Analysers master cable and antenna installation

Cable and antenna analysers combine a wide frequency range, ease of use and high accuracy in an extremely portable, rugged design
New from Anritsu, the S311D/S312D Site Master cable and antenna analysers combine a wide frequency of 2 to 1600MHz, ease of use and high accuracy in an extremely portable, rugged design that weighs less than 2.4kg. Developed to test the RF performance of P25 and Tetra systems in the VHF/UHF, 400MHz, and 700-800MHz bands, the S311/S312D are ideally suited for land mobile radio (LMR) and public safety system technicians and engineers.

The S311D/S312D's high sensitivity allows them to identify poor connections, damaged cables, water penetration, and bad antennas.

They have special RF immunity protection so users can make highly accurate measurements, even in RF-rich environments.

The analysers use the industry-leading Site Master design that features superior frequency domain reflectometry (FDR) techniques, allowing the analysers to conduct accurate return loss/VSWR, cable loss and distance-to-fault (DTF) measurements.

The S312D can be configured to include a cable and antenna analyser, spectrum analyser, interference analyser, channel scanner, received signal strength indicator (RSSI), AM/FM demodulation, RF power meter and transmission measurement capability.

It features a best-in-class -135dBm noise floor to find low-level signals that can interfere with LMR and SMR systems.

Featuring excellent dynamic range, the S312D's transmission measurement capability can be used to accurately tune filters, duplexers, transmitter combiners, receiver multi-couplers, and tower top amplifiers.

Simple to use, the S311D/S312D have dedicated routines for critical smart measurements, including channel power, carrier-to-interference, occupied bandwidth, interference analysis, adjacent channel power (ACPR), and AM/FM demodulation.

These are increasingly critical measurements for today's wireless communication systems.

A high-accuracy power meter with a true 6GHz RMS power sensor is available as an option, and allows the S311D/S312D to conduct accurate measurements of modulated signals.

Other options available for the S311D/S312D include a power monitor, channel scanner and GPS.

Because the S311D and S312D are extremely rugged, they can easily withstand the day-to-day punishment of field use.
