A91750
Automatic Monitoring of RF Channels
The A91750 is designed for monitoring RF Channel lineups in headends and hubs in a CATV-network.
It can scan and supervise up to 200 channels in the
frequency range 46– 860 MHz at very high speed.
(100 ms/channel)
The RF signals can be either analog TV, FM Radio or
Digital Channels (QAM, QPSK, COFDM).
TM
The A91750 is connected to Scientific-Atlanta`s ROSA
Network Management System (NMS) and is
completely user-configurable. It can be programmed to report two levels of alarms per measured carrier
indicating loss of performance or breakdown of the network or hub.
In combination with device backup applications in ROSA NMS and ROSA EM it guarantees channel, card and
chassis redundancy for devices providing digital TV modulation such as the Scientific Atlanta’s xDQA-24 and
RFGW-1.
The unit is available as a 1U 19-inch rack mount unit.

Monitors analog RF (vision), QAM, QPSK, COFDM and FM carriers
Supports multi-standard, multi-system (BG/I/DK/MN/DVB-C/DVB-T)
Generates necessary triggers for automatic redundancy switching of modulators in ROSA
Instant alarm notification results in significant reduction of outage time
Proactive alarm reporting improves the up-time of the network for better customer satisfaction
Signal level measurements report the health status and network performance continuously
Intelligent alarm reporting: groups different alarms into one or more accurate messages giving more
precise information to the operator for more efficient response to the technical staff
The A91750 RF Channel Monitor sends periodic reports allowing the operator to make statistical analysis
of the network performance
