.

SA, Tracking generator are perfect. VNA is ok on S21. Just S11 which is making me think that there is some hardware issue with the directional coupler in the reverse direction. I would obviously  love for it to be a software issue, even better if its just an oversight but I've been using VNAs for a while now and am quite comfortable with them.  Given the amount of head scratching I'm doing on this problem  I am confident its not just an oversight.

I have a little NanoVNA for portability and certain types of measurements outside the lab and normally its not a patch on the Siglent - but at the moment its outperforming it dramatically. The Siglent doesn't settle down even with Averaging.

Cheers

So, please, if somebody here can contact Siglent, ask them to change this! Even the NanoVNA can configure lower BWs, improving the measurement noise and hence the dynamic range.

The DANL is specified in the data sheet with -156 dBm/Hz. At 10kHz ENBW, this should result in a noise floor of -116 dBm. Is that so bad?

OTOH, the DANL of the NanoVNA is certainly worse, so a narrower RBW is needed to compensate. However, this does not come for free, but it comes at the cost of a slow sweep.

Quote
Based on the hardware performance in SA mode, the instrument should be able to reach 100 or better 10 Hz BW.

I would draw a different conclusion: Hardware performance allows for a low noise floor even with a larger RBW, which in turn allows for a faster sweep.

[ Note that with a DSP-based filter/detector, narrow RBW is easy to realize and not a matter of hardware performance, but only a matter of patience :popcorn:
For instance, 10 Hz RBW would imply a measurement duration in the order of a few hundred ms -- for each frequency point.
There is no way to get around the tradeoff between RBW and measurement duration. So if you want a fast sweep, then narrow RBW is not what you want. ]

DANL is specific to the SA mode. In VNA it is much worse: preamp is missing and the bridge introduces a loss in S11 mode.

OTOH, the DANL of the NanoVNA is certainly worse, so a narrower RBW is needed to compensate. However, this does not come for free, but it comes at the cost of a slow sweep.

Any serious VNA has the BW setting: I have worked with several models from hp (Agilent/Keysight) and Copper Mountain Tech. All of them have it and is useful. It is clear that Siglent had in program to introduce it, otherwise they wouldn't have put the relevant menu option that, sadly, is grayed.

The question is, what's the S21 noise floor when you measure S21 of a "zero-gain DUT" using a stimulus of (say) 0dBm?
(an example of a zero gain DUT is if you terminate port 1 and port 2 with 50R each)

[ And (any) bridge or directional coupler certainly does introduce some additional dynamic range loss for S11 readings, since only a fraction of the signal is coupled to the receiver. ]

Member RoV has no issue with S21 measurements, a through measurement and only makes comment on S11 measurement, a reflection measurement.
I asked for a loaded Mag Loss trace which will show if there is a problem or not.

I asked for a loaded Mag Loss trace which will show if there is a problem or not.

I mentioned S11 because it tends to be more noisy due to the additional loss introduced by the internal bridge. S21 doesn't use the bridge, because the analyzer is a T/R, not a full 2-port, so in S21 mode is equivalent to the SA in tracking mode (however, in VNA mode it misses the BW setting respect to SA mode).
If you measure a load you will find S11=0 with some noise. If you look at it in Log Mag mode, you'll see a noise level around -something (perhaps -50 dB?). Decreasing the BW, this would improve.
This is particularly critical if some device is inserted. For example, when measuring an external antenna impedance, in order to avoid the risk of damaging the VNA due to external signals, I prefer to insert a limiter in series to the port (full limit @5-10 dBm), followed by a 10 dB attenuator . Then I calibrate AFTER those devices. In this way the VNA port is very well protected, but >20 dB attenuation are added to the measurements (the chain limiter+attenuator is passed twice, first by the test signal and then by the reflected one), so traces tend to be very noisy (even during calibration) unless BW is kept small. This procedure worked very well with an old hp 8714ES, but doesn't with the SVA1032X.

Understood however I have never used such practices for S11 antenna measurements of which I have done many.

Your HP might need additional protection and caution in use however SVA is not the same beast and a quick look at the datasheet states this for TG spec.

I don't think the 30 dBm rating applies to port 1. It does, for a brief time and -I believe- with at least 20 dB internal attenuation inserted, for port 2 (SA port).

RTFM/datasheet.
Port 1 is the TG port however in VNA mode the reflection path is protected by the internal bridge just like how Port 2 (RF In) is protected when using an external bridge that provides additional attenuation when in SA mode.

Isolation for Port 1 is from the internal bridge of which we only have the TG reverse spec to work from which the internal bridge is identified shortly after Dave did the teardown early in this thread.
You could look that up and study its datasheet for its reverse voltage and attenuation spec of which Siglent has worked within so to provide the TG spec common to all these SVA/SSA designs.

Common sense would have Siglent null internal bridge attenuation from measurements to some degree so not to have uncalibrated measurements far off the display.

Quote

Port 2 (RF In) has more defined specs as expected and in SA and adjustable attenuation: 0 ~ 50 dB

When having longer antennas, eg. 40+ meter you get to certain times quite impressives levels. Especially when ROV is starting to transmit nearby - or somebody else e.g. in a car.

