Spectrum Analyzer in Waveforms SDK

[emartine]

Hello! I am trying to get access to spectrum analyzer measurements using the Waveforms SDK. Anyone knows / can give a hint on how to do this? I didnt find anything in the documentation regarding spectrum analyzer functions.. ☹️

Thanks!

Hi @emartine

The measurements in the WaveForms application are accessible from the Script tool.

The newer WF beta adds FFT functions to SDK but not the measurements.
- SDK: functions FDwfSpectrumWindow, FDwfSpectrumFFT; examples AnalogIn_Spectrum.py AnalogIn_FFT.py

Thanks for your reply @attila.

Is there a way I can start the device and get a measurement using SPI?

Hi @emartine

The measurements are performed in the WF app and not in the device.

If you want to send these over SPI you can do it like this using the Script and Protocol tools.
Here I used Logic Analyze to verify the SPI transmission.
