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 violates safety
standards of design, manufacture, and intended use of the instrument. Agilent Technologies assumes no liability for the
customer's failure to comply with these requirements.
BEFORE APPLYING POWER.
Verify that the product is set to match the available line voltage and the correct fuse is installed.
GROUND THE INSTRUMENT.
This product is a Safety Class 1 instrument (provided with a protective earth terminal). To minimize shock hazard, the instrument chassis
and cabinet must be connected to an electrical ground. The instrument must be connected to the ac power supply mains through a three-
conductor power cable, with the third wire firmly connected to an electrical ground (safety ground) at the power outlet. For instruments
designed to be hard-wired to the ac power lines (supply mains), connect the protective earth terminal to a protective conductor before any
other connection is made. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will
cause a potential shock hazard that could result in personal injury. If the instrument is to be energized via an external autotransformer for
voltage reduction, be certain that the autotransformer common terminal is connected to the neutral (earth pole) of the ac power lines
(supply mains).
FUSES.
Only fuses with the required rated current, voltage and specified type (normal blow, time delay, etc.) should be used. Do not use repaired
fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made by qualified
service personnel. Do not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even
with the power cable removed. To avoid injuries, always disconnect power, discharge circuits and remove external voltage sources before
touching components.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person capable of rendering first aid and resuscitation, is present.
DO NOT EXCEED INPUT RATINGS.
This instrument may be equipped with a line filter to reduce electromagnetic interference and must be connected to a properly grounded
receptacle to minimize electric shock hazard. Operation at line voltages or frequencies in excess of those stated on the line rating label
may cause leakage currents in excess of 5.0 mA peak.
SAFETY SYMBOLS.
Instruction manual symbol: the product will be marked with this symbol when it is necessary for the user to refer to the
instruction manual (refer to Table of Contents) .
Indicates hazardous voltages.
Indicate earth (ground) terminal.
The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like, which, if not correctly
performed or adhered to, could result in personal injury. Do not proceed beyond a WARNING sign until the
indicated conditions are fully understood and met.
The CAUTION sign denotes a hazard. It calls attention to an operating procedure, or the like, which, if not correctly
performed or adhered to, could result in damage to or destruction of part or all of the product. Do not proceed
beyond a CAUTION sign until the indicated conditions are fully understood and met.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the
instrument. Return the instrument to an Agilent Technologies Sales and Service Office for service and repair to ensure that safety features
are maintained.
Instruments which appear damaged or defective should be made inoperative and secured against unintended operation until they can be
repaired by qualified service personnel.

Introduction
Scope
This manual contains information for troubleshooting and repairing the Agilent Technologies 6060B and 6063B Electronic
Load to the component level. Replaceable parts lists and circuit diagrams are also provided. Verification procedures are
included to aid in determining the performance level either before or after repair. Calibration procedures and specifications
for the Electronic Load are included in the Operating Manual.
Related Documents
The following documents, shipped with each Electronic Load, are referenced in this manual:
Document Relevant Information
Agilent 6060B/6063B Operating Manual Agilent Part No. Calibration procedures, local & specifications
5951-2826 remote operation.
Electronic Load Family Programming Reference Guide SCPI programming, status reporting
Agilent Part No. 06060-90005
It is assumed that you are familiar with, or can obtain, the information in the above documents.
Firmware Revisions
Some information in this manual, and S.A. (signature analysis) information in particular, is associated with specific versions
of the Electronic Load firmware. Each Electronic Load returns the revision number of its primary interface firmware in
response to the "*IDN?" query. Both primary and secondary interface ROMs have a label that also specifies the firmware
revision. See "Signature Analysis" in Chapter 3.
Manual Revisions
Agilent instruments are identified by a two-part, ten-character serial number, such as 2847A-00101. The first five characters
(e.g. 2847A) are the serial prefix, which is the same for all identically made instruments. The last five digits (e.g. 00101) is
a unique serial number assigned to each instrument. If a significant design change is made, the prefix changes but the last
five numbers continue in sequence.
This manual was written for Electronic Loads with the same serial prefix and with serial numbers equal to or higher than the
ones shown on the title page. If the prefix number of your Electronic Load is higher than the one on the title page, then the
Electronic Load was made after publication of the manual and may have hardware and/or firmware differences not covered
in this manual. If there are such differences, they are documented in one or more "Manual Changes" sheets sent with the
manual.

Safety Considerations
The Electronic Load is a Safety Class 1 instrument, that has a protective earth terminal. Refer to the Safety Summary page
at the beginning of this manual for a summary of general safety procedures and the meaning of safety symbols in the manual
and on the Electronic Load.
Electrostatic Discharge
The Electronic Load has components that can be damaged by ESD (electrostatic discharge). Failure to
observe standard, anti-static practices can result in serious degradation of performance, even when
complete failure does not occur.
When working on the Electronic Load, observe all standard, anti-static work practices. These include, but are not limited to:
