The NEW S311D/S312D Site Master™ cable and antenna analyzers combine wide frequency coverage of 2 MHz to 1600 MHz, ease of use, and high accuracy in an extremely portable, rugged design that weighs less than 2.5 kg (5 lbs). Developed to test the RF performance of P25 and TETRA systems in the VHF/UHF, 400 MHz, and 700-800 MHz 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 analyzers utilize the industry-leading Site Master design that features superior Frequency Domain Reflectometry (FDR) techniques, allowing the analyzers 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 analyzer, spectrum analyzer, interference analyzer, channel scanner, Received Signal Strength Indicator (RSSI), AM/FM demodulation, RF power meter, and transmission measurement capability. It features a best-in-class -135 dBm 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.
