Hi, In my experimentation, the measured power depends on fft_size and dwell_delay in usrp_spectrum_sense.py while measuring noise power, the larger those values results in higher measured power even if it is normalized based on the fft_size like this.
20*math.log10(math.sqrt(bin)/tb.fft_size) - 20*math.log10(tb.fft_size) -10*math.log(tb.power/tb.fft_size/tb.fft_size) I wonder it is normal operation.
