The S412E is the second generation solution from Anritsu for installing and maintaining public safety systems. Built on the Anritsu ninth generation handheld platform, the S412E combines a high performance receiver / spectrum analyzer with the 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.
The S412E comes equipped with a vector network analyzer and spectrum analyzer, and may be optionally equipped with a Spectrogram / Interference Analyzer, Programmable Channel Scanner, AM/FM/PM Modulation Analyzer, external High-Accuracy RF Power Meter, GPS receiver, Distance Domain for cable analysis, and Vector Voltmeter. The S412E comes standard with either a P25, NXDN, or DMR Analyzer, and may be optionally equipped with additional standards such as LTE for FCC-mandated broadband public safety systems, and WiMAX for intersite backhaul. Coverage Mapping (both indoor and outdoor) is optionally available for AM/FM/P25/NXDN/DMR system analysis.
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.
The S412E vector network analyzer offers excellent transmission dynamic range (> 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 fast 850 μs/point sweep speed of the S412E.
The S412E combines a high performance vector network analyzer with a fully functional spectrum analyzer. The excellent DANL of -152 dBm (RBW = 10 Hz, Atten = 0 dB, f < 2.4 GHz) makes this instrument ideal for finding low level signals which can interfere with LMR systems. The spectrum analyzer coverage can be extended to 6 GHz with option 6.
The High Accuracy Power Meter provides true RMS measurements from 50 MHz to 6 GHz using an external sensor. 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 users guide.
