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 threeconductor 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 in jury. If the instrument is to be energi zed 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 disconn ect power, discharge circuits an d 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.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitu te 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.

General Information
About This Manual
This manual is designed to be used along with the Agilent 6050A/6051A Service Manual. It includes service information
that is specific to the 60503B Module. Troubleshooting information such as fault isolation, signature analysis, and
block-level troubleshooting is the same for all modules and is found in the Agilent 6050A/6051A Electronic Load
Mainframe Service Manual. The mainframe Service Manual also explains how to safely disassemble and connect the
module to the mainframe for troubleshooting.
Typically, you will need to refer to this manual when you are performing the verification routines, locating a test point on
the component/test point diagram, referring to the schematics for additional troubleshooting information, and initializing the
module after replacing the EEPROM.
You will also need to refer to this manual for identifying and locating replaceable parts. The parts list identifies all
replaceable parts in the module, and the component/test point diagram identifies the location of all electrical parts in your
module.
Troubleshooting Precautions
Use extreme caution when troubleshooting the module when it is connected to the mainframe. AC mains
voltage is present on the exposed pins on the top edge of the mainframe GPIB board and each module
whenever the units are turned on.
Observe all standard antistatic procedures when handling the module assemblies to avoid the possibility
of electrostatic damage (refer to mainframe Service Manual) .
To reduce the risk of electrical shock when troubleshooting a defective module, make sure the GPIB board is installed in
the mainframe. Also, to make it easier to troubleshoot the module, connect the module to the GPIB board using an extender
service cable (P/N 06050-60030). This cable is included with the Service kit (P/N 06050-60004), which must be ordered
separately.
Manual Revisions
Agilent Technologies instruments are identified by a ten-character serial number such as US37250101. This manual was
written for Electronic Load Modules with serial numbers equal to and higher than those shown on the title page. If the serial
number of your module is higher than the one shown on the title page, then the module may have hardware or firmware
differences that are not covered in this manual. If there are such differences, they are documented in one or more Manual
Change sheets sent with this manual.

Module Initialization
EEPROM chip U342 on the Control Board stores the module's GPIB address and model number as well as other constants.
The EEPROM was programmed with the proper constants at the factory. If the Control board or the EEPROM chip (U342)
is replaced, the module must be reinitialized with the proper constants by programming the following commands in the
order indicated. After it has been initialized, the module must also be recalibrated as described in the Operating Manual.

Verification
Introduction
This chapter contains test procedures that check the operation and calibration of an Agilent 60503A Electronic Load
Module. The tests are performed from the front panel of an Agilent 6050A/6051A Electronic Load Mainframe with the
module installed in slot 1. The tests can also be used to determine which circuits are faulty when troubleshooting. There are
some transient, trigger, and pulse functions that require an GPIB controller and will not be verified with manual testing
from the front panel. The following tests will verify, with a high level of confidence, that the module is operating properly
without testing all of its capabilities.
At the end of this chapter are performance record tables where actual measured values can be recorded.
Test Equipment Required
Table 2-1 lists the test equipment required to perform the tests in this chapter. Test setups for the tests are shown in Figures
2-1 through 2-3. Make sure the sense switch on the rear of the module is se t to the LCL position since local sensing is used
in all of the test setups. Use adequate wire gauge when making connections (see Chapter 3 in the Operating Manual).
Note The Electronic Load must pass the selftest at power turn-on before the following tests can be performed.
If the unit fails selftest, refer to the overall troubleshooting procedures in the mainframe Service Manual.

Diagrams
Schematic Diagrams
Schematic diagrams and component location diagrams are provided for the Control board as well as the Power board on two
foldout pages. Two schematic diagrams of the Power board are included in Figure 4-2 on the first foldout; three schematic
diagrams of the Control board are included in Figure 4-4 on the second foldout. Table 4-1 lists the notes that apply to both
the Control board and Power board schematic diagrams.
Table 4-2 lists, alphabetically, all of the signal names that appear on the schematic, along with a brief description of the
signal's function. To help you locate where signals come from and go to, Table 4-1 lists the coordinates for each appearance
of a signal on each sheet of the schematic. Coordinates printed in BOLD indicate the signal origin. On the Control board for
example, when ACLR* is active, it clears the analog circuits. ACLR* originates in area 4D of sheet 1 and also appears in
area 2B of sheet 3.
Table 4-1. Schematic Diagram Notes
1. All resistors are in ohms ± 1%, 1/8 W unless otherwise specified.
2. All capacitors are in microfarads unless otherwise specified.
3. All unmarked capacitors are 0.047µF.
4. An asterisk negates a signal name. For example,
5. Signal lines that are terminated by flags continue on other sheets, and may also go to other locations on the same sheet.
Table 4-2 documents all signal terminations on the schematics. Note that flags do not indicate signal flow direction.
appears on the schematic as CS2*.
CS2
Example:
6. Unterminated signal lines go to at least one other location of the same schematic sheet.
Example: SPCLR*
7. Heavy signal lines represent multiple-wire data buses.
8. Unless otherwise noted, bias connections to IC packages are as follows:
14-pin packages pin 7 pin 14
16-pin packages pin 8 pin 16
20-pin packages pin 10 pin 20
9. Values in brackets [ ] apply to model 60507B.

Component Location Diagrams
Each foldout includes a component locations diagram with a look-up table for locating electrical components. Figure 4-1
gives the component locations for the Control board and Figure 4-3 gives the component locations for the Power board. The
coordinates in the look-up table under each diagram reference the grid on the diagram and give the location of some point
on each component to within 1/10 of a unit. The mainframe Service Manual gives several examples of how to use the table.
The component locations diagram also indicates specific troubleshooting test point locations. The test points are described
in Chapter 3 of the mainframe Service Manual and are used in various troubleshooting procedures described in that chapter.
