Anritsu S312D Overview

The Site Master is the ideal instrument for Land Mobile Radio (LMR) and Public Safety System technicians and engineers testing the RF performance of P25 and TETRA radios in the VHF/UHF, 400 MHz, 700 MHz, and 800 MHz bands.

The S312D can be configured to be equipped with a cable & antenna analyzer, spectrum analyzer, interference analyzer, channel scanner, Received Signal Strength Indicator (RSSI), AM/FM demodulation, RF power meter, and GPS receiver.

The high performance 25 MHz to 1600 MHz cable & antenna analyzer can be used to sweep cables and antenna systems. Option 2 extends the lower frequency range to 2 MHz. Frequency Domain Reflectrometry (FDR) based Return Loss and VSWR measurements are used to characterize antenna systems. The Distance-To-Fault (DTF) measurement can easily spot poor connections, contamination, damaged cables, and water penetration.

The fast sweep speed results in significant time savings for the technicians. FlexCal broadband calibration allows troubleshooting cable and antenna systems without multiple calibrations and calibration setups. Patented RF interference rejection enables accurate, repeatable measurements in the presence of high RF activity.

The S312D combines the high performance cable & antenna analyzer with a fully functional spectrum analyzer. The excellent DANL of -135 dBm makes this instrument ideal for finding low level signals which can interfere with LMR systems.

The excellent dynamic range can be utilized in the transmission measurement option and be used to view and adjust the RF performance of critical RF devices including filters, duplexers, transmitter combiners, receiver multi-couplers and tower top amplifiers.

The High Accuracy Power Meter provides true RMS measurements from 50 MHz to 6 GHz. 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 S312D model Site Master Handheld Cable and Antenna analyzer includes data analysis software, soft carrying case, rechargeable/field-replaceable battery, AC/DC power supply, 12V automobile cigarette lighter adapter and users guide.
