NAME¶

uhd_cal_rx_iq_balance - Generate RX IQ Balance Calibration Table for a UHD Device

DESCRIPTION¶

The Universal Software Radio Peripheral Hardware Drivers handle calibration information. This application sets up Receiver calibration for a daughterboard installed on the USRP. Because it uses the transmit side of the daughterboard as a test signal generator, this application only handles transceiver daughterboards.

Samples per data capture

This application measures leakage between RX and TX on an XCVR daughterboard to self-calibrate.
