Thanks, I tried to find the example, however I couldn't in the
gnuradio directories. Could you let me know where I can find the
sample code?
Thanks,

Hi,
I am looking for a way to measure noise power through usrp1. I tried
to test with usrp_spectrum_sense.py, however I am not sure the power
values measured is correct, because it is not same values shown as the
graph from usrp_fft.py. I wonder if someone helps me out for this.
Thanks,
Kyungtae

Try building a little app using GRC using gr_complex_to_mag_squared(),
then run it through an
averager.
Or the
gr_probe_avg_mag_sqrd_c()
Block. Pretty straightforward. Should be quite accurate.
gr-radio-astronomy/src/python/usrp_ra_receiver.py computes total
power, using a long-term averager.
