IF Processor Module
The IF Processing module provides frequency response, group delay, and linearity equal
ization for the transmission system. This module also monitors and controls the level of
output power generated by the power amplifier.
I/P - red LED indicates an input fault
P/A - red LED indicates a PA fault (peak to ave)
ALC - red LED indicates an ALC fault
MUTE - red LED indicates loss of video
or IF when in ALC Mode.
Frequency Response Equalization -
ALC -sets reference level of the ALC circuit.
MAG/CUT-IN-MAG potentiometer to set linear
equalization of system. CUT-IN sets reference power
level above when the linearity equalization is active.
OUT/IN - Toggle switch that changes linearity
equalization out or in
MAN/ALC -Toggle switch that changes linearity
equalization into ALC or manual
IF SAMPLE - SMA connector
36
MAN -adjusts gain when ALC is disabled.
