ANRITSU S251C

Covering the 625 MHz to 2500 MHz frequency band, the Site Master S251C site management tool is designed to accurately locate and identify cable and antenna system faults and conduct isolation and gain measurements. This model is ideally suited for users working in cellular, PCS/GSM and ISM applications.

Measurement capability includes return loss, VSWR, cable loss and distance-to-Fault (DTF) analysis. In addition, the S251B features a second port for antenna isolation and gain measurement. A selectable +6 dBm or +30 dBm output and optional Bias Tee enables users to conveniently verify Tower Mounted Amplifier (TMA) gain before and after installation. The S251C's patented RF interference rejection feature and high dynamic range(>90 dB) enables the S251C to accurately measure antenna-to-antenna isolation in the presence of high RF activity. Data Analysis Software enables assessment of system trends, problems and performance in addition to professional report generation. An optional power monitor is available to make power measurements quickly and easily.

The S251C includes data analysis software, soft carrying case, rechargeable battery, AC/DC power supply, 12.5V automobile cigarette lighter adapter and users guide. The S251C replaces the former S251B models.
