S412E - Land Mobile Radio Modulation Analyzer and
Signal Generator, 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, the LMR Master combines a high performance receiver / spectrum analyzer with the world's most advanced handheld vector network analyzer plus a CW / P25 (Phase 1 & Phase 2) / NXDN™ / ETSI DMR / MotoTRBO™ signal generator with internally adjustable power from 0 dBm to –130 dBm.
The LMR Master S412E is the ideal instrument for Land Mobile Radio (LMR) and Public Safety System technicians and engineers engaged in field testing the RF performance of P25, P25 Phase 2 (TDMA), NXDN™, ETSI DMR, MotoTRBO™, and 700 MHz LTE public safety radio systems in the Part 90 spectrum allocations. In addition the LMR Master offers support for emerging Positive Train Control systems.
The base model LMR Master comes equipped with a Vector Network Analyzer and Spectrum Analyzer, support for analysis and testing of narrowband FM radio systems, and coverage mapping of 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), NXDN™, ETSI DMR Tier 2, MotoTRBO™, and ITC-R PTC is available. When equipped with the optional GPS receiver support for Coverage Mapping (both touchscreen-tagged indoor and GPS-tagged outdoor) of analog and digital LMR systems, analysis of FDD-LTE for FCC-mandated broadband public safety systems, and analysis of WiMAX (Fixed IEEE 802.16d and Mobile IEEE 802.16e) for intersite backhaul systems is also available. The LMR Master may also be equipped with a Spectrogram Recorder, Interference Analyzer, Programmable Channel Scanner, external High-Accuracy RF Power Meter (including inline sensors), Distance Domain for cable analysis, and a Vector Voltmeter.
The high performance 500 kHz to 1600 MHz vector network analyzer can be used to sweep cables and antenna systems. To power tower-mounted amplifiers an internal Bias Tee is optionally available. Frequency Domain Reflectrometry (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 Vector Network Analyzer 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 is built on the same field-proven and time-tested 9th generation hardware platform used by the Site Master(tm) S362E, the industry's go-to standard for reliability, portability, and accuracy in line sweeping and interference analysis.
The S412E's vector network analyzer 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 vector network analyzer measurements (in either frequency or time domain) are quickly displayed and updated with the S412E's fast 850 μs/point sweep speed, and the VNA display is variable from 2 to 4001 data points allowing maximum flexibility for custom setups. For users who prefer a more streamlined interface, the LMR Master's VNA display can be set to emulate a Site Master.
The LMR Master combines a high performance vector network analyzer with a fully functional spectrum analyzer. 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 makes this instrument ideal for identification and location of low level signals which can interfere with LMR systems, even in the presence of strong nearby transmitters.. The spectrum analyzer coverage can be extended to 6 GHz with option 6. The LMR Master S412E comes standard with an industry-leading low phase noise (< -110 dBc/Hz typical @ 10 kHz offset) 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.

P25 / P25 Phase 2 / NXDN™ / ETSI DMR / MotoTRBO™ / ITC-R PTC Talk-Out Coverage Measurements: The LMR Master S412E supports digital radio Coverage Mapping with annotation of received power and BER for 1011/1031 Hz, 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 lowest receiver noise floor, the LMR Master can accurately measure BER and Modulation Fidelity down to realistic -110 dBm signal levels. BER and Modulation Fidelity 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.
For digital LMR standards the LMR Master's Signal Analyzers provide both RF and Demodulation measurements. RF measurements include Main Channel Power, individual Sub Channel Power, Peak-to-Average ratio, Frequency Error, Occupied Bandwidth, Current Active slot power, ON/OFF ratio and average duty cycle. Demodulation measurements include Demod-SQE, EVM of Channel, individual Sub Channel EVMs and Phase Noise. In addition, the LMR Master displays the spectrum of the signal, Adjacent Channel Power Ratio, Power vs. Time, and the constellation of the demodulated signal.
