Looking help how to setup WFs for THD measurement of 315Hz in the range of voltages

[xchg.ca]

I spend quite a bit of time massaging WaveForms in order to get my Analog Discovery measure THD of 315Hz in range of 44mV-1.377V

Simple table in Network Analyzer does not work ( also why cant we load table from external file ? ) For some reason it just sticks to first value in the table, and uses it on every step.

I tried scripting but I can not seems to use step as index of an array of V values

I tried Wavegen, and created a sweep 315Hz from 44mV to 1.377V ! Which is good, but how do I plot it now? Network Analyzer is not using my custom Wavegen function, but using only its own V(F) function.

Please help

Hi @xchg.ca

I've added support for this in the latest version:

Beautiful ! You are the MAN ! :D

@attila super happy that these features are added !

But 3.19.19 is not detecting my Analog Discovery ( V1 )

Reinstalled 3.18.1 and it is working.

OS Name    Microsoft Windows 10 Pro
Version    10.0.19044 Build 19044

Hi @xchg.ca

It many be related to the newer driver installation method.
Did you get any error/warning during installation?

The FTDI driver should also be installed automatically from Windows Update or you can install it from:

AFTER

I installed 3.19.19 worked !

But when I installed FTDI drv before installing 3.19.19 it did not work.

Thank you for your help

Sorry @attila I still have issues

Here is the screenshot when running Scope it constantly pops this dialog, Scope start and stops. I have to stop Scoping to shut it up.

Wavegen works fine for example< Network seems to be working fine as well

Also I have run SpeedTest, and I got the same popup during the SpeedTest once

Hi @xchg.ca

Please uncheck the "acquire noise".
Sorry for this issue, but the application is in the middle of implementing few new things and this seems to be broken.
