This is not true (see: usrp_spectrum_sense.py).
complex baseband samples from usrp --> stream to vector
(vectors of fft_size) --> FFT --> complex to mag squared --> (sink or
block to be determined)
Is their no choice other than file sink?
You can use vector sink.
dst = gr.vector_sink_f()
then you can see the data in this vector by:
Of course you have to run the graph for a while then stop it before
doing the print.