To that comes - and that is more important for magnitudes - a static charging of the Antenna and coax cable to several hundreds of Volts, which generates enormous HF-Spikes when the max Voltage of the insulation at a certain point in the structure is reached and an arc will occur.
This is not hypothetical - it's a matter of fact. I had a ground plane Antenna, which was not having an inductor to ground on the roof - for 2m only - I measured nearly a 1000v during a rain shower with an electron tube multimeter (ancient) .
I have seen cases where the input and power transistors of transceivers were killed by the peaks produced by static arcs.

but one time grounding does not help if the capacitors (coax line) are re-charged. I would never use port 1 or 2 of the VNA without external protection with an Antenna mounted outside.

Antenna static problems are nothing new and no different to what my pop faced with his end fed 30m SW antenna 75 years ago well before I was even a twinkle in his eye.
When a child his end feed anchor point and lightning arrestor were still fixed to grandmas house where when young he obtained QSL cards from all over the world and had them all pasted into a book.

BBC, Switzerland and Texas are just a few I can remember he had those SW directional transmission QSL cards for using primitive valve radios of his own builds and some of his own design.

and yes I prefer being one time faint-hearted than being dead forever  :)
Means use limiters and attenuators instead of replacing the input attenuator and other integrated circuits. Or the output of the S11 port.

BTW I bought a spare HMC1118 and have fixed it with Scotch tape on the back of my Siglent for all cases. Not knowing when this IC will be not available from a reliable source as Mouser anymore. I heard about guys, which replaced this IC twice within a week or two. 

But my hobby is playing with 65V LDMOS Fets running with almost 50 Amps.

Hi...
I am still missing a spectrum analyzer for home, but I also want to be able to measure the overtagunsfunktion of filters, so I will probably need the combi device from siglent:
https://www.batronix.com/versand/spektrumanalysator/Siglent-SVA1015X-VNA.html (https://www.batronix.com/versand/spektrumanalysator/Siglent-SVA1015X-VNA.html)
Are there any reservations about this device ?
I had skimmed the manual earlier, the VNA section.
If I have interpreted correctly, the start frequency is at 10Mhz ?
That would be high, if one wants to represent e.g. the transmission line of a 10Mhz filter.

Hello,
I have just bought a sva 1015x and i am a newbie to this stuff. Im going to use it for hobby purpuse ( Ham radio) .

I have all the options on trial now, but would really make them Permanent without changing to much in the unit,

Is it possible for someone to guide me how to proceed?  I have tried to search the forum, but havent found what im looking for.

Best regards

Robert

 Since you are already starting with a SVA 1015X all you have to do is generate the keys and enter them.  The process is pretty much goof proof

Here are the instructions (modified from https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg4692437/#msg4692437 (https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg4692437/#msg4692437))

IV) Enable full options on SVA

1) Launch online python tool: https://www.online-python.com/PX3v0J8nbs (https://www.online-python.com/PX3v0J8nbs)
2) Uncomment  #Model = 'SVA1000X' line (remove #)
3) In your SVA navigate to system info and note HOSTID
4) Input HOSTID into python tool
5) Generate license codes and with SVA menu option System -> Load Option install and options: either one at at time (I did this) or choose ALL

So are these models over 5yr's old? Since they've had new scopes lately, are there any plans for updated VNA's ? I wish there were models closer to the sds2000x+ series prices, or 1000x-e prices. Even if they are only 500MHz BW, that's plenty for all kinds of uses. And a lot more people could afford them.

SVA1015X is the cheapest (ready to go) with SA/VNA capability for a little more than SDS2104X Plus cost.

It was my fist VNA before updating to SVA1032X which remains my fav RF instrument.

Development has been towards higher not lower BW with SVA and SSA3000X-R models pushing to 7.5 GHz as is the SHA800A range which then SNA5000A exceeded with first 8.5 GHz capable models that have recently been lifted to 26.5 GHz.

I can't really remember how these work, but how much easier is it too make a 5GHz SA/VA than a oscilloscope ?

I don't get why no big brand has slower, and I would assume cheaper SA/VA's. Just another thing wrong with the universe.

Post by: switchabl on December 14, 2023, 05:49:16 pm
Much easier.* In order to build a faster oscilloscope, you need faster, (much) more expensive ADCs (and RAM and DSP fast enough to handle all the data). With RF instruments, the trade-offs are quite different. A 40 GHz SA doesn't necessarily have a higher real-time bandwidth than a 1.5 GHz one.

Apart from some low-end portable models that manage to repurpose some wireless chipset (usually with some serious limitations), going below 2.5-3 GHz probably isn't going to change your design and your BOM cost in a meaningful way. Those are almost all going to be single-band superheterodyne receivers anyway (with first IF above maximum input frequency) and there are plenty of relatively cheap synthesizer/PLL, mixer, amplifier, switch, attenuator etc ICs available in that frequency range nowadays. If you are going to sell a 1 GHz version of a modern SA that's probably just about market segmentation and it's very likely a software option.

