Trigger re-arming

Hi Valerio, 

Were you able to get them working independently - 'external trigger capture' and 'averaging multiple time domain measurements'? 

Thanks, 

Karthik 

Hello Karthik, 

Thank you for your answer. Yes, I was able to make them work independently and both seem to work properly. However, I cannot check the case for trigger rearming (the field remains dark), which I immagine is necessary for multiple acquisition. 

Best,

Valerio

Hi Valerio, 

Understood. I will check and get back. 

A few questions in the meantime - how many averages do you want to do? If it is not a lot and you are only planning to do one time, you can record the files as detailed here (https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1032355/tsw1400evm-hsdcpro-continuous-data-capture-to-data-file) average and then reload the averaged file to view the averaged data and resulting FFT. 

Thanks,

Hi Karthik,

Thank you for your answer. Unfortunately the S/N ratio in my signal can be quite high sometimes but already did how you suggested in some cases. However, I had to perform the spectral analysis in Octave, since I did not succeed to select only a part of the temporal signal in HSCDpro, that is what I need to do. I tried to use the analysys-window cursors in the time domain but it seems to have no effect on the FFT. Is there a way to do so on HSDCpro?

Hi Valerio, 

I suppose what you are asking for is a dynamic short-time Fourier Transform.

Unfortunately, that is not supported in HSDC Pro. You will have to rely on post-processing in Matlab, Octave, or Python. 

Thanks,
