In general, this will need to be calibrated, and is dependent on individual USRP variations, the daughterboard gain, and decimation settings used with the USRP. It is possible when using usrp_fft.py to use the --ref-scale option to set the equivalent dBFS sample amplitude, which will then set 0 dB in the display to that amplitude.
