4. NON-LINEAR PRE-CORRECTOR CONFIGURATION

Non-Linear Pre-Corrector Mode Selection

The non-linear pre-corrector system can operate in three different modes. The required mode is selected

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

The available modes are:

 Monitoring: No non-linear pre-correction is applied to the RF output (the corrector characteristic is

neutral). The shoulder performance is measured and displayed provided that a valid feedback is

applied to the RF sense input 1.

 Static: The currently loaded manual non-linear pre-corrector characteristic is applied to the RF

output. The manual pre-corrector characteristics must be generated and uploaded by means of the

PC software package IMD Buster McTwo. The curve format used by the manual pre-corrector

system is incompatible with the curves used and generated by the adaptive system.

 Adaptive: The current adaptive non-linear pre-corrector characteristic is applied and maintained

according to the adaptive pre-corrector mode selected (see below for details).

Non-Linear Pre-Corrector Monitor Panel

The non-linear pre-corrector monitor panel provided information about the instantaneous performance

and operation mode.
