Anritsu S412E Land Mobile Radio Analyser

Click2Contact

The Anritsu S412E LMR Master is Anritsu’s second-generation solution for installing and maintaining public safety systems. The solution combines a high-performance spectrum analyser with a vector network analyser (VNA) and signal generator with internally adjustable power. The instrument supports analysis and coverage mapping for P25, P25 Phase 2, DMR (MotoTRBO), TETRA, NXDN, NBFM, FDD and TDD LTE.

The instrument is suitable for land mobile radio (LMR) and professional mobile radio (PMR) technicians and engineers engaged in field testing the RF performance of commercial, public safety, maritime and critical infrastructure radio systems. For railway operators that use GSM-R systems, the LMR Master can be configured with GSM/GPRS/EDGE measurements.

The built-in high-performance VNA can be used to sweep cables and antenna systems. To power tower-mounted amplifiers, an internal bias tee is optionally available. Distance-to-fault measurements are used to characterise antenna systems and can easily spot poor connections, contamination, damaged cables and water penetration. The built-in receiver combined with the signal generator can be used to conduct receiver sensitivity tests.

The built-in GPS receiver enables users to conduct drive tests and log key signal quality parameters. For analog FM systems, RSSI, THD and transmitter SINAD can be mapped. For digital LMR systems, BER, modulation fidelity (or error vector magnitude) and RSSI can be mapped. All data points are tagged with a GPS location and time and can be saved in an industry-standard KML file format for viewing with geo-mapping software such as Google Earth.