Above that, it's not just more expensive components that increase the price. For one, the architecture (and the frequency planning) tends to get more complicated. You'll start seeing one or more high bands that potentially bypass the first mixer but need additional filter banks (or a YTF) to maintain image rejection. The tuning range on the LOs (and source on the VNA) might be too large to cover with a single VCO, so there will be additional paths with frequency multipliers and more filters. Speaking of filters, at some point discrete (L, C & R) filters stop being viable and distributed filters are needed instead, along with a suitable PCB material (instead of cheap FR4).

* for a basic, lower-end SA; at the high-end, a modern RTSA might basically have a multi-GHz oscilloscope built-in and can also be highly sophisticated on the digital/software side.

Dear all,

Please forgive me for asking this simple question, but having looked through the topic, I am unsure of the answer in my case.

I upgraded my SSA3021X+ to a SVA1032X a couple of years ago with the help of members of this forum and my good friend "weejag". I confess to not having really understood what was happening in terms of the computing side and I simply did what Dave (weejag) told me to.

I have ended up with a good working device with no serial number, but with all options enabled. Firmware is 3.2.2.5.1R1.r7

My question(s):

1) Can I update the firmware to the most recent without losing the options, as I have no serial number?

And, while I am here,
2) I have the issue that I have seen others with, in relation to the odd calibration behaviour. Is there a fix for this yet?

With thanks in anticipation,

Ellis

You can upgrade, nothing bad will happen.
You should however complete your hack and get the serial back. This will disable all options, but you just generate the keys to officially activate them for your device. This will fix the calibration issue

Many thanks Bicurico. That is reassuring.

Please can you direct me to a message pointing me to how to complete the hack? This wasn't available when I did the hack (as I remember) and there is a huge amount to look through to get there!

I will be delighted to get the calibration issue sorted!

You need to undo your hack - I can't remember the name of the file you had to delete or rename to get into full mode. It's the file that contains your serial number. Better ask your friend to help you or read through the whole thread on what was done to your device, how to undo it and then how to properly license all options.

Thanks Bicurico.

I know I'm a bit thick about this, but do you mean undo the hack (to revert to SSA3021X+),  then simply convert it to SVA1032X by inserting licence codes from the online python keygen?  If this is what you mean, will the use of the 'all' option give me the 3.2GHZ bandwidth plus the VNA and all of the options?

Please confirm. I'm really grateful for your advice.

You don't need to convert back to SSA. After the cross flash to SVA you, at some point, renamed or deleted the file containing your serial.
You need to restore this file
All options will be gone, but you just reactivate them with the ALL option.
Sorry for the lack of detail, but I don't own this device and don't remember the steps in detail.

Thanks yet again Bicurico.

During a long facetime call, my friend, Dave (weejag) and I took the bull by the horns and did as you suggested. We un-renamed the two files that we renamed as part of the old cross-flash process and the serial number re-appeared. Most of the options remained as permanent but the couple that had gone were restored by using the 'all' key. The bandwidth also remained at 3.2GHz. I am very pleased to have completed this upgrade!

I am grateful for your support and encouragement.

Best wishes,

Ellis

Finally you can restore the serial number via SCPI - and then apply the options via the generated keys of the python script. That would be all to come from a factory mode SVA to a real SVA.

SCPI :SRLN <serial_num> (starting with SSA...)

Hello everyone,

I recently received a liberated SSA3021X+, now I'm using it to get into the world of RF.

I seem to have stumbled over a bug though: I connected my SDG6000X to the SVA. It is set to 120 MHz sine @ -20 dBm. This works great.
[attach=1]

Then I want to measure harmonics. The automated measurement works great, but only with RBWs >= 30 Hz. If I set it to 10 Hz or lower, the fundamental and all harmonics will be displayed with an amplitude that is above the reference level. If I set the reference level to +30 dBm, the fundamental will be measured at +36 dBm, with harmonics up to 6 dB above that. Changing VBW has no influence.

Now the funny thing is that I tried to reproduce it after playing around with a different bug, and then I got an error message "Invalid RBW" when trying to get below 30 Hz. After a reboot, I could go below 30 Hz again and reproduce the issue.

[attach=2]

The other bug is: While Harmonics measurement is active, changing the detector from "Pos Peak" to anything else either
* freezes the measurement. The yellow star will appear is it seems to look for the fundamental again, but after it's finished, the graph is not updated anymore. Or:
* will also create "measurements" with extremely high fundamental and harmonic amplitudes. The amplitude even increases with every change between "Neg Pos", "Sample" etc., saturating at almost 200 dBm.

[attach=3]

Can anyone reproduce those issues? I'm on firmware 3.2.2.6.0R7.

Does anyone with an SVA1015X have input N-type connectors that become quite hot to the touch after about 30-45 minutes?
Yes, I have that too. But a lot of measurement devices seem to get warm in order to maintain a stable temperature, so I wouldn't worry about it. Just a weird spot to get warm.

These devices have multilayer boards with large ground planes and massive aluminum shields that together act as heat spreaders. So heat is everywhere including part of the board and chassis where connectors are.. Hence warm connectors ...

