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.
