C. OPERATION OF ADAPTIVE PRE-CORRECTOR

3. LINEAR PRE-CORRECTOR CONFIGURATION

Adaptive Linear Pre-Corrector Mode Selection

The adaptive linear corrector can operate in four different modes. The required mode is selected by

opening the operational mode ‗drop-down‘ list (II).

The available modes are:

 Idle: The current adaptive pre-corrector characteristic is applied to the RF output. The pre-

corrector algorithm is stopped. Changes in transmitter characteristic will not be tracked by the

pre-corrector.

 Continuous: The instantaneous adaptive pre-corrector characteristic is applied to the RF

output. The pre-corrector algorithm runs continuously.

 Run to target: The instantaneous adaptive pre-corrector characteristic is applied to the RF

output. The pre-corrector algorithm will run until the set threshold value is obtained for the

upper respectively the lower RE spectrum shoulder.

 Auto run: The instantaneous adaptive pre-corrector characteristic is applied to the RF output.

The pre-corrector algorithm will run until the set threshold value is obtained for the upper

respectively the lower RE spectrum shoulder. The adaptive pre-corrector algorithm will be

automatically restarted in case the upper and/or lower shoulder performance subsequently

drops below the set threshold.

Adaptive Linear Pre-Corrector Threshold Settings

The threshold values for the adaptive pre-corrector system‘s ‗Run to target‘ and ‗Auto run’ modes are

accessed and set by expanding the ‗Auto-run and run-to-target threshold settings‘ control (III). Notice

that the respective parameter values must be ‗enabled‘ by ticking the associated enable field in order for

the parameter to have any effect on the pre-corrector algorithm.
