Safety Summary
The following general safety precautions must be observed during all phases of operation 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.
GENERAL
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective features of this
product may be impaired if it is used in a manner not specified in the operating instructions.
Any LEDs used in this product are Class 1 LEDs as per IEC 825-1.
This ISM device complies with Canadian ICES-001. Cet appareil ISM est conforme à la norme NMB-001 du Canada.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use in an installation category II, pollution degree 2 environment. It is designed to
operate at a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the specifications tables for
the ac mains voltage requirements and ambient operating temperature range.
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage, the correct fuse is installed, and all safety precautions are
taken. Note the instrument’s external markings described unde r "Safety Symbols".
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical ground. The instrument
must be connected to the ac p ower 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
(earthed pole) of the ac power lines (supply mains).
ATTENTION: Un circuit de terre continu est essentiel en vue du fonctionnement sécuritaire de l’appareil. Ne
jamais mettre l’appareil en marche lorsque le conducteur de mise … la terre est d‚branch‚.
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 data plate may cause leakage currents in excess of 5.0 mA peak.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized
modifications 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 that appear damaged or defective should be made inoperative and secured against unintended operation until
they can be repaired by qualified service personnel.

General Information
Introduction
This manual contains specifications, installation instructions, and operating instructions for System Power Supply Models:
Agilent 6030A, 6031A, 6032A, 6033A, 6035A, and 6038A. Refer to "Related Documents" for other information
concerning these products.
Description
This system power supply is an autoranging GP-IB power supply. It uses power MOSFETs in a 20 kHz switching converter
to provide an autoranging output characteristic with laboratory performance. Output voltage and current are continuously
indicated on individual meters. LED indicators show the complete operating state of the unit. Front-panel controls allow the
user to set output voltage, current and overvoltage protection trip levels. Overvoltage p rotection (OVP) protects the load by
quickly and automatically interrupting energy transfer if a preset trip voltage is exceeded. Foldback protection can be
selected to disable the power supply output if the unit switches from Constant Voltage (CV) to Constant Current (CC) mode
or vice-versa.
The power supply can be both a listener and talker on the GP-IB, and can be programmed directly in volts and amps. Power
supply status can be read over the GP-IB, and the power supply can be instructed to request service for any of ten
conditions. Upon command, the power supply will measure its output voltage, output current, or OVP trip voltage and put
the value on the GP-IB. New output values can be put on hold and triggered later, allowing the controller to synchronize
multiple power supplies at one time.
The following parameters and features can be controlled via the GP-IB:
•
Output voltage setting (12 bits)
•
Output current setting (12 bits)
•
Trigger (update output)
•
Output disable/enable
•
OVP reset
•
"Soft" voltage and current limits
•
Status reporting
•
Service request capability
•
Foldback protection
•
Output voltage measurement (12 bits)
•
Output current measurement (12 bits)
•
OVP setting measurement
•
Machine state initialization
• 16 machine state presets
• Self test
Output connections are made to rear-panel screw-on terminals. Either the positive or negative output terminal may be
grounded or the output may be floated up to + 550 Vdc (including output voltage) from chassis ground. Output voltage can
be locally or remotely sensed.
The power supply is fan cooled and is packaged in an Agilent Technologies System ll-compatible modular enclosure which
is sturdy, attractive and provides easy access for servicing.
General Information
11
A fault indicator (FLT) and remote inhibit (INH) circuit provides additional shutdown protection, should either the GP-IB
and/or controller fail.
The FLT circuit provides the user with a means of knowing the status of any unmasked fault register bit independently of
the SRQ function available through the GP-IB. You don’t have to rely on the controller to inform you of a fault within the
power supply.
The INH circuit (which is also independent of the GP-IB) controls the RI bit in the fault registers, and provides a way to
disable the supply remotely (i.e. a "panic button’’). This gives you a means to bypass the controller and/or GP-IB to disable
the supply.
