Anritsu  have announced the introduction of their new S412D LMR Master model, a comprehensive handheld test instrument used for the installation, verification and service of P25 trunked radio systems as commonly used by emergency service and utility organisations.

A lightweight, easy-to-use battery-operated instrument, the LMR Master combines the functionality of a cable and antenna analyser, spectrum analyser, interference analyser, and power meter, significantly reducing the number of tools field technicians and engineers must use, thereby saving time and money while ensuring accuracy.

The S412D provides the full suite of measurements offered by Anritsu’s Site Master analysers along with P25 transmitter measurements and P25 coverage mapping. Covering the 25MHz to 1.6GHz frequency range, the S412D can conduct antenna, cable, transmission, and transmitter measurements, as well as interference analysis. The P25 transmitter measurements that can be made include constellation, EVM, symbol deviation error, and bit error rate (BER).

Recognising that BER is the only true measure of coverage due to multipath and local interferers, Anritsu have designed the S412D with a P25 test signal to measure BER. The measurement capability in such a compact handheld instrument significantly simplifies coverage drive testing. Fast and easy coverage mapping can be achieved with the S412D, as the handheld analyser can conduct 8 hours of BER and RSSI tied to GPS location.

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

The Anritsu S412D instrument utilises the design of the Site Master. Compact yet rugged, the S412D is specifically designed for field environments and can easily withstand the day-to-day field applications. The battery can be changed without tools in seconds, when necessary to help extend measurement time in the field. The colour display is viewable in direct sunlight and at wide viewing angles.
