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 under "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 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 (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 protection (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.

Instrument and Manual Identification

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 5- digit number sequentially assigned to each power supply.

General Information 13

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 between 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.

Model

Agilent 10833A GP-IB Cable, 1 m (3.3 ft.)

Agilent 10833B GP-IB Cable, 2 m (6.6 ft.)

Agilent 10833C GP-IB Cable, 4 m (13.2 ft.)

Agilent 10833D GP-IB Cable, 0.5 m (1.6 ft.)

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

GP-IB Compatibility

The system power supplies implement the following GP-IB interface functions:

SH1(Source Handshake)	RL1(Remote Local)
AH1(Acceptor Handshake)	PP1(Parallel Poll)
T6(Talker)	DC1(Device Clear)
L4(Listener)	DT1(Device Trigger)
SR1(Service Request)

Ordering Additional Manuals

One Operating manual is shipped with each power supply. Additional manuals may be purchased directly from your local Agilent Technologies Sales office. Specify the model number, serial number prefix, and the manual part number provided on the title page. (When ordered at the same time as the power supply, additional manuals may be purchased by adding Option 910 to the order. Each Option 910 includes one Operating and one Service Manual).

Installation

Introduction

This section contains instructions for checking and repacking the supply, bench or rack mounting, connecting the supply 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.”

22 Installation

Agilent Technologies 6035A, 6033A, 6028A, 6023A, 603xA User Manual

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 clamp 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 supply is equipped with a three-conductor power cable; the third conductor is the ground conductor. When the cable is plugged into an appropriate receptacle the supply 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.

24 Installation

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.

8 AM fuse, Agilent part number 2110-0383

4 AM fuse, Agilent part number 2110-0055

e.Replace covers and mark the supply clearly with a tag or label indicated correct line voltage and fuse to be used.

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 Shipment

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 while the unit is turned on. Do not cause an electrostatic discharge into these 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.

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 locus that 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.
