NAME

6       uhd_cal_rx_iq_balance  - Generate RX IQ Balance Calibration Table for a
7       UHD Device
8

DESCRIPTION

10       The Universal Software Radio Peripheral Hardware Drivers  handle  cali‐
11       bration  information.  This  application reduces RX IQ imbalance within
12       the specified frequency range using transmit leakage into  the  receive
13       path.  Remove  all  external  hardware from the RF antenna ports before
14       using this application. This  can  take  up  to  several  minutes  with
15       default settings.
16
17       NOTE:  This  application  can only be used with the WBX, SBX, XCVR2450,
18       and RFX daughterboards.
