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
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
