uhd_cal_tx_iq_balance - Generate TX IQ Balance Calibration Table
DESCRIPTION
The Universal Software Radio Peripheral Hardware Drivers handle calibration information. This application sets up Transmitter calibration
for a daughterboard installed on the USRP. Because it also uses the receive side of the daughterboard, this application only handles trans-
ceiver daughterboards.

--tx_wave_ampl arg (=0.69999999999999996)
Transmit wave amplitude in counts
--rx_offset arg (=934400)
RX LO offset from the TX LO in Hz
--freq_start arg
Frequency start in Hz (do not specify for default)
--freq_stop arg

--nsamps arg (=10000)
Samples per data capture
This application measures leakage between RX and TX on an XCVR daughterboard to self-calibrate.
