►While programming the device, ensure that all Tx, Rx channels are running off same LO. It is
recommended to turn off the PA during the course of programming to avoid any damage from high
amplitude data transmitted during intial calibration(For TxQEC etc.).

GUI setup
►Program the chip with DPD use case. (For ex. UC50 NLS)
►Make sure Tx-ORx mapping is correct and ORx LO is configured as TX LO in GUI.
►From Transmit tab send signal and check in ORX tab whether signal is reaching ORX with sufficient
levels (-20 to -25 dBm).
►Uncheck ORx Enable in the GUI so that it is not in user mode anymore, and it is available for DPD
tracking calibration.
