Radio Frequency Systems to Debut New RF Monitor

(click thumbnail)The new MS Series RF 2 from Radio Frequency SystemsRadio Frequency Systems is launching the second generation of its RF monitoring system at the NAB Show.

Typically used for monitoring the RF status of broadcast antenna and combiner systems, the MS Series 2 supports simple network management protocol (SNMP) communications, which enables integration with a high-level network management system (NMS).

The revamped monitoring system sports a completely new operating platform, making it easier to configure.

“Using the eight-inch color touchscreen, operators can easily program alarm thresholds and calibrate full-scale deflection when the transmitter is operating at full power. This simplifies monitoring of forward and reflected transmitter power,” said Mark Betts, RFS broadcast projects and systems sales engineer. “An active, real-time MIMIC display shows the U-Link — or motorized — switch and multichannel combiner configurations. It can also be used to indicate whether full- or half-power is being delivered to the antenna.”

At the local level, alarms can be reset directly from the touchscreen display. SNMP traps can be configured to alert the network operations center (NOC) that an alarm condition is present. The status of the monitor system can also be viewed remotely using a Web browser. Alarms can be reset via the Web interface, and configuration of important parameters such as VSWR alarms is possible.

Highly accurate detectors measure the RF power of multiple transmitters — up to 14 in the monitor’s standard configuration, according to Betts.
