Anritsu S331A Cable and Antenna Analyzer 25 MHz - 3.3 GHz
Description
The Site Master S331A 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 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.
