Linear Pre-Corrector Mode Selection

The 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 pre-correction is applied to the RF output (the corrector characteristic is

neutral). The amplitude ripple and the group delay performance is measured and displayed

provided that a valid feedback is applied to the RF sense input 2.

 Static: The currently loaded manual 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 linear pre-corrector characteristic is applied and maintained

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