P25 analyser

Wednesday, 01 April, 2009 | Supplied by: Anritsu Pty Ltd


Anritsu has introduced the S412D LMR Master model, a handheld test instrument used exclusively for the installation, verification and service of P25 trunked radio systems.

A lightweight, battery-operated instrument, it combines the functionality of a cable and antenna analyser, spectrum analyser, interference analyser and power meter, reducing the number of tools field technicians and engineers must use.

The instrument provides the full suite of measurements offered by the company’s Site Master analysers, plus P25 transmitter measurements and P25 coverage mapping. Covering the 25 MHz to 1.6 GHz frequency range, the tester can conduct antenna, cable, transmission and transmitter measurements, as well as interference analysis.

P25 transmitter measurements that can be made include constellation, EVM, symbol deviation error and bit error rate.

Recognising that BER is the only true measure of coverage due to multipath and local interferers, the instrument has been designed with a test signal to measure BER. This capability simplifies coverage drive testing. Fast and easy coverage mapping can be achieved as the analyser can conduct 8 h of BER and RSSI tied to a GPS location.

Master Software Tools provide data management and post-processing tools. The software provides a method to manage, archive, analyse and print measurement reports; customise cable, antenna and signal standards lists; and keep the analyser up to date with the latest instrument firmware. In addition, Master Software Tools can log RSSI or BER measurements and GPS location/time into a PC.
