uhd_cal_tx_dc_offset(1)		 User Commands	       uhd_cal_tx_dc_offset(1)

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	 cali-
       bration	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 set-
       tings.

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