Anritsu S331B

The Anritsu S331B is a hand held SWR/RL (standing wave ratio/return loss), and Distance-To-Fault (DTF) measurement instrument that includes a built-in synthesized signal source.

Anritsu S331B model includes a keypad to enter data and a liquid crystal display (LCD) to provide graphic indications of SWR or RL over the selected frequency range and selected distance.

The S331B is capable of up to 2.5 hours of continuous operation from a fully charged field-replaceable battery and can be operated from a 12.5 dc source.

Built-in energy conservation features can be used to extend battery life over an eight-hour work day.

The S331B is designed for measuring SWR, return loss, or cable insertion loss and locating faulty RF components in antenna systems. Power monitoring is available as an option.

The displayed trace can be scaled or enhanced with frequency markers 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.

The Software Tools PC-based software program provides a database record for storing measurement data. The Site Master Software Tools program also performs DTF (Distance To Fault) and Fault Location.

The Nickel Metal Hydride (NiMH) Battery supplied with the S331B Site Master is shipped in a discharged state. Before using the S331B, the internal battery must first be charged for three hours, either in the Site Master or in the optional battery charger
