Anritsu S331C
Anritsu Site Master S331C Antenna, Cable Analyzer
Description
The Anritsu S331C Site Master is a hand held SWR/RL (standing wave ratio/return loss), and Distance-To-Fault (DTF) measurement instrument.
Anritsu S331C includes a built-in synthesized signal source. S331C includes a keypad to enter data and liquid crystal display (LCD) to provide graphic indications of SWR or RL over the selected frequency range and selected distance.
The S331C Site Master can work up to 2.5 hours of continuous operation from a fully charged field-replaceable battery. S331C 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 S331C Site Master is designed for measuring various parameters such as SWR, return loss, or cable insertion loss and locating faulty RF components in antenna systems. Power monitoring (Option) is available.
The displayed trace can be scaled or enhanced with frequency markers or limit lines. 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.
