S251C – Anritsu Network Analyzers
2.50GHz (High end frequency limit)

The Anritsu S251C Site Master covers the 625 MHz to 2500 MHz frequency band, and is ideally suited for field technicians working in cellular, PCS / GSM and ISM applications.

Performance enhancing design trends such as high sector to sector isolation, tower mounted amplifiers and duplexed antennas add complexities to site installation, deployment, maintenance and troubleshooting cables. To help simplify performance verification for these systems, the Anritsu Site Master â„¢ Handheld Cable and Antenna Analyzer S251C features a second test port for isolation, gain and insertion loss measurements.

Measurement capability includes return loss, cable loss and distance-to-Fault (DTF) analysis using frequency domain reflectometry (FDR) technology. The S251C also functions as a VSWR (Voltage Standing Wave Ratio) power meter. 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 Anritsu S251C SiteMaster Cable and Antenna Analyzer 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.