Safety Considerations
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The instrument and this manual
should be reviewed for safety markings and instructions before operation. Refer to the Safety Summary page at the
beginning of this manual for a summary of general safety information. Safety information for specific procedures is located
at appropriate places in this manual.

Agilent Technologies power supplies are identified by a unique two-part serial number, such as 3023A-06181. The first part
is the prefix, which denotes the date of the last significant design change and the country of manufacture. Adding 1960 to
the first two digits gives the year of the change (30 = 1990, 31 = 1991, etc.) and the second two digits identify the week of
that year. The letter indicates the country of manufacture (A = U.S.A.). The second part of the serial number consists of a 5digit number sequentially assigned to each power supply.
General Information

The serial number prefixes listed on the front of this manual indicate the versions of the supplies that were available when
the manual was issued. If the serial prefix of your supply is not listed in this manual, the manual may include a yellow
"Manual Change’’ sheet. That sheet updates this manual by defining any differences b etween the version of your supply and
the versions included here, and may also include information for correcting any manual errors. Note that because not all
changes to the product require changes to the manual, there may be no update information required for your version of the
supply.
GP-IB Interconnection Cables and Connectors
Cables for interconnecting GP-IB devices are available in four different lengths. The connector block at both ends of each
GP-IB cable has a plug on one side and a matching receptacle on the other, so that several cables may be connected in
parallel, thus simplifying system interconnection. Lock screws provide secure mounting of each connector block to a GP-IB
instrument, or to another cable connector block.

Agilent 10834A GP-IB Connector Extender
Agilent 5080-2148 Serial Link Cable, 2 m (6.6 ft)
The Agilent 10834A extender was designed to help in cases where rear panel space results in difficult cabling situations.
The extender provides clearance by extending the first connector block 2.3 cm away from the rear panel of the instrument.
Serial link cables may be used to connect power supplies together when programming with SCPI. With serial link cables,
you can connect up to 15 additional power supplies per GP-IB address. See Appendix C for more information

Installation
Introduction
This section contains instructions for checking and repacking the supply, bench or rack mounting, connecting the sup ply to
ac input power, and converting the supply from one line voltage to another if required. Instructions for connecting load and
GP-IB cables, and for setting the GP-IB address are given in Section III.
Note Agilent 603xA power supplies generate magnetic fields which may affect the operation of other
instruments. If your instrument is susceptible to operating magnetic fields, do not locate it in the
immediate vicinity of the Agilent 603xA power supply. Typically, at three inches from the supply, the
electromagnetic field is less than 5 gauss.
Initial Inspection
Before shipment, this supply was inspected and found to be free of mechanical and electrical defects. As soon as the supply
is unpacked, inspect for any damage that may have occurred in transit. Save all packing materials until the inspection is
completed. If damage is found, file claim with carrier immediately. The Agilent Technologies Sales and Support office
should be notified as soon as possible.
Mechanical Check
This check should confirm that there are no broken knobs or connectors, that the cabinet and panel surfaces are free of dents
and scratches, and that the meter face and rear-panel plastic covers are not scratched or cracked.
Electrical Check
Section III contains an abbreviated check which can be used quickly to place the supply into operation. Refer to the inside
front cover of the manual for Certification and Warranty statements.
Preparation For Use
In order to be put into service, the power supply must be connected to an appropriate ac input power source. Also, the line
voltage for which the supply is set must be checked. Additional steps may include line voltage conversion and rack
mounting. Do not apply power to the supply before reading Input Power Requirements paragraph on the following page.
Location and Cooling
The supply is fan cooled and must be installed with sufficient space in the rear and on sides for air flow. It should be used in
an area where the ambient temperature does not exceed + 50 °C.
Outline Diagram
Figure 2-1 illustrates the outline shape and dimensions of the cabinet.
Installation
21
Figure 2-1. Outline Diagram
Bench Operation
The supply cabinet has plastic feet, which are shaped to ensure self aligning when stacked with other Agilent Technologies
System II cabinets.
