ESD Information Protection from Electrostatic Discharge Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic assemblies should be performed at a static-safe workstation. Figure 1-1 shows an example of a static-safe workstation using two types of ESD protection: o o Conductive table-mat and wrist-strap combination. Conductive floor-mat and heel-strap combination. Chapter 1 15 16 Troubleshooting the Analyzer Before You Start Both types, when used together, provide a significant level of ESD protection. Of the two, only the table-mat and wrist-strap combination provides adequate ESD protection when used alone. To ensure user safety, the static-safe accessories must provide at least 1 megohm of isolation from ground. Refer to Table 1-1 on page 16 for information on ordering static-safe accessories. WARNING Figure 1-1 These techniques for a static-safe workstation should not be used when working on circuitry with a voltage potential greater than 500 volts. The risk of ESD damage can be greatly reduced by close attention to how all components are handled.Keep static-generating materials at least one meter away from all components. Store or transport components in static-shielding containers. CAUTION Always handle printed circuit board assemblies by the edges. This will reduce the possibility of ESD damage to components and prevent contamination of exposed plating. Test Equipment Usage and ESD o o o Before connecting any coaxial cable to an analyzer connector, momentarily short the center and outer conductors of the cable together. Personnel should be grounded with a 1 megohm resistor-isolated wrist-strap before touching the center pin of any connector and before removing any assembly from the analyzer. Be sure that all analyzers are properly earth-grounded to prevent build-up of static charge. The ESD standards developed by this agency are sanctioned by the American National Standards Institute (ANSI).
18 Chapter 1 19 Troubleshooting the Analyzer Check the Basics Check the Basics A problem can often be resolved by repeating the procedure you were following when the problem occurred. Before calling Agilent Technologies or returning the analyzer for service, please make the following checks: o o o o o o o Check the line fuse. Is there power at the receptacle. Is the analyzer turned on. Make sure the fan is running, which indicates that the power supply is on. If the display is dark or dim, press the upper Viewing Angle key in the upper-left corner of the front panel. If the display is too bright, adjust the lower Viewing Angle key in the upper-left corner of the front panel. If other equipment, cables, and connectors are being used with your analyzer, make sure they are connected properly and operating correctly. Review the procedure for the measurement being performed when the problem appeared. Are all the settings correct. If the analyzer is not functioning as expected, return the analyzer to a known state by pressing the Preset key and Factory Preset (if present). Some analyzer settings are not affected by a Preset. Refer to the Front-Panel Key Reference chapter of the user s guide for information on settings affected by a Preset.Refer to the appropriate Specifications and Characteristics chapters in the specifications guide for more details. In order to meet specifications, the analyzer must be aligned. Either Auto Align All must be selected (press System, Alignments, Auto Align, All), or the analyzer must be manually aligned at least once per hour, or whenever the temperature changes more than 3 C. When Auto Align, All is selected, AA appears on the left edge of the display. Refer to the appropriate Specifications and Characteristics chapters in the specifications guide for more details. Is the analyzer displaying an error message.
If the necessary test equipment is available, perform the performance verification tests in the calibration guide or use the performance verification software. Record all results on a Performance Verification Test Record form which follows the tests. If the equipment to perform the performance verification tests is not available, you may still be able to perform the functional checks in the user s guide. Chapter 1 19 20 Troubleshooting the Analyzer Problems at Instrument Power-Up Problems at Instrument Power-Up This section describes symptoms that can occur when the analyzer is first powered on. CAUTION Immediately unplug the analyzer from the ac power line if the unit shows any of the following symptoms: Smoke, arcing, or unusual noise from inside the unit, except as noted below. No response of any kind when unit is plugged into ac power mains and turned on. The analyzer ac power fuse blows. A circuit breaker or fuse on the main ac power line opens. These potentially serious faults must be corrected before proceeding. Refer to Troubleshooting an Inoperative Analyzer on page 21. Note that these analyzers are equipped with a speaker and normally emit noise from the speaker at power-up. This is not a problem; adjust the volume control as desired. The analyzer will also occasionally emit clicking noises. These are normal and are related to the analyzer self alignment routines. If the analyzer always turns on when power is applied, check the rear of the analyzer. There is an always on power mode switch that can be changed. Refer to the rear panel features section of the user s guide for information on this switch. 20 Chapter 1 21 Troubleshooting the Analyzer Troubleshooting an Inoperative Analyzer Troubleshooting an Inoperative Analyzer When an analyzer appears to be dead (no display or inoperative fan) there is often little evidence that points directly to the cause. This section provides steps and solutions to typical failure modes relating to an inoperative analyzer.
