Re: [Discuss-gnuradio] Log raw data from the usrp_spectrum_sense.py

[Marcus Müller]

Hi Yang,

the Power of the FFT is only calculated inside the graphical sink, the
connection between the USRP source and the graphical sink represents a
complex sample stream.

I'm still not quite understanding what you really want the USRP to do,
would you mind explaining that again?

Best regards,
Marcus
