Troubleshooting Guide

Caution

Safety Summary

The following general safety precautions must be observed during all phases of

operation, service, and repair of this instrument. Failure to comply with these

precautions or with specific WARNINGS elsewhere in this manual may impair

the protection provided by the equipment. Such noncompliance would also

violate safety standards of design, manufacture, and intended use of the

instrument. Keysight Technologies assumes no liability for the customer’s

failure to comply with these precautions.

Do not exceed the operating input power, voltage, and current level and signal

type appropriate for the instrument being used, refer to your instrument’s

Function Reference.

Electrostatic discharge (ESD) can damage the highly sensitive microcircuits in

your instrument. ESD damage is most likely to occur as the test fixtures are

being connected or disconnected. Protect them from ESD damage by wearing

a grounding strap that provides a high resistance path to ground. Alternatively,

ground yourself to discharge any static charge built-up by touching the outer

shell of any grounded instrument chassis before touching the test port

connectors.

The E5072A complies with INSTALLATION CATEGORY II as well as

POLLUTION DEGREE 2 in IEC61010-1. The E5053A is an INDOOR USE

product.

The LEDs in the E5072A are Class 1 in accordance with IEC60825-1,

CLASS 1 LED PRODUCT

This equipment is MEASUREMENT CATEGORY I (CAT I). Do not use for CAT

II, III, or IV.

Safety Summary

• Ground the Instrument

To avoid electric shock, the instrument chassis and cabinet must be

grounded with the supplied power cable’s grounding prong.

• Do NOT Operate in an Explosive Atmosphere

Do not operate the instrument in the presence of inflammable gases or

fumes. Operation of any electrical instrument in such an environment

clearly constitutes a safety hazard.

• Keep Away from Live Circuits

Operators must not remove instrument covers. Component replacement

and internal adjustments must be made by qualified maintenance

personnel. Do not replace components with the power cable connected.

Under certain conditions, dangerous voltage levels may remain even after

the power cable has been disconnected. To avoid injuries, always

disconnect the power and discharge circuits before touching them.

• DO NOT Service or Adjust the Instrument Alone

Do not attempt internal service or adjustment unless another person,

capable of rendering first aid and resuscitation, is present.

• Do NOT Substitute Parts or Modify the Instrument

To avoid the danger of introducing additional hazards, do not install

substitute parts or perform unauthorized modifications to the instrument.

Return the instrument to a Keysight Technologies Sales and Service Office

for service and repair to ensure that safety features are maintained in

operational condition.

• Dangerous Procedure Warnings

Warnings, such as the example below, precede potentially dangerous

procedures throughout this manual. Instructions contained in the warnings

must be followed.

This equipment is tested with stand-alone condition or with the

combination with the accessories supplied by Keysight Technologies

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.

Dangerous voltage levels, capable of causing death, are present in this

instrument. Use extreme caution when handling, testing, and adjusting

this instrument.

Troubleshooting Guide

1 Troubleshooting

This chapter provides the procedure to isolate a faulty assembly in the E5072A.

Introduction

These servicing instructions are for use by qualified personnel only. To

avoid possible electrical shock, do not perform any servicing unless you

are qualified to do so.

The opening of covers or removal of parts is likely to expose dangerous

voltages. Disconnect the instrument from its power supply beforehand.

Many of the assemblies in the instrument are very susceptible to damage

from ESD (electrostatic discharge). Perform the following procedures only

at a static-safe workstation and wear a grounding strap.

DO NOT operate without following instructions. Programs or files in the

instrument may be broken.
