Land Mobile Radio Modulation Analyzer, Signal Generator, Spectrum Analyzer, and Vector Network Analyzer

The LMR Master S412E is Anritsu’s second-generation solution for installing and maintaining public safety systems. Built on Anritsu’s ninth-generation handheld platform, this solution combines a high-performance receiver/spectrum analyzer with the world’s most advanced handheld vector network analyzer (VNA). It also includes a CW/P25 (Phase 1 & Phase 2), DMR (MotoTRBO™), TETRA, NXDN™, and PTC-ITCR plus PTC-ACSES analyzer and signal generator with internally adjustable power from 0 dBm to –130 dBm.

This instrument is ideal for land mobile radio (LMR) and professional mobile radio (PMR) technicians and engineers engaged in field testing the RF performance of NBFM, P25, P25 Phase 2 (TDMA), DMR (MotoTRBO), TETRA, NXDN, dPMR, and FDD & TDD LTE for commercial, public safety, maritime, and critical infrastructure radio systems. It also offers support for USA Class 1 and passenger railway Positive Train Control systems Interoperable Train Control Radio (ITCR) and Advanced Civil Speed Enforcement System (ACSES). For railway operators that use GSM-R systems, the LMR Master can be configured with GSM/GPRS/EDGE measurements.

The base model comes equipped with a VNA and spectrum analyzer, plus support for analysis and testing of narrowband FM radio systems including coverage mapping of RSSI, transmitter SINAD, and transmitter THD. Optional support for digital land mobile radio standards including P25 (TIA-102.CAAA-C), P25 Phase 2 (TIA-102.CCAA), ETSI DMR Tier 2 (MotoTRBO), ETSI TETRA, NXDN, dPMR, and PTC is available. An optional GPS receiver enables support for coverage mapping (touchscreen-tagged when indoor, GPS-tagged outdoor) of analog and digital land mobile radio systems. It also offers options for over-the-air analysis of FDD-LTE for broadband public safety systems and analysis of WiMAX (Fixed IEEE 802.16d and Mobile IEEE 802.16e) for intersite backhaul systems. The instrument may also be equipped with a spectrogram recorder, interference analyzer with support for the Handheld InterferenceHunter™ MA2700A, programmable channel scanner, external high-accuracy RF power meter (including both terminating and inline sensors), distance domain for cable analysis, and a vector voltmeter.

The high-performance 500 kHz to 1600 MHz VNA can be used to sweep cables and antenna systems. To power tower-mounted amplifiers, an internal bias tee is optionally available. Frequency domain reflectometry (FDR) distance-to-fault measurements are used to characterize antenna systems. The distance-to-fault measurements can easily spot poor connections, contamination, damaged cables, and water penetration. Both the VNA and spectrum analyzer can be optionally extended to cover up to 6 GHz. Patented RF interference rejection enables accurate, repeatable measurements in the presence of high-level RF activity.

The LMR Master S412E’s VNA offers excellent 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 multi-couplers, and tower-mounted amplifiers. The measurements (in either frequency or time domain) are quickly displayed and updated with the S412E’s fast 850 μs/point sweep speed. The display is variable from 2 to 4001 data points, allowing maximum flexibility for custom setups. For users who prefer a more streamlined interface, the display can also be set to emulate an Anritsu Site Master.

This solution has an excellent DANL of -152 dBm (RBW = 10 Hz, Atten = 0 dB, f < 2.4 GHz) combined with a third-order intercept of over +16 dBm. This makes this instrument ideal for identification and location of low-level signals that can interfere with land mobile radio systems, even in the presence of strong nearby transmitters. The LMR Master S412E comes standard with an industry-leading low phase noise (< -100 dBc/Hz typical @ 10 kHz offset) that allows precise measurement of NBFM, P25, NXDN, and DMR emission masks.

The high-accuracy power meter option provides true RMS measurements using external sensors, including inline sensors. It is the ideal solution for making accurate measurements of both CW and modulated signals. Channelized power measurements can be made with the internal power meter, and the channel scanner option provides users with a convenient way to scan up to 20 channels.

The LMR Master S412E includes data analysis software, soft carrying case, rechargeable/field-replaceable battery, AC/DC power supply, 12V automobile cigarette lighter adapter and a comprehensive User’s Guide.

PIM Hunting mode is optimized for finding external IM products in conjunction with the MW82119B PIM Master.

Mapping may be done both indoors (using touchscreen tagging) and outdoors (using GPS tagging). Coverage mapping generates files in both tab-delimited CSV and industry-standard KML format which are directly written to USB memory for record-keeping, offline analysis and mapping.