I have a genuine SVA1032x and I have not noticed any part of it warm up, not even a little.  I've had mine open to tighten the connector screws (for some reason they got loose) and I can tell you that aluminum is heavy.  With that in mind, I have 20w transmitters with much less mass in the heat sync that barely gets noticeably warm, so I ask, what inside a RECEIVER needs to get that hot???  I would be concerned enough to find out what is generating the heat.

I wouldn't.

Both you, Spacehen and  Self Bias discuss this "temperature" without stating any temperature measured by thermometer.

"Measuring" temperature by touching it with a hand is highly subjective and two different people will have wildly different perception what "really warm is".
Not to mention that a room all this is happening in can vary by 10 °C and nobody takes that into account.

To many people pain threshold for touching hot objects is mere 50°C, and some will report 40-45°C as very hot. Some will go into 60°C sauna and say "it is warm but it's OK"...

So before getting all crazy about it, a measurement should be done.  If connectors are at 70°C than something is wrong...

Your screenshots mean nothing as sweeps are not seen as Ref levels and Scale are not applicable to the signals used. Turn the measurement table Off so Sweep and Span settings are visible and just use Markers and their values displayed on the screen.

Press Preset (check is is set to Factory Default) and show us some aweeps with the trace visible.

Then I would like to see the Mode menu if all the SVA options are actually available.
Does the System info display a SN# and model ?

You could also go into the Display menu and change the screenshot format from Inverted to Normal.

I have a genuine SVA1032x and I have not noticed any part of it warm up, not even a little.  I've had mine open to tighten the connector screws (for some reason they got loose) and I can tell you that aluminum is heavy.  With that in mind, I have 20w transmitters with much less mass in the heat sync that barely gets noticeably warm, so I ask, what inside a RECEIVER needs to get that hot???  I would be concerned enough to find out what is generating the heat.

I wouldn't.

Both you, Spacehen and  Self Bias discuss this "temperature" without stating any temperature measured by thermometer.

"Measuring" temperature by touching it with a hand is highly subjective and two different people will have wildly different perception what "really warm is".
Not to mention that a room all this is happening in can vary by 10 °C and nobody takes that into account.

To many people pain threshold for touching hot objects is mere 50°C, and some will report 40-45°C as very hot. Some will go into 60°C sauna and say "it is warm but it's OK"...

So before getting all crazy about it, a measurement should be done.  If connectors are at 70°C than something is wrong...
Agreed. And using a thermocouple or other sensor physically attached to the object is highly recommended as a thermal camera will only be accurate on matte black surfaces.

I'm not sure if that's possible when the "Harmonics" measurement is active, but I'll try once I'm back home. That bug did not occur in normal SA mode, only when the measurement function was active. Regular sweeps work fine, both with RBW <30 Hz and when using other detector settings.

Press Preset (check is is set to Factory Default) and show us some aweeps with the trace visible.

Sure, I'll do that.

I could take a screenshot, but I already checked that: It has a SN# and all options are permanently active.

Both you, Spacehen and  Self Bias discuss this "temperature" without stating any temperature measured by thermometer.

You're right, and to add to it: It never felt that hot to me. Like, it wasn't hard to touch or anything, just more warm than I would expect. Funnily enough the attached connector/adapter seemed warmer than the outside of the N-Connector on the device too, so I would assume the heat comes from the inner pin.
It never felt "wrong" to me though, so I didn't measure it yet.

So, I tried a few things. First up, just to make sure, here is what the SA set to default settings look like:
[attach=1]
Setting it to a span where I don't have to wait days for the sweep to complete with a RBW of 10 Hz:
[attach=2]
All normal. But switching to Harmonics instantly yields the same problem:
[attach=3]
I tried to hide the table as tautech suggested, but I couldn't make it disappear. Instead, I noticed a different effect: The graph is only wrong for the harmonics that are being measured. So, combined with

With Harmonics it seems the sweep is mostly above the current Reference level so wind it up some to see the whole trace. Whether that will bring measurements correct IDK.
TBH I've never played with Harmonics.....a task for today maybe.

That will not help sadly; the measured value is always above the reference level. Even with the reference set to +30 dBm, it will then read +36 to +38.

One corellation I've noticed: 30 Hz is the lowest frequency the SA will still do in "Sweep" mode. It defaults to "FFT", but "Sweep" can be manually selected. At 10 Hz and below, it's aways "FFT". Maybe the Harmonics measurement doesn't play well with FFT?

So you don't get unreasonably high values in Harmonics measurement when setting the RBW < 30 Hz or the detector to anything but Pos Peak?

Can you specify? I'm not sure what else to provide aside from the screenshots in my earlier post, with the RBW set to 10 Hz / the detector set to Neg Peak with the Harmonics measurement producing readings of up to +200 dBm.

So a good test would be to just repeat your measurement from earlier with the 100 MHz Sine, go to Harmonics measurement, then set the RBW to 10 Hz or the Detector to Neg Peak.

[EDIT] And then also switch between Neg Peak and any option other than Pos Peak. With each change, the reading of the fundamental's power should increase.

So just in case my initial post was unclear: Here's my full setup. 120 MHz Sine @ - 20 dBm, Harmonics measurement. One photo is with 30 Hz RBW, The other with 10 Hz. Aside from the sporadically appearing notch, the yellow line gets clamped to the top because the readings are all abnormally high when the RBW is < 30 Hz. The same happens if the detector is set to anything but Pos Peak.

