Returning Your Signal Generator for ServiceUse the information in this section if you need to return the signal generator toAgilent Technologies.

Packaging the Signal GeneratorUse the following steps to package the signal generator for shipment to AgilentTechnologies for service:

1. Fill out a blue repair tag (available at the end of this chapter) and attach it to theinstrument. Be as specific as possible about the nature of the problem. Send a copy ofany or all of the following information:

• Any error messages that appeared on the signal generator display.

• A completed performance test record from the calibration guide for your instrument.

• Any other specific data on the performance of the signal generator.

2. Use the original packaging materials or a strong shipping container that is made ofdouble-walled, corrugated cardboard with 159 kg (350 lb) bursting strength. The cartonmust be both large enough and strong enough to accommodate the signal generator andallow at least 3 to 4 inches on all sides of the signal generator for packing material.

CAUTION Signal generator damage can result from using packaging materials otherthan those specified. Never use styrene pellets, in any shape, as packagingmaterials. They do not adequately cushion the instrument or prevent it fromshifting in the carton. Styrene pellets cause equipment damage by generatingstatic electricity and by lodging in the signal generator fan.

3. Surround the instrument with at least 3 to 4 inches of packing material, or enough toprevent the instrument from moving in the carton. If packing foam is not available, thebest alternative is SD-240 Air Cap™ from Sealed Air Corporation (Hayward, CA94545). Air Cap looks like a plastic sheet covered with 1-1/4 inch air-filled bubbles. Usethe pink Air Cap to reduce static electricity. Wrap the instrument several times in thematerial to both protect the instrument and prevent it from moving in the carton.

4. Seal the shipping container securely with strong, nylon adhesive tape.

5. Mark the shipping container “FRAGILE, HANDLE WITH CARE” to ensure carefulhandling.

6. Retain copies of all shipping papers.

Initial Troubleshooting and RF Block Diagrams ESG Family Signal GeneratorsInitial Troubleshooting

Initial TroubleshootingPerform the following troubleshooting steps in the order they are presented. If you areunable to identify the failed assembly, go to Chapter 2, “Assembly-Level Troubleshootingwith Block Diagrams,” for further instruction.

NOTE Do not attempt to replace any fuses within the power supply to correct aproblem with your signal generator. If you determine that the power supply isthe failed assembly, replace the power supply.

Step 1: Observe the Front and Rear Panel LEDsObserving the LEDs on the front and rear panel of the signal generator will determine ifthere is a catastrophic failure in the power supply assembly.

1. Ensure the signal generator is plugged in (do not switch the power on) and verify thatthe yellow LED on both the front and rear panels is lit. Refer to Figure 1-1 for LEDlocations. A lit yellow LED (+15 V_STBY) indicates that line voltage is present.

2. Power on the signal generator and verify that the green LED on both the front and rearpanels is lit. A lit green LED indicates the power supply has received an “ON”command. The ON/OFF switch toggles a flip-flop latch which biases the propertransistors in the LED control circuit. This circuit is powered by VBAT, thebattery-backed SRAM supply, so that the on-off state is “remembered” even when theinstrument is unplugged.

Figure 1-1 LED Locations on the Front and Rear Panels

1-12 Service Guide

ESG Family Signal Generators Initial Troubleshooting and RF Block DiagramsInitial Troubleshooting

Step 2: Power On the Signal Generator and Check for ErrorMessagesThis procedure verifies that the signal generator powers up and that the internalinstrument check identifies no errors. The internal check evaluates the correctness ofoperation and returns an error message if a problem is detected.

1. Switch on the signal generator. Let the signal generator warm up for at least fiveminutes.

NOTE For ESG-AP, ESG-DP, and Option 1E5 signal generators, ERROR 514,Reference Oven Cold will occur whenever the signal generator is poweredup within five minutes of being connected to AC line power. The OVEN COLDannunciator and the ERR annunciator will both turn on. The OVEN COLDannunciator will automatically clear after approximately five minutes. Theerror queue cannot be cleared, however, until the OVEN COLDannunciator hasturned off.

2. Cycle the power to the signal generator and verify that the green LED on both the frontand rear panels is lit. Refer to Figure 1-1.

3. When the display is lit, check to see if the ERR annunciator is turned on.

4. If the ERRannunciator is turned on, review the error messages in the queue by pressingUtility > Error Info > View Next Error Message . The first error message in the queue will beshown in the text area of the display. Refer to the Error Messages guide for descriptionsof error messages.

If there is more than one error message (each message will be designated as 1 of n),continue pressing the View Next Error Message softkey until you have seen and recorded allof the messages.

5. If you were able to resolve all of the error messages, press Utility > Error Info >Clear Error Queue(s) to delete the list of error messages.

