Land mobile radio test system

15 November 2017 Test & Measurement

Bird Technologies has launched its Channel Power Monitor that monitors all aspects of land mobile radio (LMR) systems. It comprises a 1 RU central processor and a variety of sensors, which work together to monitor all components of a radio system, including each individual radio, the combiner, the feed lines and antenna. These inexpensive sensors are placed throughout the system, with a 5% accuracy that is traceable to NIST.

The instrument hosts its own webpage for setup and display of all measurement parameters. This enables access to the system from any computer, tablet or phone on the network, limited only by the network’s security. The webpage displays all measurements and allows for alarms to be set for failure conditions, such as high or low power or poor antenna VSWR. The unit includes both software and hard contact alarms and can also be configured to send an email alert to an emergency condition. Also standard is data logging, which takes reliability one step further by enabling users to see degraded performance before it becomes an emergency.

The Channel Power Monitor continuously monitors radio performance, combiner loss and antenna/feedline characteristics to identify and alarm on critical changes. With the data logging function, long-term performance monitoring can be used to identify performance changes before they negatively impact system performance – enabling a preventative maintenance team to address problems before they occur. Solutions are available for the entire range of LMR frequencies from 140 MHz to 960 MHz.