I did a quick check with my liberated SSA. I used my old RF generator with a lot of harmonics @ 100 MHz (-20 dBm) and I can confirm the strange behavior with RBW <30, with 30 and above it works.

I just checked this on my SVA1032x, latest firmware but with a Rigol DG4062 and got the same results.  More interesting is try this with no signal and your will see same thing happen going from 30Hz to 10Z.  With no signal, at 30Hz with no signal, fundamental freq power reads less than -100dBm, then change RBW to 10Hz and the power of the fundamental reads near +10 dBm on the table.

Ok, analyzer behavior is a bit weird, but does it make any sense to measure harmonics with 10 Hz RBW? It becomes quite difficult to center the frequency well enough and requires very high frequency stability of both generator and SA.
I suppose in Siglent they didn't even test the harmonics function at such a low RBW! It's a bug, but not one I would care about...

I tried with mine several times, at several different frequency ranges, and although it would often let me enter whatever RBW I wanted, occasionally it would tell me RBW out of range and stop me when inputting anything under 30Hz.  I think the bug is that it don't always stop you from entering it.

Thanks for confirming @Bad_Driver and @NY2K. If you have the time, could you also check setting the detector to something other than Pos Peak, e.g. "Neg Peak" or "Sample"?

Ok, analyzer behavior is a bit weird, but does it make any sense to measure harmonics with 10 Hz RBW?

Good question. from my limited understanding, it looked like the Harmonics function either does a small sweep around the harmonics or a zero span for each of them. Sadly there's no documentation on it. If it's zero span, then I agree and it's probably not a useful feature in most cases.

Interesting, I had that feeling too. Did you verify that the tracking generator was off? With it turned on, RBW will always be limited to 30 Hz.

All in all it seems like the validity check for the RBW might just not be working all the time. Though I'm still curious about the detector bug.

I'll toss a stupid question out there because I honestly don't understand this thread (but very interested in it for the same reason)...   

From my understanding, the harmonic test simply avoids sweeping all the stuff between the harmonics allowing a narrow RBW setting to cover all the harmonics in a reasonable amount of time instead of sweeping the whole way, but how small of a harmonic are we looking for? 

I get it, with mine in normal SA mode and set to 1Hz, I can see pretty small signals (IIRC down to -165dBm or so), and that's great for looking at a homebrew duplexer, but from a device harmonics perspective, acceptable harmonics are usually -50 to -100dBc, so is it really necessary to see a harmonic that is sitting down at -160dBm?  I wouldn't consider an SVA1032x the go-to tool for repairing something sophisticated enough to need to see a harmonic down in the natural weeds, so whats the point here?  Is 30Hz not enough?

And if its not enough, go to normal SA mode, set it to 1Hz, and sweep each harmonic manually.

Not a stupid question at all. I was just exploring the device and found those two bugs while doing so. Whether the malfunctioning configurations are actually useful is a different and very debatable question. I would assume Siglent's fix being to lock out RBWs < 30 Hz für Harmonics measurement anyway. Not sure what they'll do about the detector, but maybe also just limit it to pos peak.

I got rid of my SVA1032X.

The reason is that Siglent is not completely honest about the phase noise in its specifications. They state a phase noise of -98dBc at 1 GHz. My device just manages that, but the rest of the spectrum is much worse. Look at the attached screenshot.

I made the phase noise visible for 3 frequencies and plotted them on top of each other. (signalgenerator R&S SMB100)
1GHz is yellow line,
500MHz is red line,
200 MHz is blue line.

You notice that at 200 MHz the phase noise at 10kHz is 13dB worse than at the specified 1GHz. I call that misleading. A renowned manufacturer ensures that the specifications are met across the entire work area.

Many people want to use this analyzer on VHF and UHF and may get disappointed.

So I bought an SSA3032X-R which has a different RF architecture. This one does get the phase noise right over a wide frequency range. See screen dump. Same settings, same colors, but a much better performance on the phasenoise.

I have tried to replicate your measurements with my SSA3021X+ upgraded to SVA1032. Unfortunately my generator is probably the weak ring of the chain, being an old Marconi 2019A. However, I get better results.

1GHz is yellow line,
200 and 500MHz are red and blue lines, I wouldn't bet on the order  :palm: 200 and 500 look slightly better than 1 G.

Yes indeed, your phase noise is better.

I am fairly certain that my measurements on the SVA1032X are not unique to my device because I have read some other reports on the internet (and of course EEVBlog) that the phase noise is not that good over the entire spectrum for this series.

Now you have an SSA3021X+ and I'm not sure if it has the same hardware as an SVA1032X.

Bad phase noise is usually caused by the loop filters in the PLL's. It may be that Siglent has already made improvements to the SSA series.

It is very common to use sample detection in noise measurements. I believe this is even 'a must' by convention.
I just forgot about it during the 2nd measurement. Fortunately it doesn't matter much because we are not measuring at 0.1 dB now.

And as far as phase noise is concerned, there are many more reports of this. Just one with a quick search;

Let's consider for a moment the consequences of bad phase noise.

