Receive Systems Module (option for ASM)

RSM0000

The Receive Systems Module (RSM) is an option for the Antenna System Monitor (ASM) that allows the monitoring of two network receive signal paths – i.e. a dual diversity, dual Rx antennas, or hot/standby Rx antenna system, and an isolated (third) external off-air Rx path may also be monitored for additional ASM network monitoring functionality. A peak overload RF level detector is also provided for all three signal paths.

The Receive Systems Module (RSM) is an optional module that may be used with the Antenna System Monitor (ASM) to monitor two receive paths – i.e. a dual diversity, dual Rx antennas, or hot/standby Rx antenna system. An isolated external off-air Rx path may also be monitored to facilitate additional ASM network monitoring functionality. Peak RF input levels are independently detected, monitored and alarmed for all RF inputs, allowing high RF signal levels that may be impacting Rx system performance to be detected, measured, reported and alarmed - assisting in fault-finding activities.

The RSM can be easily added to an ASM at any time, providing a network migration path from non-diversity to diversity technologies. When a RSM is connected to the ASM, the ASM will auto-detect its presence, displaying the respective RSM configuration pages via the ASM GUI (Graphical User Interface). Rear LED’s provide a visual indication of the status of the Power, Rx Inputs’ levels and alarms.
