Description

The RFI Antenna System Monitor (ASM) provides channel-specific forward and reflected transmitted power monitoring, a Tx to Rx antenna isolation measurement and Rx RSSI levels for up to 80 channels. Four separate forward and reflected paired power measurement inputs facilitate monitoring via high power in-line couplers. The low loss Antenna Line Coupler is inserted after the Tx combiner on the antenna feeder cable. All frequencies, channel bandwidths and level thresholds are software definable. A DB15 rear-mounted connector provides alarm reporting outputs that can be hardwired into most alarm reporting facilities. The LEDs on the front panel of the APM allow visual confirmation of the hardwired alarm outputs. Configuration, diagnostics and communication management is facilitated through the use of an on-board web server GUI.

Features:
. Individual channel monitoring of Tx forward and reflected power in multi-channel, digital and analog systems.
. Non-intrusive measurement of per channel forward power and VSWR.
. Capable of monitoring up to 80 channels.
. Rx channel RSSI level or test frequency Tx to Rx antenna isolation monitoring.
. 4 separate paired FWD and REF inputs to accommodate single or combined transmitter inputs.
. Aggregated summary fault/ VSWR / FWD power level / Rx Level (Tx to Rx Antenna Isolation) alarms.
. Configuration and alarm threshold level setting via RJ45 Ethernet port.
. ASM supplied with one Antenna Line Coupler, additional couplers ordered separately.