In the 1st screenshot (SSA3032X-R) you see a carrier.
You don't really want to see the skirts at the bottom. The measured carrier is actually clean, but it is the quality of the spectrum analyzer that causes this to appear. It is phase noise from the (several) local oscillators in the analyzer.

Take a look at the 2nd screenshot.
This is an FPL1007 from Rohde&Schwarz. You hardly see skirts here. That's how you want it. (bandwidth here is 10kHz for display convenience)

Now let's introduce a 2nd carrier.

On screenshot 3 (SSA3032X-R) you see the same carrier and to the left of it a 2nd carrier of -80 dBm.

On screenshot 4 (SSA3032X-R) you can see what happens when we bring the -80dBm carrier closer to the -20 dBm carrier. It is barely visible. It disappears in the phase noise of the SSA3032X-R analyzer.

On screenshot 5 (FPL1007 R&S) you can see that with low phase noise of the analyzer the carrier of -80 dBm is still clearly visible.

Of course the FPL1007 is more expensive but don't forget that my SSA3032X-R has the same hardware as the 3075X-R. Then you no longer talk about entry-level models. Especially not if you buy a few expensive options.

While we are comparing numbers, let's put thing in perspective...

Even SSA3075X-R is still half the price of FPL1007... And that is for FPL1007 base price without any options, that are, by the way, even more expensive on R&S. For instance: 40 MHz BW realtime option on R&S cost 4000 € alone! While it is actually free on SSA3075X-R now...

For 4000€ (only for realtime option on R&S) you can buy ALL the options for SSA3075X-R, that includes a set of nearfield EMC probes...

So my comment on this is : " 2-3x times more expensive R&S SA actually has slightly better performance than SSA3075X-R?
Really? Well it effing better have better performance for the price you pay for it..."

The only reason is for display convenience. If I had  the bandwidth of the FPL the same as  with the Siglent, the noise floor would have dropped below the screen. It was a quick choice to solve it this way. There was no ulterior motive behind it.

Perhaps you do not understand the meaning of my previous post, because you mainly respond on using the expensive FPL.

What I am trying to explain is the importance of good phase noise properties of a Spectrum Analyzer. And as far as I'm concerned, that's not entirely clear if you only rely on the specifications that Siglent provides!

I may be treading on thin ice because there are many 'Siglent believers' on this blog.

But there is a bit of psychology involved. If someone buys a nice car after considering everything and thinks he has made the right decision, he will not easily accept it if someone explains to him that it is a bad brand and that he has made the wrong choice.

I'm not here to bash Siglent and I'm not saying it's a bad brand, but attention should be paid to the things they prefer not to mention.

It is still a Chinese company whose name is suspiciously similar to Agilent and they do their best to copy expensive Western items. There are so many examples that show that Siglent is far from having things in order. You notice it in the documentation and you notice it in the errors in the firmware.

Let's get back on topic:

Screendump_1:
First an addition to measuring phase noise:
As stated earlier, you measure this with a sample detector and NOT with a peak detector. Signent also writes this in his service doc.

As a consequence, you may lose the carrier on the spectrum, but that does not matter for the measurement.

Screendump_2:
Siglent stated that the phasenoise is -98dBc@10 kHz and -97dBc@100kHz
What they don't tell you is that the phase noise increases beyond 300kHz to -97dBc and then drops to -114dBc@1MHz. This makes the skirt larger than expected.   (there is hardly a carrier to be seen as stated because of sample detector)

Screendump_3:
 You can see the difference with the FPL of R&S. What matters now is not that the phase noise is lower, but rather that the skirt is narrower.

Signent could make a good improvement there.

So I'm not complaining about the -98dBc, but I am complaining about its width.

Screen dump 4 & 5:
I tell you ones again that if you spend €11,000 on, for example, an SSA3075X-R (without options) you may be disappointed if your phase noise looks like screendump 4 or 5.

At €11,000 they are really not looking for the hobbyist, so they have to make improvement on that.

It is still a Chinese company whose name is suspiciously similar to Agilent and they do their best to copy expensive Western items. There are so many examples that show that Siglent is far from having things in order. You notice it in the documentation and you notice it in the errors in the firmware.

This is OT from the phase noise but I guess this is a MT (multi topic) thread  :)

In the process of downsizing and eliminating several higher end gear, I'm headed toward either an SVA1075X or possibly a -R of the SSA series.  One thing I have not seen on this blog, flog me if wrong, is the SOLT performance of these units.  In general, it looks like the -R may be either a superior design or given more attention, possibly a few better components.

Can you post an image of your SOLT cal with the load performed last, in LOG form.  How stable is it over an hour or two (assuming analyzer has been warmed for an hour)?

Higher end VNAs are fairly rock solid.  The early FieldFox wanders like crazy.  I'm scared sh-less over the four leaf clovers out of the Siglents Smith chart prior to cal.  I am seeing better than -60dB on the bench VNA and the FF.

I would like to think that Siglent's converters and dynamic range are good enough to get down there but have seen NO plots of such.

It's not quite that simple.

X-R models certainly use different HW to most SSA/SVA models but not all.
We can clearly see evidence of this in SSA+, SVA and SSA X-R datasheets.

