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?
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...
(I'm looking forward to @tautech's save/load examples
