NAME

6       uhd_cal_tx_dc_offset  -  Generate  TX DC Offset 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 TX DC offset within the
12       specified frequency range using transmit leakage into the receive path.
13       Remove  all  external  hardware  from the RF antenna ports before using
14       this application. This can take up to several minutes with default set‐
15       tings.
16
17       NOTE:  This  application  can only be used with the WBX, SBX, XCVR2450,
18       and RFX daughterboards.
