Hi,
It appears that gr.message_sink and gr…msg_queues are for
digital data. but my flowgraph (periodogram) is for analog
samples,
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?
Thanks
You can use vector sink.
ex:
dst = gr.vector_sink_f()
then you can see the data in this vector by:
print dst.data()
Of course you have to run the graph for a while then stop it before
doing the print.