Service Guide 1-13


Step 3: Functional Check the Front Panel Keys and Display

1. Press various front panel hardkeys and softkeys to verify they function as expected.

2. Use the contrast keys to verify that the display can be lightened and darkened. Refer toFigure 1-2.

1-14 Service Guide


Step 4: Visually Check the Individual Voltage Supplies

1. Unplug the signal generator and remove the instrument cover. Refer to Chapter 5,“Assembly Replacement,” for removal instructions.

2. Expose the motherboard by removing the top cover. It is secured by 11 screws.

3. Plug in the signal generator and allow it to warm up for at least five minutes.

4. If possible, clear the error queue(s) of messages. Press Utility > Error Info > Clear ErrorQueue(s) .

5. On the motherboard, locate the 10 LEDs that correspond to the individual voltagesupplies (see Figure 1-3). Verify that all the LEDs are lit. If one or more LEDs are off,proceed to “Step 6: Isolate the Failed Assembly”.

Figure 1-3 LED Locations on the Motherboard

Service Guide 1-15


Step 5: Measure the Individual Voltage SuppliesThe voltages supplied as inputs from the power supply via J6 to the motherboard are+15 V (TP502), +15 V standby (+15 V_STBY), −15 V (TP503), +12 V (TP505), and+5.2 V (TP302). DGND (TP301) is associated with these supplies.

The −6 V (TP508) and −5.2 V (TP509) supplies receive their input from the +5.2 V digitalsupply (5.2 VD at TP506). The +5.2 V digital line is filtered to prevent the switching powersupply noise from being induced onto the +5.2 VD supply lines. The −6 V is a bias voltagefor circuits on the output board and other RF circuitry. The −5.2 V is used by the emittercoupled logic (ECL) digital ICs. The LCD display driver voltage (VLCD), a −14 V to −24 Vsource, also receives input from the +5.2 VD supply.

The input to the +32 V supply (TP504) is the +12 V supply. The +32 V supply is used by thesynthesizer/doubler assembly. This supply also includes an LC noise filter.

The +12.5 V regulated supply (TP510) originates from the +15 V input. The −12.5 Vregulated supply (TP511) originates from the −15 V input. These two supplies are used bythe solid-state attenuator and the reverse power protection (RPP). The +10 V reference(TP501) originates from the +15 V input. The +9 V supply (TP507) originates from the+10 V reference and the +12 V supply.

1. Unplug the signal generator and turn it upside-down.

2. Expose the motherboard by removing the bottom cover. It is secured by 15 screws.

3. Plug in the signal generator.

4. Measure the voltage of each supply to verify they are within the tolerances listed inTable 1-3. The voltage supply test point locations are shown in Figure 1-4. If all thevoltages are within tolerance, proceed to “Step 7: Check for Basic CPU Functionality”.

NOTE Refer to Chapter 4, “Replaceable Parts (ESG-AP and ESG-DP Series),” forinformation on locating assemblies. Refer to Chapter 5, “AssemblyReplacement,” for information on removing or disconnecting assemblies.

3. Switch on the signal generator and check the voltage supply LEDs (see Figure 1-3). Ifthe LEDs are lit, you have likely identified the failed assembly. If one or more LEDs arestill off, switch off the signal generator and replace/reconnect the assembly and repeatthis procedure.

1-20 Service Guide


Step 7: Check for Basic CPU FunctionalityThe Digital Signal Processor (DSP) performs a self-diagnostic test at power up. If the DSPis not working, the CPU reports an error.

If the DSP does not seem to be working and the CPU did not report the error, then checkthe CLK_OUT signal at TP701. It should be a 16 MHz signal. (Refer to Figure 1-5.)

The eight LEDs of DS201 (see Figure 1-5) indicate the status of the boot and flash ROM forthe CPU. The LEDs form a binary code that can be described as a two digit hexadecimalcode. Table 1-4 shows the test sequence and the LED pattern (binary representation) of thetest that is running. If an error occurs and the test is halted, the LED pattern will indicatewhich self test halted the process. The LED closest to R201 is the place holder for the LeastSignificant Bit (LSB) in the pattern.

ESG Family Signal Generators Initial Troubleshooting and RF Block DiagramsAdditional Information for Troubleshooting the ESG-AP and ESG-DP Series

Additional Information for Troubleshooting theESG-AP and ESG-DP SeriesTable 1-5 provides frequency-dependent settings for selected points in the RF signal flow ofthe ESG-AP and ESG-DP Series Signal Generators. Notice that the settings are relative tothe RF output frequency. This information can improve your understanding of the signalgenerator circuitry, especially when used with the RF block diagram.

NOTE The values for Table 1-5 assume FM modulation is turned off.

2 Assembly-Level Troubleshooting withBlock Diagrams

This chapter provides the block diagrams and information necessary for you to test andtroubleshoot the major assemblies of your signal generator.

Service Guide 2-1

Assembly-Level Troubleshooting with Block Diagrams ESG Family Signal GeneratorsBefore You Begin Troubleshooting

Before You Begin TroubleshootingBe sure to review the warning and caution statements described in Chapter 7 prior totroubleshooting your signal generator.

