Anritsu has introduced TETRA analyser and TETRA coverage mapping options to its LMR Master S412E handheld analyser. Equipped with the new options, the analyser can be used by field technicians and engineers for over-the-air and coverage analysis of TETRA networks. For advanced field analysis, the TETRA analyser includes a special TETRA Summary display so users can view key data, such as base and mobile colour codes, mobile network code, location area code, and mobile station maximum transmit power level.

This new capability allows users to quickly, easily and accurately diagnose and troubleshoot system performance of TETRA networks using over-the air analysis without preamplifiers.

In addition to new capabilities for TETRA networks, Anritsu has updated and enhanced the LMR Master Options 721 and 722 to match technical and lexical changes in the ITC-R Positive Train Control (PTC) standard. Among the updates are the alignment of symbol rates to “Half Rate” and “Full Rate,” and support for new “burst/packet” air interfaces in the ITC-R standard, including updated signal generator patterns.

Further extending the capabilities of the LMR Master S412E, Anritsu has added support for the MA2700A InterferenceHunter Handheld Direction Finding System. Equipped with a built-in electronic compass, GPS receiver, and Preamplifier, it can be attached to a wide variety of directional antennas.

The TETRA options expands the measurement capabilities of the LMR Master S412E, which combines all of the tools required to install, maintain, and certify analogue and digital Land Mobile Radio (LMR) and Professional Mobile Radio (PMR) networks in the shop or field. All the analysers come with a 42dB directivity/100dB transmission dynamic range VNA-based cable and antenna analyser, ultra-low noise spectrum analyser, signal generator, internal power meter, and analogue FM analysis and coverage mapping.

Users can extend the analyser investment by adding options, such as interference analyser, external power sensors (inline and terminating), distance-to-fault (DTF), and vector voltmeter. Signal analyser/generator options are available for APCO P25 (Phase 1 FDMA and Phase 2 TDMA), NXDN, MotoTRBO/DMR, and TETRA.

The LMR Master S412E also offers analysis of LTE and WiMAX (IEEE 802.16 fixed and mobile) for mobile broadband networks. When equipped with the optional internal GPS, coverage analysis for all signal analysers is available. All this testing capability is designed into a rugged, portable, handheld, battery-operated touchscreen package.
