S412E - Land Mobile Radio Modulation Analyzer and
Signal Generator, Vector Network Analyzer,
Spectrum Analyzer
The S412E is Anritsu's second generation solution for installing and maintaining public safety systems. Built on Anritsu's ninth generation handheld platform, the S412E combines a high performance receiver / spectrum analyzer with the world's most advanced handheld vector network analyzer plus a CW / P25 / NXDN / DMR signal generator with internally adjustable power from 0 dBm to –120 dBm.
The LMR Master S412E is the ideal instrument for Land Mobile Radio (LMR) and Public Safety System technicians and engineers testing the RF performance of P25, NXDN, DMR and LTE public safety radio systems in the Part 90 spectrum allocations. In addition the S412E offers support for emerging Positive Train Control systems.
The base model S412E comes equipped with a Vector Network Analyzer and Spectrum Analyzer, support for analysis and testing of narrowband FM radio systems, and coverage mapping of both RSSI and transmitter SINAD. Optional support for digital land mobile radio standards including P25, NXDN, and ETSI DMR Tier 2 is available. When equipped with the optional GPS receiver support for Coverage Mapping (both floorplan-tagged indoor and GPS-tagged outdoor) of digital LMR systems, analysis of TD-LTE for FCC-mandated broadband public safety systems, and analysis of WiMAX (Fixed and Mobile) for intersite backhaul systems is also available. The S412E 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) based S-parameter and VSWR measurements are used to characterize antenna systems. The Distance Domain (DTF) 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 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.
The S412E 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 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 provides true RMS measurements from 50 MHz to 6 GHz 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 S412E LMR Master 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.

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 and Transmitter SINAD and tags the recorded value with both GPS coordinates and altitude.
P25/NXDN/DMR/PTC Signal Analyzer Measurements: Received Power, Frequency Error, Modulation Fidelity, Error Vector Magnitude, Symbol Deviation, NAC and BER for 1011 Hz (P25) or 1031 Hz (NXDN/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 and control channel hex decodes.
P25/NXDN/DMR/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 S412E 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 (based on a floorplan reference) and outdoors (based on a GPS reference). Coverage mapping generates files in both tab-delimited and industry-standard KML format which are directly written to USB memory for analysis and mapping.
For digital LMR standards the S412E'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.
