C. OPERATION OF ADAPTIVE PRE-CORRECTOR

4. NON-LINEAR PRE-CORRECTOR CONFIGURATION

 Status: The status field shows the operational status for the non-linear pre-corrector system.

The possible states are:

 Monitoring: indicates that the adaptive mode is disabled and that either the ‗Static‘ or

‗Monitoring‘ mode (refer to 3.4.1 above) is selected.

 Initializing <nn%>: Indicates the progress of the initial data collection by adaptive non-

linear mode.

 Auto applying: Indicates that correction results of the adaptive non-linear process are

being applied to the RF output characteristic

 Not running: Adaptive operation is suspended by the controller system while adaptive

mode is selected.

 Upper shoulder: Read-out of the measured upper shoulder level for the signal applied to the

non-linear sense port. Displays the result of the last completed iteration by adaptive mode.

Displays the instantaneous performance by ‗Static‘ and ‗Monitoring‘ mode.

 Lower shoulder: Read-out of the measured lower shoulder level for the signal applied to the

non-linear sense port. Displays the result of the last completed iteration by adaptive mode.

Displays the instantaneous performance by ‗Static‘ and ‗Monitoring‘ mode.

 Iterations: Displays the number of adaptive non-linear pre-corrector iterations completed since

reset of corrector characteristic or reboot of the unit.

Adaptive Non-Linear Pre-Corrector Mode Selection

The adaptive non-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 adaptive non-

linear pre-corrector.

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

RF output. The pre-corrector algorithm runs continuously.

 Run to target: The instantaneous adaptive non-linear 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.
