neously charge the battery). 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 capability is available as an option. The displayed
trace can be scaled and/or enhanced with settable frequency markers
and/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
A PC based software program (called Software Tools) provides an on-
line database record for storing measurement data. Site Master Soft-
ware Tools can also convert the Site Master display to a Microsoft
Windows 3.x graphic. Measurements stored in the Site Master internal
memory are down-loaded to the PC using the included serial cable.
This null-modem serial cable connects between the Serial Interface
connector on the Site Master and a Com Port on a DOS/Windows-
based PC. Once stored, the graphic trace can then be displayed, scaled,
and/or enhanced with markers and limit lines. Historical graphs can be
overlaid with current data by using the PC’s mouse in “drag-n-drop”
fashion. The underlying data can be extracted and used in spreadsheets
or for other analytical tasks.
The Software Tools program also performs DTF (Distance To Fault) or
Fault Location by clicking on the appropriate icon.
