Description
The Site Master 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 conser- vation 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 lo- cating faulty RF components in antenna systems. Power monitoring is available as an op- tion. Site Master models S114C and S332C include spectrum analysis capability. 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.
Standard Accessories
The Software Tools PC-based software program provides a database record for storing measurement data. Site Master Software Tools can also convert the Site Master display to a Microsoft Windows 95/98/NT4/2000/ME workstation graphic. Measurements stored in the Site Master internal memory can be downloaded to the PC using the included null-mo- dem serial cable. Once stored, the graphic trace can be displayed, scaled, or enhanced with markers and limit lines. Historical graphs can be overlaid with current data, and underlying data can be extracted and used in spreadsheets or for other analytical tasks.
The Site Master Software Tools program can display all of the measurements made with the Site Master (SWR, return loss, cable loss, distance-to-fault) as well as providing other func- tions, such as converting display modes and Smith charts. Refer to Chapter 7, Software Tools, for more information.
