The Antenna System Monitor 380-520 MHz 110-240 AC; DIN Coupler, is utilized for non-intrusive and continuous measurement of Tx Forward and Reflected power between Tx combiner(s) and their associated antenna(s) for up to 80 channels individually. It also provides measurement of associated Rx Channels and other frequencies. Additionally, the ASM offers capabilities for Tx-to-Rx antenna isolation, Rx sub-system passband gain response, and Transmitter isolation tests.The ASM facilitates channel-specific monitoring of forward and reflected transmitted power, Tx to Rx antenna isolation measurement, and Rx RSSI levels for up to 80 channels. It features four separate forward and reflected paired power measurement inputs for monitoring via high-power in-line couplers. The Antenna Line Coupler, with low loss, is inserted after the Tx combiner on the antenna feeder cable. All frequencies, channel bandwidths, and level thresholds are adjustable via software. Alarm reporting outputs are provided via a rear-mounted DB15 connector, suitable for connection to alarm reporting facilities. Visual confirmation of alarm outputs is available through LED indicators on the front panel. Configuration, diagnostics, and communication management are conveniently handled via an onboard webserver GUI.

Features:

• Individual Channel Monitoring: Allows monitoring of Tx forward and reflected power in multi-channel, digital and analog systems.
• Non-intrusive Measurement: Enables measurement of per channel forward power and VSWR without disrupting system operation.
• High Capacity: Capable of monitoring up to 80 channels, providing comprehensive coverage.
• Rx channel RSSI level or test frequency Tx to Rx antenna isolation monitoring.
• Flexible Inputs: Four separate paired FWD and REF inputs accommodate single or combined transmitter inputs.
• Alarm Reporting: Aggregated summary alarms for faults, VSWR, forward power level, and Rx Level (Tx to Rx Antenna Isolation).
• Configuration and Management: Configuration and alarm threshold level setting via RJ45 Ethernet port, with onboard webserver GUI for easy management.
• Easy Installation: Supplied with one Antenna Line Coupler, additional couplers can be ordered separately for expanded functionality.
