6 uhd_cal_tx_dc_offset - Generate TX DC Offset Calibration Table for a
7 UHD Device
8
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.
