Description
The Site Master model S331D is a hand held cable and antenna analyzer. The Site Master
model S332D is a handheld cable, antenna, and spectrum analyzer. Both models include a
keypad to enter data and a standard daylight-viewable color TFT display 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 Return Loss, SWR, and Cable Loss of cable and
antenna systems from 25 MHz to 4 GHz. Option 2 and Option 16 extend the frequency
range of the cable and antenna analyzer to 2 MHz and 6 GHz respectively. Dis

tance-To-Fault (DTF) measurements can be used to locate the precise location of a fault
within the feedline system. The Site Master model S332D includes Spectrum Analysis (100
kHz - 3 GHz) and has dedicated routines for common one-button measurements. Options
available with the S331D or S332D include 2-port Transmission Measurements, Bias Tee,
narrow band or wide band power meter, Channel Scanner, Interference Analyzer, GPS, and
T1/E1 Analyzer measurements.
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 Windowsä 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.
