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 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.

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 AgilentTechnologies Sales and Service Office for service and repair to ensure that safety features are maintained.

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.

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 60504B/60507B Modules. 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 US37240101. 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 a Agilent 60504B/60507B Electronic Load Modules. 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 set 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, CS2 appears on the schematic as CS2*.

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.

Example: CC_PROG

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:

Common +5V

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.
