Hi Michael,
since a while we have the problem that the table tab in VNA Tools stops updating after a while when loading another measurement file. In the Graph Tab everything is fine, I can switch between different measurements and the graph is changing. When I go to the table tab, it is not changing anymore, even when I change the Numeric Format, it will change the number of digits but not the data shown. When changing the "conv" or "Format" field it doesn't change at all. Changing between different tabs does not help either, the only thing which helps is restarting the software. I have observed this behaviour for a while, and also before installing the newest software version, but it still seems to be getting worse and worse.

Did anyone else observe the same problem?

Below I added the Information which is listed when starting VNA Tools Software. Is there maybe anything we should update?

Hi Cecile,

I'm not aware of that problem. It would be very helpful for me if you could describe step by step what you do one your side that the tabular tab page of the Data Explorer stops to update.

Try to start from 01_Basic_Example_N(f-m).

Then I could try to reproduce it on my side.

Regards
Michael

Hi Michael,
the problem occurs when:
I click on the   Load(f)_11200_Load(m)_245_01.sdatb.  and  open the table tab, change the conv to Impedance.
than I change to next file (this still works), but than when I want to close the folder I get an error message. As seen in the screen shot. When I click on "Weiter" the table does not change its values afterwards.

The error message is as bellow:

Hi,

I was able to reproduce the behavior and to fix this bug. Thanks for reporting.

This fix will be part of the upcoming VNA Tools version 2.8.2 which will be released around spring 2024.

Regards
Michael
