 Anritsu  Site master S331D

S331D measurement capability includes precision Return Loss/SWR, Cable Loss and optional T1/E1 and power meter measurements. Frequency Domain Reflectometry (FDR) provides superior Distance to Fault (DTF) analysis to locate faults accurately. Patented RF interference rejection enables accurate, repeatable measurements in the presence of high RF activity. Data analysis software enables assessment of system trends, problems, and performance in addition to professional report generation.

<3.5 msec Sweep Speed Per Data Point saves the technician time and enables easier identification of intermittent problems in real time. FlexCal broadband calibration 25 MHz to 4 GHz allows troubleshooting cable and antenna systems without multiple calibrations and calibration setups. Built-In Worldwide Signal Standards eliminates the need to remember system frequencies and manually input the start and stop frequency values. Built-In Average Cable Loss eliminates the need to calculate a measured cable loss value. Built-In Power Meter Option measures the base station transmitter power accurately. The High Accuracy Power Meter (option 19) provides true RMS measurements from 50 MHz to 6 GHz.

The S331D 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.
