Anritsu Site Master S251ACable & Antenna Analyzer SiteMaster

Description

The Anritsu S251A Site Master is the instrument of choice for transmission line/antenna installation and maintenance. It is the best way to reduce maintenance expenses and improve quality. It replaces stacks of heavy, expensive and complex test equipment. Site Master's frequency domain reflectometry technique allows it to find problems before they become catastrophic faults thereby creating a huge cost savings. The Anritsu S251A Site Master uses a keypad to enter data and a liquid crystal display (LCD) to provide a graphical indication of S21, SWR, or RL over the selected frequency range. The Anritsu S251A Site Master has a built-in distance-to-fault (DTF) capability and is capable of up to two hours of continuous operation from a fully charged internal battery and can be operated from a 12.5 dc source (which will also simultaneously charge the battery). Built-in energy conservation features can be used to extend battery life over an eight-hour work day.
