S412E LMR Master Land Mobile Radio Modulation Analyzer

S412E LMR Master Land Mobile Radio Modulation Analyzer

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.

    • Field analysis and mapping of P25 Phase 1, P25 Phase 2 (TDMA), NXDN™, ETSI DMR, MotoTRBO™, ETSI TETRA, dPMR, and US PTC - integrated handheld analysis of mobile or tower radio systems for Public Safety, Government, Commercial, Railway, Intersite Backhaul, and Critical Infrastructure
    • GSM/GPRS/EDGE and LTE Measurement Options
    • Spectrum Analysis and Interference Analysis testing - Industry's best dynamic range, noise floor, and TOI allows analysis and low level signals even in the presence of strong nearby RF sources
    • Vector Network Analysis and Distance Domain testing for cables, antennas, and connectors - allows measurement and recording/documentation of reflected and transmitted signals in Log Mag, VSWR, Phase, Group Delay, Smith Chart, Real and Imaginary Impedance - fast 850 μsec/point sweep speed
    • Distance-To-Fault measurement using Frequency Domain Reflectometry
    • Return Loss measurement with 42 dB directivity - Insertion Loss measurement with >100 dB dynamic range
    • Occupied BW and spectrum analyzer emission mask allows instantaneous compliance testing
    • Low level interference measurements, even in the presence of strong nearby sources
    • Occupied BW and Emission mask compliance testing
    • Narrowband FM analysis w/ Auto Scan function to identify frequency of unknown transmitters, Indoor and Outdoor Coverage Mapping of RSSI and Transmitter SINAD
    • RF Power Measurements of both CW and modulated signals
    • Supports both indoor and outdoor coverage mapping of analog and digital radio systems - no PC required during measurement! Post-processing of measurement data in KML™ and CSV formats
    • Included NBFM Analyzer quickly and accurately measures Carrier Power, Carrier Frequency, Frequency Error, FM Deviation, Modulation Rate, SINAD, THD, Occupied Bandwidth, and decoded CTCSS/DCS/DTMF. NBFM Coverage Mapping measures RSSI Transmitted SINAD and audio SINAD from user radio, and tags the recorded value with both GPS coordinates and altitude.
    • P25 / P25 Phase 2, DMR (MotoTRBO™), TETRA, NXDN™, dPMR, and US PTC Signal Analyzer Measurements (Measurements vary by Analyzer Mode): Received Power, Frequency Error, Modulation Fidelity, Error Vector Magnitude, Symbol Deviation, NAC and BER for 1011 Hz (P25) or 1031 Hz P25 Phase 2 / NXDN / ETSI DMR, and O.153/V.52 pseudorandom test patterns. BER estimation from voice traffic, and BER/MER (message error rate) measurement from control channel traffic. Linear or Traditional Constellation, Histogram, P25 & NXDN Control Channel hex decodes, TDMA power ramp profile in P25 Phase 2 mode, TETRA Summary display for downlink parameters.
    • P25 / P25 Phase 2, DMR (MotoTRBO™), TETRA, NXDN™, dPMR, and US PTC Coverage Measurements: The LMR Master S412E supports digital radio Coverage Mapping with annotation of received power and BER for 1011/1031 Hz test patterns, and O.153/V.52 test patterns, BER estimation from voice traffic, and BER/MER (message error rate) measurement from control channel traffic along with GPS tagging of data (location and time) enables system performance and coverage analysis without requiring transmitters to be taken offline. With the industry's best receiver, the LMR Master can accurately measure BER and Modulation Fidelity down to realistic -110 dBm signal levels. BER and Modulation Fidelity or EVM coverage maps provide confidence that communications will be possible even with local interference or multipath effects. 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.
