WORKING PRINCIPLE
The unit is designed to automatically monitor FM channels by comparing measurements from an internal tuner to
user-defined thresholds and reference settings. In case of failure, alarms are generated and notifications can be sent
by SNMP Traps, mail and/or syslog. The unit communicates with the outside world via the IP network It comes with a
client-server application serving as graphic user interface that makes it possible to remotely configure the unit, view
measurements and event logs as well as view real time measurements and listen to the audio of a service.
Cyclical monitoring on multiple programs for each receiver
Several receivers (from 1 to 8, depending on license) are available and each works independently of the others.
With multiple programs set on a single receiver, cyclical monitoring is done by setting the tuner successively on each
set frequency for acquisition of measurements and by then comparing the channel reference values with the newly
acquired data. Please note that measurements are collected only once per frequency which explains why a very brief
anomaly will not be detected. Each monitoring element is successively tested according to the hierarchical test order.
With this order; lower level tests will not be performed when a higher level error has been detected. This method also
prevents useless alarms from being sent.