With some study we can identify 3 HW versions that cover all models from 1.5 - 7.5 GHz.

I'm sure you're right but what I'm really after is visibility to how well it calibrates and how stable that calibration is.  In spite of videos and web reviews, there isn't much at the VNA end and nothing at the cal end.  A few more looks at how well it behaves up to 7+ GHz would also be helpful.

Hey, you could be an industry leader.  Just get Siglent to support you and your US and worldwide counterparts with a virtual try out online.  You select the instrument which is then connected to a matrix of sources, loads, reflectances, etc.  Our internet bandwidths are high enough to support that fairly well today.

Similar has been asked for before as we have used other equipment via the inbuilt webserver of a beta tester in Oregon.
For Siglent to support such online trial of equipment bookings would be necessary where of course other than using equipment as it has previously been connected and specific port settings for remote connections ....something that I wouldn't know where to start.

Many of us resellers have some demo units so ask around if some close by have something you can visit and test.

I would like to think that Siglent's converters and dynamic range are good enough to get down there but have seen NO plots of such.

Maybe I can help you partially with the following measurement;

My SSA3032X-R doesn't go beyond 3.2 GHz (because I didn't enter a secret key) but it might still give you some useful information. I think the SSA3032X-R is equivalent to the SVA1075X on this subject.

I ran a SOL on my SSA3032X-R and used a SOL  (R&S) specified to 4GHz straight onto the N-connector of the VNA. The tracking generator at 0 dBm

Screen dump_1:
From 1 MHz to 3.2 GHz the reflection attenuation is slightly better than -50dB.

Screendump_2:
I tried a narrower span to see if I could get a little deeper into the noise floor. Span 100 MHz @ fc 3 GHz
The reflection attenuation appears a little more towards -55 dB.

It is difficult to place a cursor because the noise floor varies too much. Remarkably, an average of 100x does not change that...?
It seems to me that averaging does not work in VNA mode.

Unfortunately, the problem is that this VNA have a fixed bandwidth setting of 10 kHz in VNA mode. That causes the return signal to disappear into its noise.

It would be nice if Siglent solved that in the near future. It's not clear to me why they don't implement this.

By the way, a reflection attenuation of -50 dB is a very nice value, but that mainly depends on the job you are doing.

Screendump_3:
An overview of my setup.

Screendump_4:
A quick check whether your VNA is sufficiently calibrated by using an open end rigged coax.

Thanks IM3 !  That's exactly what I was looking for.  I'm not asking you to run it again, but have you noticed that it remains stable for some time?

Yes, -50dB is a decent number, especially if it's repeatable and stable.  For small chip and pcb antenna work, the final result is usually well above -30dB and can be a lot worse but acceptable.

My other units are PNA and early FieldFox, both of which may be gone with retirement downsizing.  They are about 20dB (at 10kHz IFBW) lower but the FieldFox drifts a bit, while the PNA is rock solid (should be at 55lbs / 25kg).  The difference must be in the directional couplers.

And of course, this is where Siglent's 38dB to 40dB corrected directivity comes from.

Glad I could help you.

Stability is not a problem. That is more than sufficient, but that is actually no longer a problem nowadays. When I think about what we had to do in the past to achieve 0.1 ppm, that is no problem nowadays.

Downgrading from high-end equipment such as KeySight, R&S, TEK, etc., takes time to get used to.

The choice not to opt for the big brands but for Siglent or Rigol, etc., is always motivated by money!

You really get less.

And that's fine. But you will notice that many things are not as you are used to.

Measuring equipment is never cheap. If you want to pay less, you have to realize that you will also compromise. That's almost a law of nature.

I think that Siglent makes reasonably good stuff for the money, but with Spectrum Analysers (and VNAs) it really comes down to good hardware engineering and there is still room for improvement.

In addition, there are so many errors in the user interface, which is just software.

A very small example that seems meaningless.
For example, with the SSA or SVA (X, plus, X-R) from Siglent you can change the trace brightness but not the overall screen brightness. It seems small but gives a less good look and feel. It's also annoying.

You also often cannot easily take a step back in the screen menu because there is simply no return or back button. So you have to start going through the menu at the very beginning again. Very annoying. But that's what you get included for free.

If I may advise, And you would go for Siglent than I would buy an SSA3032X-R as I did after I got rid of my SVA1032X.
This device has the best hardware of the series and can easily be upgraded for free with all options  to 7.5 GHz and will cost you around €5000.
(kudos for the hard work some did  to realise this )

That is the big advantage of buying Chinese stuff.   :-DD

You've made many good points.  And it does come down to minor annoyances, minor errors and minor omissions.

Fortunately, Siglent seems fairly responsive.  If you could not access a critical or basic function, I'm sure they would fix it quickly (I hope).

You hit on one of my minor annoyances.  The Agilent PNA and all of their 2000, 3000A/T/G series scopes have no screen brightness control.  Fortunately, you do have trace brightness for those at low waveform rates.  The FieldFox has good menu back function and also brightness control, primarily because of the wide environmental variation it is used in.

