Anritsu Company has introduced an NBFM Mode for its LMR Master S412E
handheld analyzer that allows users to conduct fast,
accurate measurements on Narrowband Analog FM (NBFM) Land Mobile Radio (LMR)
systems used by public safety agencies, utilities, and other private
organizations. With the new mode, the LMR Master S412E extends its measurement
and analysis capabilities, and provides field technicians and engineers who
deploy, install, and maintain LMR networks with a handheld test solution that
helps ensure optimum system performance.
The LMR Master
S412E's NBFM Mode, which is now standard on all new instruments
and can be retrofitted to existing instruments via a standard no-cost firmware
upgrade, can automatically detect the carrier frequency of an unknown
transmitter, tune to that frequency, and analyze the transmitter's deviation,
CTCSS/DCS tone, occupied bandwidth and other parameters. With the NBFM Mode,
the LMR Master S412E can support analog LMR systems that use either 12.5 kHz
channels or 25 kHz channels, making it a flexible single-instrument solution
that can address a variety of networks.
The NBFM Mode expands the capabilities of the LMR Master S412E,
which can also support P25, NXDN, and DMR/MotoTRBO™ systems. The LMR Master
S412E significantly reduces the number of tools field technicians and engineers
must carry, thereby saving time and money while ensuring accuracy. It features
a built-in vector network analyzer (VNA) that delivers excellent transmission
dynamic range of > 100 dB, so users can view and adjust the RF performance
of RF devices including filters, duplexers, transmitter combiners, receiver
multi-couplers and tower-mounted amplifiers. VNA measurements are quickly
displayed and updated on the LMR Master
S412E's 8.4" high-resolution TFT touchscreen which
features a fast 850 μs/point sweep speed.
A built-in spectrum analyzer with excellent DANL of -152 dBm,
dynamic range of > 95 dB (both 10 Hz RBW @ 2.4 GHz) and a third-order
intercept of greater than +16 dBm makes the LMR Master S412E the ideal tool for
finding low-level signals that can interfere with LMR systems, even in the
presence of strong nearby carriers typically found at LMR repeater sites. It
features an industry-leading low phase-noise reference oscillator (< -110
dBc/Hz typical @ 10 kHz offset) that allows precise measurement of NBFM, P25,
NXDN, and DMR system performance including emission masks, bit-error rate
(BER), and modulation fidelity or error-vector magnitude (EVM).
The LMR Master S412E also
features an optional high-accuracy power meter that provides true RMS
measurements from 50 MHz to 6 GHz using a selection of external sensors,
including inline sensors capable of handling up to 150 watts. It is the ideal
solution for making accurate measurements of both CW and modulated signals.
The LMR Master S412E has delivery of 4-6 weeks ARO.
