描述：
覆盖2 MHz至4 GHz频谱的Site Master手持式电缆和天线分析仪S331E型是安装，配置，维护无线基站电缆和天线系统以及对其进行故障排除的事实上的行业标准。Site Master精确，多功能，价格适中，坚固耐用且是真正的手持式设备，重量不到5磅（包括电池），非常适合具有任何经验水平的现场技术人员，他们可以使用VHF，广播，寻呼，蜂窝，PCS / GSM，3G和ISM。
S331E的测量功能包括精确的回波损耗/ SWR，电缆损耗和功率计测量。频域反射法（FDR）提供了卓越的故障距离（DTF）分析，可以准确地定位故障。获得专利的射频干扰抑制功能可在高射频活动下实现精确，可重复的测量。数据分析软件不仅可以生成专业报告，还可以评估系统趋势，问题和性能。
每个数据点的扫描速度小于2.5毫秒，可以节省技术人员的时间，并可以更轻松地实时识别间歇性问题。FlexCal宽带校准可以对电缆和天线系统进行故障排除，而无需进行多次校准和校准设置。内置的全球信号标准消除了记住系统频率和手动输入起始和终止频率值的需要。内置的平均电缆损耗无需计算电缆损耗的测量值。内置功率计选件可准确测量基站发射机的功率。高精度功率计（选件0019）可提供从50 MHz到6 GHz的真实RMS测量。
包括数据分析软件，软手提箱，可充电/可现场更换的电池，AC / DC电源，12V汽车点烟器适配器和用户指南。
Description
Site Master Handheld Cable and Antenna Analyzer Model S331E, covering the 2 MHz to 4 GHz spectrum, is the de facto industry standard for installing, provisioning, maintaining, and troubleshooting wireless base station cable and antenna systems. Accurate, versatile, affordable, rugged and a true handheld at under 5 pounds (including battery), Site Master is ideally suited for field technicians of any experience level working with VHF, broadcasting, paging, cellular, PCS/GSM, 3G and ISM.
S331E measurement capability includes precision Return Loss/SWR, Cable Loss 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.
<2.5 msec Sweep Speed Per Data Point saves the technician time and enables easier identification of intermittent problems in real time. FlexCal broadband calibration 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 0019) provides true RMS measurements from 50 MHz to 6 GHz.
Includes data analysis software, soft carrying case, rechargeable/field-replaceable battery, AC/DC power supply, 12V automobile cigarette lighter adapter and users guide.