Rack Mounting
The supply can be mounted in a standard 19-inch rack enclosure. Rack mounting accessories for this unit are listed in the
ACCESSORIES paragraph in Section I. Complete installation instructions are included with each rack mounting kit.
Support rails are also required for rack mounting. These are usually supplied with the system cabinet.
Input Power Requirements
This supply may be operated from a nominal 120 V, 220 V or 240 V single-phase ac power source (48-63 Hz). The input
voltage range and input current required for each of the nominal inputs are listed in Table 1-1. A label on the rear panel
indicates the nominal line voltage for which the supply was set at the factory. If necessary, the user can convert the
instrument from one line voltage option to another by following the instructions in the Line Voltage Option Conversion
section of this chapter.
Power Connection
Connection of this supply to an ac power source should be done only by an electrician or other
qualified personnel. Before connecting the supply to the ac power source, check the label on the rear
panel to ensure that the supply is set for the ac voltage to be used. If necessary, convert the supply
from one line voltage to another by following the instructions under “Line Voltage Conversion.”
Installation
22
Agilent Models 6033A, 6031A, 6032A, 6036A. Figure 2-2 illustrates the standard configuration of power-cord plugs used by
Agilent Technologies. To connect input power, to the instrument proceed as follows:
a. Remove the AC filter assembly cover by unscrewing the four locating screws.
b. Insert the power cord through the strain relief cla mp located on the cover.
c. Connect the wires to the terminal block in accordance with the prevailing color codes.
Green or green/yellow to the terminal labeled "
White or blue wire to the terminal labeled "N’’
Black or brown wire to the terminal labeled ’’L"
For proper protection by the instrument circuit breaker, the wire connected to the "L’’ terminal on the
instrument must be connected to the "L’’ side of the line (hot); the wire connected to the ’’N" terminal
must be connected to the "N" side of the line (neutral or common).
’’
Figure 2-2. Power-Cord Plug Configurations
To protect operating personnel, the wire connected to the terminal must be connected to earth ground. In no event shall this
instrument be operated without adequate ground connection.
Installation
23
d. Replace the cover, tighten all four screws and tighten the strain relief clamp. (All four screws must be tightened for unit
to meet RFI specifications.)
e. Connect the other end of the power cord to an appropriate power source.
Note Connections to the ac power line must be made in accordance with applicable electrical codes. The
international color code for identifying mains supply conductors is green/yellow, blue, and brown for
earth, neutral, and line respectively. Corresponding USA/Canadian codes are green, white, and black.
Before applying power to the instrument, check to see that the rear-panel circuit breaker CB1 is on
(breaker may trip because of rough handling during transit). If the breaker trips while power is on, or
if the breaker is found to be tripped at any time for unknown reasons, refer to troubleshooting
procedures in the Service Manual.
Agilent Models 6033A, 6038A. The power supply is shipped from the factory with a power-cord plug appropriate for the
user’s location. Figure 2-2 illustrates the standard configuration of power-cord plugs used by Agilent Technologies. With
each drawing is the Agilent Part Number for a replacement power cord equipped with a plug of that configuration. If a
different power cord is required, contact the nearest Agilent Technologies Sales and Service office.
To protect operating personnel, the National Electrical Manufacturers Association (NEMA) recommends that the instrument
panel and cabinet be grounded. This supp ly is equippe d with a three-conductor power cable; the third conductor is the
ground conductor. When the cable is p lugged into an appropriate receptacle the supp ly is grounded. In no event shall this
supply be operated without an adequate cabinet ground connection.
The offset pin on the standard power cable three-prong connector is the ground connection. If a two-contact receptacle is
encountered, it must be replaced with a properly grounded three-contact receptacle in accordance with the National
Electrical Code, local codes and ordinances. The work should be done by a qualified electrician.
Note Generally, it is good practice to keep the ac input lines separated from signal lines.
