NAME

       uhd_cal_tx_dc_offset - Generate TX DC Offset Calibration Table for a UHD Device

DESCRIPTION

       The  Universal  Software Radio Peripheral Hardware Drivers handle calibration information.
       This application reduces TX DC offset within the specified frequency range using  transmit
       leakage  into  the  receive  path.  Remove all external hardware from the RF antenna ports
       before using this application. This can take up to several minutes with default settings.

       NOTE:  This  application  can  only  be  used  with  the  WBX,  SBX,  XCVR2450,  and   RFX
       daughterboards.
