It may be that this is not the most suitable thread but... is there anyone who can tell me if for the SVA1032X it is possible to set the SW options in lifetime mode?
The SVA1032X has a considerable cost and before proceeding with its purchase I need to be sure if the various SW options (the cost of which is prohibitive for my possibilities...) can be permanently enabled.
Thanks in advance to those who want to help me.

Thanks a lot for the suggestion!!! Before purchasing I'll investigate a bit regardig this much less expensive option.
Anyway, regarding this possibility that I'll now explore in detail thanks to your suggestion, I have the doubt that the frequency expansion operated in the transition between 2.1 GHz and 3.2 GHz results in an uncalibrated spectrum analyzer in the 2.1 - 3.2 GHz range and this would be a not negligible inconvenience for this type of measuring instruments! (calibration of a Spectrum Analyzer is usually a very expensive service...)
I am seriously interested in purchasing a SVA1032X.
Is there any owner, based on his experience with the instrument, able to briefly present the pros and cons of the spectrum analyzer and the VNA section respectively?Only that it's just a single port VNA therefore measurements are limited to S11 and S21 types as all stimulus comes from Port 1 (TG) yet for antenna (S11) and one directional tests of filters etc (S21)) it's still very useful.
For DUT's that need testing/measuring in both directions they must be flipped to poke them from either end.
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?
The 2nd thing, I'm wondering about is the the cal kit selection. I have the F603FE kit from Siglent and select that from the menu when doing cals, but I noticed that there isn't a CSV file for it in the vnacalkitdata directory even though it's showing up in the menu. Does anyone know if that is an issue or how the CSV is used?
/usr/bin/siglent/usr/vnacalikitdata
Are you saying that saving and loading a CAL file will produce a CSV file? The files in the vnacalkitdata directory seem to be installed from the factory for only certain mechanical cal kits.
I'm referring to the CSV files not the CAL files. The CSV files are located in the directory structure atCode: [Select]/usr/bin/siglent/usr/vnacalikitdata

The strange thing is that the cal kit CSV files in that folder are only for a subset of the calkit options you can pick from the menus. Makes me wonder if I pick the F603FE and the CSV file does not exist, then what is actually happening?
I don't suppose you can tell us if the new beta has fixes for the weird cal issues I mentioned above when selecting 1-port or through calibration, etc.?
A wee look at this beta FW and Cals.
Some screenshots below with what might be the new max points.
Going through the Cal process for which I used 1 Port Cal as this is mostly what I use and for this a F603FE at the end of a cheap 150mm SMA cable on a N-SMA adapter on Port 1.
Captures for Short and Open were done in the Sort and Open cal and went through them again in the 1 Port Cal where Load is also used but at each step each Cal is Applied however you only see the full result after Load is done.
Marker @ 3.2 GHz added FYI.
Full BW sweeps were quite fast previously however with 10k points they're ~4.5s now.

Can someone with a real SVA1032X check if this happens there also?I have one. I always use the 1-port cal and I just tried the Response Through cal. The frequency settings follow into both calibration screens and it also shows CAL at the top after leaving the cal screens.

Might do some examples of how to Save a Cal for recall 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.
Steve, I suspect you are missing a small but very important step.
Work through 1 Port Cal as you have then re-enter the Calibration menu and select Correction = ON.
Screenshots below just taken show first what a Load looks like with Correction not applied and then applied.

This is interesting... By default my Correction is on, so I never touched it. I will have to try switching it OFF before doing the cal and then switching it back ON after to see if that makes a difference. I'll try this out tonight.
Is your Correction defaulting to OFF?
Can you post a picture of your screen? It looks you are missing a cable because I had the same problem but then my Smith diagram screen was al over the place
