1. SAFETY INSTRUCTIONS
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.
A333 complies with INSTALLATION CATEGORY II as well as POLLUTION
DEGREE 2 in IEC61010-1.
A333 is MEASUREMENT CATEGORY I (CAT I). Do not use for CAT II, III, or
IV.
A333 is for INDOOR USE only.
A333 is tested with stand-alone condition or with the combination with the
accessories supplied by Protek 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 use the Analyzer without secure grounding. Operation is permitted only with
protective earth connection by the supplied power cable to a 3-pin grounded power
outlet.
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.
Observe all the general safety precautions related to operation of equipment powered
by mains.
The definitions of safety symbols used on the instrument or in manuals are listed
below.
Refer to the Manual if the instrument is marked with this
symbol. .

2. GENERAL OVERVIEW
2.1. Description
A333 Network Analyzer has been designed for use in the process of development,
adjustment and testing of various electronic devices in industrial and laboratory
facilities, including operation as a component of an automated measurement system.
A333 is designed for operation with external PC, which is not supplied with the
Analyzer.
2.2. Specifications
