The S412E LMR Master is an integrated multi‑functional test instrument that eliminates the need to carry and learn multiple test sets. The LMR Master combines a high performance receiver/spectrum analyzer with a vector network analyzer. The S412E can optionally be configured to include Coverage Mapping for P25/P25p2, NXDN™, dPMR, DMR MOTOTRBO™, PTC-ITCR, PTC-ACSES, and TETRA (LMR Digital Demodulation). Other available options include Interference Analyzer with mapping, Channel Scanner, AM/FM/PM Analyzer, Vector Voltmeter, Fixed and Mobile WiMAX™, GSM/GPRS/EDGE, FirstNet LTE (RF, Modulations, and Over-the-Air), and High Accuracy Power Meter.
The LMR Master includes a CW and NBFM Signal Generator with a 500 kHz to 1.6 GHz frequency range and 0 dBm (1 mW) maximum power level. In many available LMR modes (P25/P25p2, NXDN, TETRA, DMR, PTC-ITCR, or PTC-ACSES), the LMR Master signal generator can create mode-specific patterns, CW, 1 kHz AM, and 1 kHz FM signals with adjustable frequency and power levels.
The LMR Master spectrum analyzer, NBFM, P25/P25p2, NXDN, TETRA, DMR, dPMR, and PTC-ITCR and PTC-ACSES frequency ranges are expanded to 6 GHz with Option 6. The VNA frequency range is expanded to 6 GHz with Option 16. Additional options include a Bias Tee for TMA testing and a GPS receiver. Details on configuration and available options are provided in the LMR Master Technical Data Sheet.
The bright, 8.4 inch, TFT backlit, LCD color display provides easy viewing in many lighting conditions. Use the touch screen to navigate menus and use the keypad to enter data. All LMR Master models are equipped with a field-replaceable Li‑Ion battery delivering more than three hours of battery life.
The internal memory is large enough to store approximately 2,000 traces or setups. Measurements and setups can also be stored in a USB memory device or transferred to a PC by using the included USB cable or through Ethernet. The amount of external USB memory is limited only by the size of the USB memory device. Use Line Sweep Tools (LST) for certain VNA measurements and Master Software Tools (MST) for spectral analysis measurements (refer to Anritsu PC Software Tools for an overview of these software tools).
Note
Not all after‑market USB memory devices are compatible with the LMR Master. Many drives come with a second partition that contains proprietary firmware. This partition must be removed. Only one partition is allowed. Refer to the individual drive manufacturer for instructions on how to remove it. Some drives can be made to work by reformatting them with the FAT32 format.
