Returning Your Signal Generator for Service Use the information in this section if you need to return the signal generator to Agilent Technologies.
Packaging the Signal Generator Use the following steps to package the signal generator for shipment to Agilent Technologies for service: 1. Fill out a blue repair tag (available at the end of this chapter) and attach it to the instrument. Be as specific as possible about the nature of the problem. Send a copy of any 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 of double-walled, corrugated cardboard with 159 kg (350 lb) bursting strength. The carton must be both large enough and strong enough to accommodate the signal generator and allow 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 other than those specified. Never use styrene pellets, in any shape, as packaging materials. They do not adequately cushion the instrument or prevent it from shifting in the carton. Styrene pellets cause equipment damage by generating static 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 to prevent the instrument from moving in the carton. If packing foam is not available, the best alternative is SD-240 Air Cap™ from Sealed Air Corporation (Hayward, CA 94545). Air Cap looks like a plastic sheet covered with 1-1/4 inch air-filled bubbles. Use the pink Air Cap to reduce static electricity. Wrap the instrument several times in the material 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 careful handling. 6. Retain copies of all shipping papers.

Initial Troubleshooting and RF Block Diagrams Initial Troubleshooting
ESG Family Signal Generators
Initial Troubleshooting Perform the following troubleshooting steps in the order they are presented. If you are unable to identify the failed assembly, go to Chapter 2, “Assembly-Level Troubleshooting with Block Diagrams,” for further instruction. NOTE
Do not attempt to replace any fuses within the power supply to correct a problem with your signal generator. If you determine that the power supply is the failed assembly, replace the power supply.
Step 1: Observe the Front and Rear Panel LEDs Observing the LEDs on the front and rear panel of the signal generator will determine if there 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 that the yellow LED on both the front and rear panels is lit. Refer to Figure 1-1 for LED locations. 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 rear panels 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 proper transistors in the LED control circuit. This circuit is powered by VBAT, the battery-backed SRAM supply, so that the on-off state is “remembered” even when the instrument is unplugged. Figure 1-1 LED Locations on the Front and Rear Panels

Step 2: Power On the Signal Generator and Check for Error Messages This procedure verifies that the signal generator powers up and that the internal instrument check identifies no errors. The internal check evaluates the correctness of operation 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 five minutes. NOTE
For ESG-AP, ESG-DP, and Option 1E5 signal generators, ERROR 514, Reference Oven Cold will occur whenever the signal generator is powered up within five minutes of being connected to AC line power. The OVEN COLD annunciator and the ERR annunciator will both turn on. The OVEN COLD annunciator will automatically clear after approximately five minutes. The error queue cannot be cleared, however, until the OVEN COLD annunciator has turned off.
2. Cycle the power to the signal generator and verify that the green LED on both the front and 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 ERR annunciator is turned on, review the error messages in the queue by pressing Utility > Error Info > View Next Error Message. The first error message in the queue will be shown in the text area of the display. Refer to the Error Messages guide for descriptions of 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 all of 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.

Step 5: Measure the Individual Voltage Supplies The 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 digital supply (5.2 VD at TP506). The +5.2 V digital line is filtered to prevent the switching power supply noise from being induced onto the +5.2 VD supply lines. The −6 V is a bias voltage for circuits on the output board and other RF circuitry. The −5.2 V is used by the emitter coupled logic (ECL) digital ICs. The LCD display driver voltage (VLCD), a −14 V to −24 V source, 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 the synthesizer/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 V regulated supply (TP511) originates from the −15 V input. These two supplies are used by the 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 in Table 1-3. The voltage supply test point locations are shown in Figure 1-4. If all the voltages are within tolerance, proceed to “Step 7: Check for Basic CPU Functionality”.

Step 7: Check for Basic CPU Functionality The Digital Signal Processor (DSP) performs a self-diagnostic test at power up. If the DSP is 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 check the 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 for the CPU. The LEDs form a binary code that can be described as a two digit hexadecimal code. Table 1-4 shows the test sequence and the LED pattern (binary representation) of the test that is running. If an error occurs and the test is halted, the LED pattern will indicate which self test halted the process. The LED closest to R201 is the place holder for the Least Significant Bit (LSB) in the pattern. Table 1-4 Sequence for DSP Self-Diagnostic Tests

Initial Troubleshooting and RF Block Diagrams Additional Information for Troubleshooting the ESG-AP and ESG-DP Series
Additional Information for Troubleshooting the ESG-AP and ESG-DP Series Table 1-5 provides frequency-dependent settings for selected points in the RF signal flow of the ESG-AP and ESG-DP Series Signal Generators. Notice that the settings are relative to the RF output frequency. This information can improve your understanding of the signal generator circuitry, especially when used with the RF block diagram. The values for Table 1-5 assume FM modulation is turned off.

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.

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.)

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.)

Assembly Replacement Semi-Rigid Cables
Semi-Rigid Cables Use this procedure to remove and replace semi-rigid cables that attach to the daughterboard card cage. If the cable you are removing/replacing does not attach to the daughterboard 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) • 5/16-inch open-end wrench
Removal 1. Remove all the daughterboard card cage boards to allow access to the instrument chassis 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 the cable 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 to the end of the cable (item 4). Verify the cable retainer is correctly attached by listening for 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 instrument chassis 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. Figure 5-44 Semi-Rigid Cables
