BLE*/* Installation and Operation Manual

Model Description

Function

SFE-*-*

Starline Forward Equalizer

This bandwidth specific (750 or 870 MHz) equalizer
compensates for cable properties in 1 dB increments
from 2 dB through 22 dB. The appropriate value must
be installed. See the product catalog for additional
information.

SRE-*-*

Starline Return Equalizer

This bandwidth specific equalizer compensates for
cable attenuation in 1 dB increments from 0 dB through
12 dB for S-split (2 dB increments for all other splits).
The appropriate value must be installed. See the
product catalog for additional information.

SCS-*

Starline Cable Simulator

This simulator compensates for cable properties. The
appropriate value must be installed. See the product
catalog for additional information.

JXP-*B

Fixed attenuator

This pad attenuates excessive input signal. It is
available in 1 dB increments from 0 dB through 26 dB.
The appropriate value must be installed.

JXP-TH*C

Thermal attenuators

This option compensates for gain changes with
temperature in the return path.

FTEC

Fast Transfer Electronic
Crowbar

This option is used for overvoltage protection and
replaces the existing surge protector.

LL-BLE-HMS-*/* Status monitor module

This module enables monitoring of the unit’s operating
parameters by the LIFELINE status-monitoring system.
This accessory also requires the deep housing cover.

BLE-LID/SM

Deep housing cover

This optional cover is required to contain the LIFELINE
status monitor module.

RCB87

Response Correction Board

This optional board compensates for system roll-off at
870 MHz. The BLE*/* is shipped with a jumper in this
location which you can replace when additional
response correction is required.

JXP-RPC

Return Path Correction board

This optional board provides additional flatness
response correction in the return path for systems that
must meet especially stringent return path flatness
requirements.

ICS-II

Ingress Control Switch

This option enables remote monitoring, isolation, and
reduction of ingress on the return path by providing
signal attenuation of 6 dB or cutoff of 38 dB typical. The
unit is shipped with a jumper in this location.
