[Discuss-gnuradio] usrp fft scaling

[Jordan J Riggs]

Hi guys,

Can someone explain how the scaling on the USRP2 (or USRP1) FFT window works? At first I assumed that the scale was referenced to 1mW (so that 0dB = 1mW), but after making some measurements with other equipment, this doesn't seem to be the case. Is this DBoard dependent?

Thanks,
Jordan
