This Operating Manual represents design, specifications, overview of
functions, and detailed operation procedure of A434L RF master, to ensure
effective and safe use of the technical capabilities of the instrument by the
user.
RF Master operation and maintenance should be performed by qualified
engineers with initial experience in operating of microwave circuits and PC.
The following abbreviations are used in this Manual:
PC –Personal Computer
DUT –Device Under Test
IF –Intermediate Frequency
CW –Continuous Wave
SWR –Standing Wave Ratio
The first edition of this Operating Manual applies directly to instruments that
have the firmware version 1.xx.

Carefully read through the following safety instructions before putting the
Analyzer into operation. Observe all the precautions and warnings provided
in this Manual for all the phases of operation, service, and repair of the
Analyzer.
The Analyzer must be used only by skilled and specialized staff or thoroughly
trained personnel with the required skills and knowledge of safety
precautions.
A434L complies with INSTALLATION CATEGORY II as well as POLLUTION
DEGREE 2 in IEC61010–1.
A434L is MEASUREMENT CATEGORY I (CAT I). Do not use for CAT II, III, or
IV.
A434L is for INDOOR USE only.
A434L is tested in stand-alone condition or in combination with the
accessories supplied by GS INSTRUMENTS CO., LTD. against the
requirement of the standards described in the Declaration of Conformity. If
it is used as a system component, compliance of related regulations and
safety requirements are to be confirmed by the builder of the system.
Never operate the Analyzer in the environment containing inflammable
gasses or fumes.
Operators must not remove the cover or part of the housing. The Analyzer
must not be repaired by the operator. Component replacement or internal
adjustment must be performed by qualified maintenance personnel only.
Never operate the Analyzer if the power cable is damaged.
Never connect the test terminals to mains.

Electrostatic discharge can damage your Analyzer when connected or
disconnected from the DUT. Static charge can build up on your body and
damage the sensitive circuits of internal components of both the Analyzer
and the DUT. To avoid damage from electric discharge, observe the
following:
-Always use a desktop anti-static mat under the DUT.
-Always wear a grounding wrist strap connected to the desktop
anti-static mat via daisy-chained 1 MΩ resistor.
-Connect clamp on the body of the Analyzer to the body of
the DUT before you start operation.
Observe all the general safety precautions related to operation of equipment
powered by mains.
The protection provided by the equipment may be impaired if the
equipment is used in a manner not specified by the manufacturer.The
definitions of safety symbols used on the instrument or in the Manual are
listed below.
Storage
Before first use store your equipment in the factory package at
environment temperature from 0 to +50 ºС and relative humidity up to
95% (at 25ºС).
After you have removed the factory package store the equipment at
environment temperature from +10 to +35 ºС and relative humidity up
to 80% (at 25ºС).
Ensure to keep the storage facilities free from dust, fumes of acids and
alkalies, aggressive gases, and other chemicals, which can cause corrosion.

1.1 Description
A large number of cell site problems are caused by the antenna system,
cable, or connectors. It is important to have the right instrument available
when either servicing or certifying cell sites for operation.
The Protek A434L RF master is a lightweight portable diagnostic tool for an
accurate detection of operational problems. The Protek A434L has all the
measurement functions necessary to accurately verify the antenna system
from VSWR to power measurements. In addition, the Protek A434L makes
distance-to-fault measurements to accurately pinpoint the fault's location.
The Protek A434L user interface is with a front keypad and a TFT color, 7-
inch display providing ease of use and control. The application specific
software allows the user to easily compare and analyze measurements and
generate comprehensive reports. The Protek A434L is equipped with a
rechargeable and infield installable lithium-ion battery providing over four
hours of operation.
