Is it possible to access Waveform "Frequency" measurement thought the Python SDK

[Hatman]

Good Morning All,

I am a newbie to the forum, and python programming/scripting in general.

I have recently purchased an Analogue Discovery 2, and the unit is set-up and running manually through Waveforms - so far its great!!

A key part of my operation is to measure the  frequency of an incoming clock stream.  I have achieved this by feeding it the scope, and using "Measure Frequency" - I've even printed it out using a script.

I would now like to recreate the "project" in python, and embed it into a larger system.  So the question I have,

"Is it possible to read frequency directly from the AD2 Scope using a call with the SDK"?

If not, I assume I will need to capture a sample stream of data, and then analyse the data to extract frequency.

Kind Regards to all,

Hatman

Hi @Hatman

The WaveForms application Scope measurements are not available in the SDK.
The Spectrum/FFT peak with weighted average should give a more accurate frequency measurement.
For this you could use the newly added FDwfSpectrum# functions.

Many thanks @Attila, most appreciated

I will have a look at that function.

Kind regards
