Wonder when they will take another step up and make a full 2 port machine.

Check the Cn datasheet.  ;)
I listed some of the SVA1032X improvements a few posts back.

I understand that BUT I stand by my bet.

Hopefully the 3032 is a 1032 disguised but it won't be named 1032...

Triple checked!

There are several references in various files inside (add-on files):

at least: 1010, 1012, 1015 and 1032

(see for yourself in the attached files)

BUT the app only has those that I listed previously. And at this moment in the countdown, I go with what the app says.

PS: included the shadow file. Didn't check if it's used.

<guess>
Now that the 1032 appeared in as part of the 10XX series my suspicion is that 10XX is T/R and 30XX series is 2 port.

I reckon they decided that after it went into the firmware.
</guess>

Aha, looking at the picture, it would appear not :)

Looking here: http://www.siglent.com/prodcut-db.aspx?id=1929&tid=18&T=2
There is the same (small) picture with a label of SVA1032X under it. Now my guess looks OK again. :)

New firmware for SVA1015X.

Version V2.2.1.2.2
https://siglentna.com/download/14779/
https://www.siglenteu.com/download/8246/
https://int.siglent.com/u_file/download/19_08_29/b93ec6c209.zip
37MB

Release notes
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
 Fixed Date & Time set bug

Of serious improvement is the reduction of the minimum frequency 10 MHz to 100 KHz in VNA mode. This is a really massive improvement as are some other additions that we've examined in detail over the last couple of weeks.
Thanks Siglent for listening, understanding and implementing.

Responding to some families' requests, here is a .ADS to open a SVA1015X telnet session at port 10101.

Untested. Please report if It works.

EDIT1: This will only work in equipments with PRODUCT_ID = 11402.
 
So, it's only for SVA1015X with current FW.  It won't work on SVA1032X (Product ID 11403).

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:
  • averaging for VNA calibrations, not having it is currently a limit on dynamic range especially at lower frequencies and when calibrating through attenuators
  • log frequency sweep for VNA mode, this is especially useful when sweeping over a decade or more of frequency range
  • additional user definitions for cal kits including actual load resistance
  • Cartesian real and imaginary impedance vs. frequency
  • VNA default file save mode to save all data, not just displayed data

Ok, i joined up just to ask this.  Can anyone confirm that the VNA now goes down to 10khz with the latest .2 firmware? 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.

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.

Interesting.

I received my brand new unit yesterday. I updated to this latest firmware and there is a telnet service listening on good old port 23, root password the well known one.  :popcorn:
