For the optional initial calibrations, the TES enables or disables these, as shown in
configurable transmitter initial calibrations are LO Leakage (TX_LO_LEAKAGE), Loop Path Delay (TX_LB_PD), QEC (TX_QEC), and Duty
Cycle Correction (external LO only) (TX_DDC). When TX_LO_LEAKAGE or TX_QEC is enabled, TX_LB_PD must be enabled too. When
"transmitter Direct FM/FSK" mode is selected in DMR or AnalogFM profiles, TX_LO_LEAKAGE, TX_QEC, and TX_LB_PD calibrations are not
used. These options are disabled in TES. TX_DDC is only applicable when external LO is used for the transmitter. The configurable receiver
initial calibrations are QEC frequency independent (RX_QEC_FIC), RFDC (RX_RF_DC_OFFSET), and Duty Cycle Correction (external LO
only) (RX_DDC). Similarly, RX_DDC is only applicable when external LO is used for receiver.
The initial calibrations are performed on clicking Program in TES. It takes some time to complete all the calibrations . When it is successful, the
TES shows "Programmed". If not, it shows "Programming Failed". When "Programming Failed" happens, first check if all the external system
requirements are satisfied. For example, no Rx input should present. If it is not the root cause, as the next step, enable/disable the optional
