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

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

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.
