Monroe Electronics 632 User Manual

Model 632 IF Demodulator Instruction Sheet

Description

The Model 632 IF Demodulator
provides a Baseband video
signal when supplied with an
NTSC standard signal.

It is designed for use with the
Model 628 Encoder Sensor, to
prevent the loss of the scrambled
signal in systems using IF output
only.

For headends that have video
monitors, and require a high
quality, the 632 provides a low
cost means of driving the monitor
from IF signals.

Installation

IF output only – connect the

of the coupler then goes to
the secondary input of the
model 628.
