The S331B, with frequency coverage of 25 MHz to 3300 MHz, is ideally suited for users who work in VHF, broadcasting, paging, cellular, PCS/GSM and ISM and WLL frequency bands. Both S331B and S332B can replace the S300A and the S331A Site Master models. The newly improved user interface, large VGA display, real time clock, alphanumeric trace naming, field replaceable battery and up to 517 data points and 200 trace storage make these two Site Master models ideally suited for any experience level user in commissioning and maintenance of today's wireless systems infrastructures. The S331B performs precision return loss/SWR, cable loss and distance-to-fault measurements in the presence of RF interference. An optional power monitoring is available to make power measurement quickly and easily.

The Site Master 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. All models include 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 Site Master 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 Site Master 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 Site Master Software Tools program also performs DTF (Distance To Fault) and Fault Location.
