You can look at usrp_spectrum_sense script. This sweeps a specified frequen=
cy range, does an FFT, and outputs one line for every bin where the magnitu=
de exceeds a specified limit.
You could modify it to just write the samples to a file/pipe like uhd_rx_cf=
ile.

Next, I want to write a program/use an existing program/script which unifor=

Apologies if this exact question is answered before!
Thanks,
