Thanks for the suggestion.  I'll take a look at that thread.

Shariar's video, however, is the one I linked above, where he does exactly what I am doing...

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.

Ah yes, the dots are starting to connect.

I appreciate the patience you and everyone else has shown in helping me to understand what was happening.

Reference Offset and Trace View

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



I hope you find it interesting.

More so amusing.  :)
Yes the bug needs fixing to protect the operator from their own usage errors.  ;)

Thanks for finding these silly UI errors for Siglent to fix.

@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.

Review of the SVA1015X Network Analyzer Option Firmware Update
« Reply #262 on: June 03, 2019, 07:53:39 am »
Siglent is releasing new firmware for the SVA1015X spectrum/vector network analyzer today.
In the following video I review firmware changes to the Network Analyzer Option.  This firmware fixes flaws and adds excellent new capability to the SVA including port extensions, multiple simultaneous plot types, additional calibration types including user cals, on-screen annotations, and a read only FTP server.



You can get a copy of my presentation here if you want to follow along.

I hope you enjoy it.

Chris

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.

Edit: Pro's and cons of Enhanced Response cal for a T/R VNA is covered in here on page 53:

No Chinese whispers about the SVA3000X models yet other than the one spotted at Electronica last year.
Even the beta testers that I chat to haven't seen one yet.
Some months away yet I guess.  :(

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 ;)

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

Some families asked me for this patch. It should enable telnet as before.

Test and report.

BTW, no need for whispers.

This latest FW (which is quite different from previous ones) has the explanations inside:   :popcorn:

SVA1015X
SVA3032X
SVA7075X
   :scared:

And 5 other options besides what is currently used:

RTA, RCV, SVA, NA and MA

Well yeah that's real interesting as we know from recent info on the Chinese site SVA1032X is not too far away and it seems a 3k series is indeed coming too plus a 7k series.  :o

From what I see in the latest FW, I'll bet that "SVA1032X" is a typo. However it would be great if I'm wrong...
