Product Description

Product Description
Overview
The FLI Module acts as the interface between an external RF source and the Model
GS7000 Node.
The RF signal enters the Model GS7000 Node though port F2 in the node housing
lid. An RF cable assembly is provided to route the signal from port F2 to the input
connector on the FLI Module. (Port F1 entry is optional, but requires a shorter RF
cable.) The FLI Module accepts the RF signal through a female F-type push-on
connector on the top cover of the module housing and routes the signal to the OIB
through a signal pin.
The FLI Module is designed to be mounted in the "RCVR 4" position on the OIB in
the node.
An RF test point on the module provides a sample of the RF signal at -20 dB for level
monitoring.
Note: A special "Local Injection" version of the 1x2 Redundant FCM must be
installed in the node to facilitate the operation of the FLI Module.

Technical Specifications

The FLI Module meets the following technical specifications.
Forward Injection Port
Performance
Operational Gain (minimum) dB
Frequency Response
Internal Tilt (±1 dB)
Input Return Loss
Notes:
1
Forward operational gain is for station from forward injection port to node RF
output port with 0 dB pad in OIB, 1x2 Redundant Injection FCM, 1.5 dB
interstage (I/S) pad, 7.5 dB linear I/S EQ, factory select output pad. Includes
OIB losses; ~ 2.25 dB loss through the FLI Module and RF cable, and ~ 15 dB loss
through the FCM.
2
Internal tilt is "Linear" tilt and is primarily due to an on-board fixed equalizer
and a factory configured 7.5 dB linear I/S EQ.
Input Return Loss specified for Forward Injection port.
