How to get frequency spectrum with a specific span by receiver with USRP® Hardware in MATLAB

[rollingstone_6490]

Hi everybody,

I am trying to use a B200 SDR to measure EM side channel and I am more interested in measuring signals at the frequency domain. I guess I would need to FFT the signal received by the SDR to get its frequency spectrum. However, I have not been able to figure out how to set the frequency span and how to program the SDR to record signals with that frequency span using Matlab. I think it has something to do with frame length but I am not sure what the correlation is. Does anyone have any suggestions?

Thank you so much

Based on your question it doesn't sound like the software nor hardware you're using is supported by NI.

You might want to reach out to Matlab's technical support team to see if they have any resources on radio frequency applications with their software.

For questions regarding the B200 specifically, I would reach out to Ettus' support team.
