Anritsu S412E Land Mobile Radio Analyser

Click2Contact

The Anritsu LMR Master S412E 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 LMR Master S412E’s VNA offers good transmission dynamic range performance (>100 dB) that can be used to view and adjust the RF performance of critical RF devices including filters, duplexers, transmitter combiners, receiver multicouplers and tower-mounted amplifiers. The DANL of -152 dBm combined with a third-order intercept of over +16 dBm makes the instrument suitable for identification and location of low-level signals that can interfere with land mobile radio systems, even in the presence of strong nearby transmitters.
