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 S114B and S332B include spectrum analysis capability. 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.
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 Windowsä 95/98/NT workstation graphic. Measurements stored in the Site Mas
-
ter internal memory can be downloaded to the PC using the included null-modem serial ca
-
ble. 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 also performs DTF (Distance To Fault) and Fault
Location.
