These utilities perform calibration sweeps using -transmit leakage into the receive path (special equipment is not required). -The results from a calibration are written to a CSV file in the user's home -directory. UHD software will automatically apply corrections at runtime when -the user re-tunes the daughterboard LO. Calibration results are specific to an -individual RF board. - -**Note:** -When a calibration table is present, -and the user wishes to override the calibration settings through the API: -the user should re-apply the desired setting every time the LO is re-tuned. - -UHD software comes with the following calibration utilities: - - * **uhd_cal_rx_iq_balance:** - mimimizes RX IQ imbalance vs. LO frequency - * **uhd_cal_tx_dc_offset:** - mimimizes TX DC offset vs. LO frequency - * **uhd_cal_tx_iq_balance:** - mimimizes TX IQ imbalance vs. LO frequency - -The following RF frontends are supported by the self-calibration utilities: - - * RFX Series transceiver boards - * WBX Series transceiver boards - * SBX Series transceiver boards - * CBX Series transceiver boards - -******************************************** -Calibration Utilities -******************************************** -UHD software installs the calibration utilities into **<install-path>/bin**. -**Disconnect** any external hardware from the RF antenna ports, -and run the following from the command line. -Each utility will take several minutes to complete. -:: - - uhd_cal_rx_iq_balance --verbose --args=<optional device args> - uhd_cal_tx_iq_balance --verbose --args=<optional device args> - uhd_cal_tx_dc_offset --verbose --args=<optional device args> - -See the output given by --help for more advanced options, such as: -manually choosing the frequency range and step size for the sweeps. - -**Note:** -Your daughterboard needs a serial number to run a calibration utility.
