These utilities perform calibration sweeps using transmit leakage into the receive path
(special equipment is not required).
The results from a calibration are written to a csv file in the user's home directory.

+UHD will automatically apply corrections at runtime when the user re-tunes the daughterboard LO.
Calibration results are specific to an individual RF board.
