Safety Precautions
Remove Power
Observe general safety precautions. Do not open the instrument with
the power on.
Safety Earth Ground
An uninterruptible safety earth ground must be supplied from the
main power source to the instrument. Grounding one conductor of a
two conductor power cable is not sufficient protection. Serious injury
or death can occur if this grounding is not properly installed.
Safety Symbols
Warning notes call attention to a procedure, which if not correctly
performed, could result in personal injury.
Caution notes call attention to a procedure, which if not correctly
performed, could result in damage to the instrument.
The caution symbol appears on the equipment indicating
there is important information in the instruction manual
regarding that particular area. See page 72 for specific
cautions.
☞
NOTE: Calls attention to supplemental information.
Warning Statements
The following safety warnings appear in the text where there is
danger to operating and maintenance personnel, and are repeated
here for emphasis.
The SA-BATPAK is shipped charged. Be careful when removing the
safety cap, 12Vdc @ 2.0 AH/20 hour rate can be present inside the
receptacle. Do not touch the inside of the receptacle. The possibility
of an electric shock exists.

WARNING
during a storm that has the potential to produce lightning. The
possibility exists for electrical shock.
WARNING
When using the ac adapt er, only connect the plug to a properly
grounded receptacle. Serious injury or death can occur if grounding
is not properly installed.
Caution Statements
The following equipment cautions appear in the text and are repeated
here for emphasis.
CAUTION
Harsh or abrasive detergents, and some solvents, can damage the
display unit and information on the labels.
CAUTION
When using a Bird 5011, do not exceed 2 W average or 125 W peak
power for 5 µs. Doing so will render the sensor inoperative.
CAUTION
+22 dBm max. input
Do not apply RF power to Antenna Test Port. Exceeding the
maximum input will damage the Site Analyzer.

Chapter 1 Introduction
The Bird Site Analyzer is a multifunction test
instrument for use in installation and maintenance of
wireless syst e ms.
Antenna systems are tested by using a Site Analyzer
to measure match conditions. Data is graphed at 238
points across a user-specified frequency band or
distance range. Transmitter systems are tested by
using a Site Analyzer and a Bird power sensor to
measure RF power. Data is displayed as power or
match efficiency, depending on the sensor.

a minimum of 3 hours of cont inuous usage. Recharg ing
time, from a full discharge, is approximately 4 hours.
☞
NOTE: When the unit is received the battery may
not be fully c harg ed. An ac adap te r shou ld be u sed
when operating the unit for the first time.
The battery gauge indicates the approximate battery
life remaining. At
“LO”. When using an external power source, a power
cord symbol replaces the battery gauge.
The Bird Site Analyzer can be operated using an ac
adapter or a 12V automobile cigarette lighter adapter.
Using these will also charge the internal battery.
When using the ac ada pt er, only conne ct the plug to
a properly grounded receptacle. Serious injury or
death can occur if not properly grounded.
The SA-BATPAK is a n op ti onal ex te rnal ba tte ry pack.
This will operate the unit for approximately 2 hours.
The liquid acid gel battery will fully charge, from a full
discharge, in about 6-8 hours.

Chapter 4 Measure Match Mode
This measurement verifies and monitors the match
conditions in the antenna system at various
frequencies. The results are shown on an x-y graph.
Frequency is shown on the x-axis while return loss,
cable loss, or VSWR is shown on the y-axis.
☞
NOTE: For best results, set the frequency and
calibrate the Site Analyzer immediately before
taking measurements.