Using this Chapter with Service SoftwareSome block diagrams in this chapter are accompanied by a table for use with theautomated service software that came with your signal generator. These tables list thesignal generator’s test conditions and the expected ABUS node voltages. The servicesoftware has a utility program which measures and displays the node voltages for eachtest. Refer to your signal generator’s calibration guide for information on using thesoftware.

The block diagrams and ABUS node tables are arranged in the following order:

ESG Family Signal Generators Replaceable Parts (ESG-A and ESG-D Series)Save Money with Rebuilt-Exchange Assemblies

Save Money with Rebuilt-Exchange AssembliesUnder the rebuilt-exchange assembly program, certain factory-repaired and tested assemblies are available on a trade-in basis. These assemblies cost less than a new assembly, and meet all factory specifications required of a new assembly.

The defective assembly must be returned for credit under the terms of the rebuilt-exchange assembly program. The figure below illustrates the assembly exchange procedure in flowchart format.

Assembly Exchange Procedure

Service Guide 3-3

Replaceable Parts (ESG-A and ESG-D Series) ESG Family Signal GeneratorsSave Money with Rebuilt-Exchange Assemblies

Shipping the Defective Assembly Back to Agilent Technologies

1. When you receive the rebuilt assembly, be careful not to damage the box in which it was shipped. You will use that box to return the defective assembly. The box you receive should contain the following:

• the rebuilt assembly

• an exchange assembly failure report

• a return address label

2. Complete the failure report.

3. Place the failure report and the defective assembly in the box. Be sure to remove the enclosed return address label.

4. Seal the box with tape.

If you are inside the United States, stick the preprinted return address label over the label that is already on the box and return the box to Agilent Technologies. (Agilent Technologies pays postage on boxes mailed within the United States.)

If you are outside the USA, do not use the return address label; instead, address the box to the nearest Agilent Technologies sales and service office. (Refer to Table 1-1 on page 1-9.)

ESG Family Signal Generators Replaceable Parts (ESG-AP and ESG-DP Series)Save Money with Rebuilt-Exchange Assemblies

Save Money with Rebuilt-Exchange AssembliesUnder the rebuilt-exchange assembly program, certain factory-repaired and tested assemblies are available on a trade-in basis. These assemblies cost less than a new assembly, and meet all factory specifications required of a new assembly.

The defective assembly must be returned for credit under the terms of the rebuilt-exchange assembly program. The figure below illustrates the assembly exchange procedure in flowchart format.

Assembly Exchange Procedure

Service Guide 4-3

Replaceable Parts (ESG-AP and ESG-DP Series) ESG Family Signal GeneratorsSave Money with Rebuilt-Exchange Assemblies

Shipping the Defective Assembly Back to Agilent Technologies

1. When you receive the rebuilt assembly, be careful not to damage the box in which it was shipped. You will use that box to return the defective assembly. The box you receive should contain the following:

• the rebuilt assembly

• an exchange assembly failure report

• a return address label

2. Complete the failure report.

3. Place the failure report and the defective assembly in the box. Be sure to remove the enclosed return address label.

4. Seal the box with tape.

If you are inside the United States, stick the preprinted return address label over the label that is already on the box and return the box to Agilent Technologies. (Agilent Technologies pays postage on boxes mailed within the United States.)

If you are outside the USA, do not use the return address label; instead, address the box to the nearest Agilent Technologies sales and service office. (Refer to Table 1-1 on page 1-9.)

ESG Family Signal Generators Assembly ReplacementSemi-Rigid Cables

Semi-Rigid CablesUse this procedure to remove and replace semi-rigid cables that attach to thedaughterboard card cage. If the cable you are removing/replacing does not attach to thedaughterboard card cage, no special instruction is necessary other than step 3 in the“Replacement” section below.

Tools Required

• MILBAR 2R snap-ring pliers (used to remove snap rings from cable retainers)


Removal

1. Remove all the daughterboard card cage boards to allow access to the instrumentchassis cable connections. (Refer to the “Daughterboard Card Cage Boards”replacement procedure on page 5-56.)

2. Remove the snap ring (item 1 in Figure 5-44) from the cable retainer (item 2) of thecable you want to remove. The cable is now disconnected from the instrument chassis(item 3).

3. Disconnect the other end of the cable.

Replacement

1. If you’re installing a new cable, a new cable retainer (item 2) must first be attached tothe end of the cable (item 4). Verify the cable retainer is correctly attached by listeningfor an audible “click” as you slide it over the end of the cable.

2. Insert the cable-retainer end of the cable assembly into the opening of the instrumentchassis and then secure it with a snap ring.

3. Connect the other end of the cable. All semi-rigid cables should be torqued to 9 in-lbs.

4. Replace the daughterboard card cage boards.