I see you have an R&S unit and know the differences.  I don't dare compare the PNA at $65,000 (2012) to the SSA or SVA series.  But if the Siglent gets the job done at low cost, at 10lbs vs 110lbs for my PNA and SA (PSA series), then that's good.

On the SA side, the SSA is somewhat better than the old, big ticket analyzers.  It has around 10dB over the PSA on DANL.  Phase noise is about equal and a bit better on some SSA model variants.

I've recently been lurking the blog doing my due diligence in search for a viable SA/ VNA for amateur radio use, and use as a hobbyist. I was about to pull the trigger on a SVA1015X when IM3's post came up. I would like to mention that I do appreciate the level of expertise in this forum.

I had considered the SSA3032X-R, but do I really need a RTSA, probably not. Is it a a really cool function, yes it is! Looking at the data provided by IM3 the 3032X-R is back in the radar.

I'd hate to invest the extra capital just for the RTSA feature if all of the other performance characteristics are relatively similar between the SVA1015X, and the SSA3032X-R.

From the most recent information in the thread, I want to verify by consensus that the SSA3032X-R does indeed have better phase noise characteristics and better HW than the SVA-1015X?

Thank you for the consideration of my question.

Thank you for the consideration of my question.

As always a lot of things depends on budget, so I can't help with that, but I can explain how I came to my choice.

For now there are 2 main RF designs of interest within the Siglent spectrum analyzers. (The 3rd choice is the 5000 series and too expensive)

The better RF design of the 2 can be recognized in the documentation by a DNAL of -165 dBm.
The simpler RF designs have a more worse DNAL value. More like -156 dBm and -161dBm.

I think all beter ones are the SVA1075X, SSA3075X-PLUS, SSA3032X-R, SSA3050X-R, SSA3075X-R.

Now what I had already described in an earlier post is that the simpler RF design of my SVA1032X has led to poor phase noise in a large part of the spectrum. In any case, worse than -98dBc that Siglent specifies at 1GHz.
The better RF design doesn't have that problem and have the same phase noise across the entire spectrum.

To see how physically different the designs are, I advise you to view 2 links.

For the more simple RF design, watch a video from EEVBlog here:

How I made a choice which analyzer to buy:
Of the SVA series, only the SVA1075X is suitable, but then you pay €9200.

Of the SSA X-PLUS series, only the SSA3075X-PLUS is suitable, but then you pay €7875. But it has no VNA function. I thought that could be upgraded, but it would require some tinkering.

The SSA3032X-R is the cheapest of the SSA X-R series and costs €4830, but you can expand it to 7.5 GHz for free, including all options with the key generator that you can download here.

I had an Advantest R3361B for many years and replaced it by the SVA1032X in 2021 - ordered all options. It is faster and has better resolution. The phasenoise could be better but correlates with it´s price-class. The phase-noise shown by user IM3 is strange - as you can compare with mine or that of user RoV. The signal-generator is a HP8657B and most signal-generators have better phasenoise characteristics than the Siglent Analyzers.
But Siglent is improving over the years but you have to pay for better specs.

Nice MAXI that you performed my measurement setup in the same way and that your SSA1032X has good phase noise performance.

There are good and bad examples of phasenoise indeed. that makes it more unclear.

I started checking my phasenoise because someone on EEVBlog reported his bad phasenoise. That's how it started for me.
I did the measurement as I published here.

I  went to the Dutch supplier with this problem and he presented it to Silent Europa. A few months later this was discussed at the head office in China and it was stated that this was hardware related and could not be resolved.
My supplier then took my SSA1032X back and I subsequently bought an SSA3032X-R which Siglent China indicated had no problems.

I can see that my SSA1032X was really bad compared to some others. I have lost confidence in that RF design and have no regrets that I made the switch to the better RF design.

Whether this is exemplary will only become clear if more people perform the same measurement and post it here.

Discovered the following two items I wanted to leave somewhere regarding usage.

1. the SVA now supports saving in SNP, or S parameter format.  It saves as S1P.  This is very handy for bringing the VNA sweep of a network to an external program for massaging.  This is not in Siglent docs nor in firmware revision guide.

With a quality cable attached and calibrated to the end, attached a small antenna eval board for a response plot, with or without markers.  When saved as STA or CAL, neither one could load back the working state and screen appearance.

2. Enter the CSA save format.  This is not in Siglent docs nor firmware revision guide.  CSA saves calibration AND state combined.  When you load a CSA file, you will return to where you left off, with cal in place, entire setup in place including markers, etc. 

Also, if you find something that is not in Siglent docs, look at their manual for their higher end model, the SNA5032A.

If there is a thread dedicated to usage, please move this there.

The Siglent F604MS says it's similar to the Agilent 85033E that I have.

I ran a cal and not only is it similar, it appears to be exactly the same  :-+

Would you do me a favor and post the F604MS kit cal constants, for the male connector.  This would include OPEN, SHORT, LOAD and possibly THRU.  Critical numbers are the delay in ps or length,  C0, C1, C2, C3  AND L0, L1, L2, L3

While this doesn't fix the internal 85033E kit, it raises hope that the F604MS is an easy way to call up the required constants.  May get lucky and find the same for the N type kit (85032x).
