Description
The Site Master model S331D is a hand held cable and antenna analyzer. The Site Master
model S332D is a hand held cable, antenna, and spectrum analyzer. Both models include a
keypad to enter data and a liquid crystal display (LCD) to provide graphic indications of
various measurements.
The Site Master is capable of up to 1.5 hours of continuous operation from a fully charged
field-replaceable battery and can be operated from a 12.5 Vdc source. Built-in energy con-
servation features can be used to extend battery life.
The Site Master is designed for measuring SWR, return loss, cable insertion loss and locat-
ing faulty RF components in antenna systems. The Site Master model S332D includes spec-
trum analysis capabilities including carrier-to-interference analysis.
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 contrast and backlight intensity can be adjusted.
Standard Accessories
The Handheld Software Tools PC-based software program provides a database record for
storing measurement data. Software Tools can also convert the Site Master display to a
Microsoft Windows
ä
95/98/NT4/2000/ME/XP workstation graphic. Measurements stored
in the Site Master internal memory can be downloaded to the PC using the included
null-modem serial cable. Once stored, the graphic trace can be displayed, scaled, or en-
hanced 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 Handheld Software Tools program can display measurements made with the Site Mas-
ter (SWR, return loss, cable loss, distance-to-fault, field strength, occupied bandwidth,
channel power, adjacent channel power and interference analysis) as well as providing
other functions, such as converting display modes and Smith charts. Refer to Chapter 9,
Handheld Software Tools, for more information.
