14.1 DESCRIPTION
The RFL 9780 Limiter/Slicer Module (Fig. 14-1) contains two basic functions: a carrier envelope
detector and filter, and a frequency discriminator. The envelope signal is sent to the Logic Module to be
used in noise and loss of signal detection. The frequency discriminator outputs (Guard and Trip) control
LED indicators, and sends signals to the Logic Module (Section 6) for processing. The six basic types
of RFL 9780 Limiter/Slicer modules are shown in the table below.
Assembly Number Bandwidth Line Frequency
106430-1 200Hz
106430-2 500Hz 60Hz
106430-3 1000Hz
106430-11 200Hz
106430-12 500Hz 50Hz