Line Voltage Option Conversion
Conversion to or from 100 V operation requires recalibration and replacement of internal components
in addition to the line voltage components, and is to be done only at the factory. Failure to reconfigure
and recalibrate the power supply may result in damage to the unit.
Agilent Models 6030A, 6031A, 6032A, 6035A. Line voltage conversion is accomplished by adjusting three components:
a two-section line select switch, and a line-voltage jumper. To convert the supply from one line voltage option to another,
proceed as follows:
Some components and circuits are at ac line voltage even with the LINE switch off. To avoid electric
shock hazard, disconnect line cord and load, and wait two minutes before removing cover.
a. Remove the outside cover by removing the four screws that hold the carrying straps, spread the bottom of the cover
slightly and carefully slide the cover to the rear of the supply until it is clear. Next remove the top inside cover by
removing the nine screws, four on top, three on right side, and two on left side, which connect the top inside cover to
the supply chassis.
Installation
24
b. Use a small-blade screwdriver to set the two switch sections of S2 to match the pattern silk-screened on main board for
nominal line voltage to be used. For example, to set switches for 120 V operation, move forward switch section so that
its white slot is toward front of supply and move rearward switch section so that its white slot is toward rear of the
instrument.
c. Set switch S1 to match the rearward section of S2, i.e., toward the rear for 100/120 V operation, toward the front for
220/240 V operation.
d. One end of W1 is soldered to the main board; the other end has a female quick-connect terminal that fits onto one of
two terminals soldered to the main board. For 100 V or 120 V operation, W1 must be connected to terminal J9; for 220
V or 240 V operation, W1 must be connected to terminal J10. Be certain that jumper is firmly mated with connector on
main board. Do not grip jumper insulation with pliers; either grip jumper wire by hand or grip jumper terminal with
pliers.
e. Replace the inside top cover and the outside top cover. Mark the unit clearly with a tag or label indicating correct line
voltage to be used.
f. Change line label.
Agilent Models 6033A, Agilent 6038A. Line voltage conversion is accomplished via three components; a two-section line
select switch, line voltage jumper, and a rear panel fuse.
To convert the supply from one voltage to another, proceed as follows:
a. Remove the outside cover by removing the rear screw that holds the carrying strap, then carefully slide the cover to the
rear of the supply until it is clear.
b. The line voltage select switch (S2) is located in the front left corner of the supply (see Figure 2-3). Use a small-blade
screwdriver to set the two switch sections to match the pattern silk-screened on p.c. main board as shown in Figure 2-3.
For example, to set switches for 120 V operation (as illustrated), move forward switch section so that its white slot is
toward front of supply and move rearward switch section so its white slot is toward rear of supply.
c. One end of W5 is soldered to motherboard; the other end has a female right-angle quick-connect terminal that fits onto
one of two terminals soldered to motherboard. For 100 V or 120 V operation, W5 must be connected to terminal closer
to center of supply; for 220 V or 240 V operation, W5 must be connected to terminal closer to side of supply. Be
certain that jumper is firmly mated with terminal on motherboard. Do not grip jumper insulation with pliers; either grip
jumper wire by hand or grip jumper terminal with pliers.
d. Check rating of fuse installed in rear-panel fuseholder. It should be 8 A for 100 or 120 Vac line voltages, or 4 A for
220 or 240 Vac line voltages. If necessary, replace the fuse with one of correct value. Do not use time-delay fuses.

AC Line Impedance Check
The power supply is designed for proper operation with line impedance typically found in ac power lines. However, if the
supply is connected to an ac power line having high impedance combined with line voltage near the minimum specified
value, (e.g., 104 Vac for nominal 120 Vac), the unit will go out of regulation if it is asked to provide full rated output power.
Such a situation might occur if the supply is connected to ac power an extended distance from the main ac distribution
terminals and/or if the ac power wires from the main ac distribution terminals are of relatively small gauge.
Measurement of ac line voltage at the supply input terminals typically is not a reliable indication of the actual ac line voltage
because of the peak clipping effect of the power supply and the averaging effect of the voltmeter. Symptoms of excessive
line impedance may include erratic or no output from the supply and/or inability of the supply to provide full output power.
