FFT data in a file

Hello community,

I am trying to capture the fft data of the received signal in readable
format. I am very much new to software-radio and USRP and facing some

Basically I want to plot the captured fft data in the same way uhd_fft
does. What is the best way to do that? I have explored
usrp_spectrum_sense.py so far. But, when I plot the output of it (square
root of m.data), I don’t see it completely matching with the output of
uhd_fft. Is there anything else I should try?

Any help regarding this will be highly appreciated.
