BLE100 Installation and Operation Manual
Model Description
Function
SFE-100-*
Starline Forward Equalizer
This 1 GHz equalizer compensates for cable properties
in 1 dB increments from 0 dB through 22 dB. The
appropriate value must be installed.
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.
SCS-*
Starline Cable Simulator
This simulator compensates for cable properties. The
appropriate value must be installed.
JXP-*B
Fixed attenuator
This pad attenuates excessive input signal and can be
used to adjust amplifier gain. 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 accessory is used for overvoltage protection.
BLE-LID/SM
Deep housing cover
This optional cover is required to contain the LIFELINE
status monitor module which is available from AM
Networks.
BLE-RCB100
Response Correction Board
This optional board compensates for system roll-off at
1 GHz. The BLE100 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. The
LIFELINE status monitoring module (available from AM
Networks) must be installed to control the ICS.
