Just like mine

Please do as I'm looking at a SSA3021X Plus and I like the idea that it will be able to perform VNA functions after loading "modified" firmware and performing a calibration.

SSA3021X-Plus, which now works as a SVA1032X with options.
I've up/sidegraded mine from a SSA3021X Plus to an SVA1032X Plus too, and from all the other VNA and other test equipment I have, using the same calibration standard, they all line up so I know it's as accurate as my standards are.
They're from a cheap SMA calibration kit, so sure, they're not going to be perfect at 3.2GHz, but for 2.4GHz, which is where I use it most, it's good enough.
Thanks for all the information in this thread
Do you have a recommendation for a cheap but decent quality calibration kit?

Nice.. so what we have been seeing isnt crazy, once i figure out how to stuff factory cals with our own cals then that should get them working like the real SVA models and less wonky

I'm not sure you and others looking at this right.
With a VNA, you calibrate it before you use it. It's not a case of calibrate it once and leave it until next year when it's cal date comes up.
That's why you can get cal kits, because you need them as much as you need probes for a scope
.
Now sure, you can save the calibration and run off that, but you have to assume that nothing has drifted sufficiently to throw out your measurements, and calibration only takes a minute.
Remember, the ambient temperature, humidity and a ton of other factors can change a VNA measurement, and that wouldn't have been accounted for in a saved calibration.

Right.. im talking about full replication of what the SVA1032X does and looks from factory..
This is what our screens should be looking like out of the box
https://www.eevblog.com/forum/testgear/siglent-sva1015x-1-5ghz-spectrum-vector-network-analyzer-(coming)/msg3086871/#msg3086871That takes two parts, one, a user with a known value cal kit, two how to stuff that particular cal file and were to put it so it then behaves as it would from factory
The end goal is full replication of a factory SVA in all its behaviours and screens out of the box + any enhancements
And now that you did it and know what you are doing have confirmed it actually does work for VNA and more than likely is all there
If you can, it would be good if you could go through the entire feature set of the SVA and confirm if it is all working as expected, any bugs, etc
I can hack it but never have done much with SVA before so thats why all the odd ball questions on just what it should be doing
Edit: Further this whole SVA thing going on is just a free bonus to me... i was expecting to hack just a SSA... that changed when i opened it up and people gawked at the connections to be a SVA ;p
No idea what mine would have looked like on a smith chart as I calibrate before use, but I just turned it on and had a look and this is what I got, so I've got no idea if it saved the previous calibration, only thing I can do it so use a 75ohm load and do a restart to see what happens.
There's going to be variations in each build, so using someone elses cal file is likely to be less accurate than buying a cheap kit off banggood.
Currently i've tested it against my N1201SA Vector antenna analyser and the LTDZ "VNA" and the results are basically the same, but that's to be somewhat expected when using the same standard to cal them against, but at least it shows that it's working to at least the same level as the other kit I've got.
I generally don't use smith charts as i've never had a proper VNA before, but at least this gives me the change to learn how to use them
Yeah, thats actually interesting because the two of you got and looks like tau's calibrated one that but noreply and mine look uncalibrated
Well I just tried to calibrate against a 75ohm load, restarted and it kept that calibration, so as I though, the reason why mine was showing up is because I calibrated it from the start, never thought to try using it without doing it.
Good news though is that it's easy to calibrate and takes a minute, so you just need a kit to do it with, and like I said, the cheap ones are mostly ok for the majority of stuff you're going to use it on.
My SSA/SVA looks completely different.

I'm guessing that's without any form of calibration at all?

tv84 brain when a new Siglent device is released
Is there a control to dim the SVA1032x 'LCD display' (not the reticule display - which has a control)??
Trying to make some videos - but the screen is 'too bright' for my setup - would be nice to turn it down a little if possible
Been lurking about YT to find some DIY TEM Cell stuff
Found something interesting ...
And for a beginners guide this was great ...
Ignoring the 'sales pitch' - this is a great guide to get to know your device (if not allready)

You could use VNC Viewer and do a screen capture from that.

Did you have something connected to TG aka Port 1?
