TRANSMITTER/RECEIVER/OBSERVATION RECEIVER SIGNAL CHAIN CALIBRATIONS
Figure 149. Tracking Tx/Rx Calibration Configuration Through TES
When an automated TDD configuration is used based on the TDD frame length, some of the tracking calibrations are automatically disabled
in TES if the Rx/Tx frame length is less than 1 ms. If the receiver frame is less than 1 ms, RX_HD2, and RX_QEC_WBPOLY are disabled.
If the transmitter frame length is less than 1 ms, TX_DPD_CLGC, TX_QEC, and TX_LO_LEAKAGE are disabled. This ensures the correct
TDD operations with the user-provided TDD timing parameters. Therefore, it is recommended to follow the same requirement when configuring
tracking calibrations in own software. To violate this rule for better possible performance, carefully evaluate the tracking configurations with a
long TDD stability test.
