Anritsu S331 Network Analyzer
The Anritsu S331 Site Master is a hand held SWR/RL(standing wave ratio/return loss) and Distance-To-Fault measurement instrument that includes a built-in synthesized signal source.
The S331 uses a keypad to enter data and a liquid crystal display (LCD) to provide a graphical indication of SWR or RL over the selected frequency range.
The Site Master S331 have a built-in distance-to-fault capability. The Site Master S110 and S330, as well as models S111 and S331, allow measurement data to be converted to Fault Location via the companion Software Tools program.
The S331 is capable of up to two hours of continuous operation from a fully charged internal battery.
S331 can also 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.
The S331 is designed for measuring SWR, return loss, or cable insertion loss and locating faulty RF components in antenna systems.
The displayed trace can be scaled and/or enhanced with settable frequency markers and/or a limit line. A menu option provides for an audible beep when the limit value is exceeded. To permit use in low-light environments, the LCD can be back lit using a front panel key.
