Anritsu SiteMaster S251B Broadband Two-Port Transmission Line and Antenna Analyzer
625 Mhz to 2500 Mhz Frequency Range With Option 5 (RF Watt Meter Power Monitor) & 10A (Bias Tee)
The Site Master S251B is a broadband two-port transmission line and antenna analyzer that performs return loss (SWR), cable loss and distance-to-fault measurement for cellular, PCS/GSM and ISM market applications.
Site Master s patented high RF interference rejection enables the S251B to accurately measure cable and antenna systems in the presence of high RF activity. In addition, the high dynamic range (>80 dB) enables the S251B to perform antenna-to-antenna isolation measurements.
Selectable output levels of +6 dBm or 30 dBm and optional built-in Bias Tee provide the S251B with a convenient means of verifying Tower Mounted Amplifier (TMA) gain before and after installation. Status of applied voltage and current load indicate the operation and function of the TMA.
The Site Master Software Tools supplied with each S251B operates with Windows 95, Windows 98, and Windows NT. Software Tools can download traces and cable parameters to S251B via the RS-232 serial port.