If there is reason to suspect the ac power lines to the supply may have high impedance, perform the following check:
This check should be performed only by service-trained personnel who are aware of the hazards
involved (for example, fire and electrical shock). Turn power supply off before making or breaking
connections to power supply. Hazardous voltages are present within the unit even when power switch
is turned off.
a. Connect a variable load to the supply. Using the OUTPUT ADJUST controls and DISPLAY SETTINGS, set voltage
and current (see Section III for detailed description) to maximum rating.
b. Set the load to the maximum rated output current for the power supply (see Table 1-1). The power supply output
voltage should be greater than:
65 V for Agilent 6030A 6 V for Agilent 6033A
8 V for Agilent 6031A 220 V for Agilent 6035A
22 V for Agilent 6032A 20 V for Agilent 6038A
c. If the supply voltage is less than specified, perform the power limit calibration given in the Service Manual. If the
power limit is calibrated correctly, but the unit still does not provide the required output, then the power supply is not
receiving adequate ac line input.
Repackaging For Shi pment
To insure safe shipment of the instrument, it is recommended that the package designed for the instrument be used. The
original packaging material is reusable. If it is not available, contact your local Agilent Technologies Sales and Support
office to obtain the materials. This office will also furnish the address of the nearest service office to which the instrument
can be shipped. Be sure to attach a tag to the instrument specifying the owner, model number, full serial number, and service
required or a brief description of the trouble.

OPERATING INSTRUCTIONS
Introduction
This section describes the operating controls and indicators, turn-on checkout procedures, and operating procedures and
considerations for the power supply. Local (front-panel) and remote (via GP-IB) operation are described separately, but the
user should become familiar with both methods of operation. Information in pages 1-43 of this section applies to both local
and remote operation.
Standard Commands for Programming Instruments (SCPI) programming is described in Appendix C at the rear of this
manual.
Programming examples for specific Agilent Technologies computers are given in Appendix D. More theoretical
descriptions regarding the operational features of power supplies in general are given in the DC Power Supply Handbook,
Application Note 90B (available at no charge from your local Agilent Technologies Sales Support Office).

Operating Instructions
29
Before the instrument is turned on, all protective earth terminals, extension cords, and devices
connected to the power supply should be connected to a protective earth ground. Any interruption of the
protective earth grounding will cause a potential shock hazard that could result in personal injury.
This instrument can be damaged by electrostatic discharge into the GP-IB and control connectors, or the
switches on the rear panel
connectors and switches (which may occur when they are touched) while the unit is turned on.
Also, consistent with good engineering practice, leads attached to customer accessible signal/monitoring
ports should be twisted and shielded to maintain the instruments specified performance.
while the unit is turned on. Do not cause an electrostatic discharge into these
Controls and Indicators
The front-panel controls and indicators are shown in Figure 3-1 and described in Table 3-1. Table 3-1 also lists the
paragraphs, in which, use of the controls and indicators is described.
Output Range For An Autoranging Power Supply
The power supply can operate as a constant voltage (CV) or constant current (CC) source over a wide range of output
voltage and current combinations. The specifications table contains a graph showing the overall output range of the power
supply. Figure 3-2 shows a rectangular operating loc us tha t is defined by voltage and current settings of the power supply.
The point on that locus at which the power supply actually operates is determined by the load resistance. Three loadresistance lines are shown on Figure 3-2. The line representing load resistance A, the highest load resistance shown on the
graph, crosses the operating locus at point 1. Point 1 is on the part of the operating locus defined by the voltage setting, so
the power supply operates in CV mode.
Figure 3-2. Determining Operating Point
Similarly, the line representing load resistance C, the lowest load resistance shown on the graph, crosses the operating locus
at point 3. Point 3 is on the part of the operating locus defined by the current setting, so the power supply operates in CC
mode.
