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 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 Reflectometry (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 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. The S311D Site Master also includes optional channelized power meter, broadband power monitor, and GPS receiver.
