Thanks for the wonderful job you did, especially with the cursor and using FRA4PS as input works fine for me.
I have a point to mention.
In the image showing the impedance, the program also shows a phase. However this is the phase that belongs to the Gain.
In the Image below I show the difference phase that belongs to the impedance.

Thanks for spotting this :-+. Corrected version is attached to first post. In the calculations I always used the phase in radians (which was correct), but converted to degrees from the measured phase instead of the phase from the DUT, exactly like you said.
Hans Polak:
Yep, it's working all right.

Great! Hopefully in the next couple of months I will have some more time to add features like calibration and calculation...

I have used FRA4 quite a lot on and of since it was released. So yours is a really nice contribution to the tools for Picoscope,
expanding on the usability !
As for Hans in the Previous post I can't get the included measurement application to work. See attached file.

I think I found a solution for the X64 problem. Updated version in first post.
Hans Polak:
It works like a charm, nice with this extra settling time and overlaying measurements on top of each other, great job.
The only very very small thing is that you have to start measuring twice.
The first time it contacts the Picoscope and after that you have to press measure again, not very important.