Before troubleshooting an analyzer, ensure that it has been set up correctly. Check the Analyzer Setup Perform the steps in the section titled Check the Basics earlier in this chapter. Initial Checks Perform the following initial checks when first troubleshooting an inoperative analyzer. 1. Is the fan running? a. If the fan is not running, refer to the section If the Fan is Not Operating on page 22. b. If the fan is running, this indicates the power supply is functioning at least partially. 2. Is the display on? a. If the display is blank, refer to the section Checking the Power Supplies on page 23. Also verify that the firmware is good by performing the Bootrom Self-Test Check on page 38. b. If the display is on and the fan is running, suspect one or more power supplies is being pulled down, or a defective processor assembly. In either case, the analyzer outer case and inner shield must be removed. Refer to Chapter 6 for removal procedures. 3. Check the power supplies. a. To check the power supply voltages, refer to the section Checking the Power Supplies on page 23. b. If the supplies all measure good, suspect a defective processor, or a defective LCD or interface board. Chapter 1 21 22 Troubleshooting the Analyzer Troubleshooting an Inoperative Analyzer 4. Perform the following checks for the processor assembly. a. Is the analyzer clicking. The analyzer should occasionally emit clicking noises. These are related to the analyzer automatic self alignment routines, and indicate the processor is basically functioning. When the analyzer is cold, there will be more self alignment activity (more clicking) than when it is warm. If you do not hear any clicks after a few minutes, suspect a defective processor assembly. Refer to the section Troubleshooting the A4 Processor Assembly on page 37. b. Are the processor assembly LEDs all out. There are LEDs along the top edge of the processor assembly. These should all be off.
To check their functionality, cycle the analyzer power. The processor LEDs should all go on for a few seconds, then go off. If one or more LEDs remains on, suspect the processor assembly is defective. Refer to the section Bootrom Self-Test Check on page 38. c. If the analyzer is clicking, and all of the processor LEDs are out, suspect a defective LCD or a defective front panel interface board. Refer to the section Troubleshooting the LCD Display on page 25. If the Line Fuse Has Blown If the line fuse has blown, perhaps a nonstandard fuse with too low a current rating was installed. If the line fuse still blows, suspect that the power supply assembly is defective. If the Fan is Not Operating CAUTION The power supply may be hot if the instrument has been operating without the fan running. Allow the instrument to cool down before troubleshooting. 1. If there is no display: a. Unplug the line-power cord. b. Change the switch at the rear of the analyzer so the power is always on. Refer to the rear panel features section of the user s guide for information on this switch. This will bypass the front panel power switch. 22 Chapter 1 23 Troubleshooting the Analyzer Troubleshooting an Inoperative Analyzer c. If the fan still does not turn on, suspect a defective power supply assembly. Refer to the section Checking the Power Supplies on page 23, to check individual supply voltages. d. If the fan starts, this indicates a problem with the front panel switch or the circuitry to the front panel switch. 2. If there is a display: a. Remove the analyzer outer case. Refer to Chapter 6 for removal details. b. Measure the fan voltage. c. The fan voltage can be checked directly at the center of the fan where the wires connect. The fan normally operates on a voltage ranging from 5 to 16 Vdc depending on the temperature of the analyzer. As analyzer temperature increases, fan voltage should become more negative, increasing the speed of the fan.
If the correct voltage is present, suspect a defective fan. If the voltage is not present, check the plug where the fan wires attach to the power supply board. If this looks good, suspect a defective power supply. Refer to Chapter 6 for information on how to remove the power supply. Checking the Power Supplies The power supply test board is no longer supplied. If the power supply is suspect, change the power supply. All ESA models use the same power supply, so substitution is possible to determine if the power supply is defective. WARNING The analyzer contains potentially hazardous voltages. Refer to the safety symbols provided on the analyzer, and in the general safety instructions in this guide, before operating the unit with the cover removed. Ensure that safety instructions are strictly followed. Failure to do so can result in severe or fatal injury. See Figure 1-2 for these test points. If 12.6 V is within limits, it is a reasonably good indicator that 15 V is within specifications. Chapter 1 23 24 Troubleshooting the Analyzer Troubleshooting an Inoperative Analyzer Figure 1-2 Probe Power Connector Voltages If All Low Voltage Supplies are At or Near Zero Volts If all the power supplies are dead, suspect a defective A5 power supply assembly. Refer to Chapter 6 for removal instructions. If Some Low Voltage Supplies are At or Near Zero Volts If some supplies are functioning while others are dead or low, it is possible that one of the assemblies in the analyzer is loading down the power supply. In this case it is necessary to sequentially remove the assemblies, taking care to disconnect the line-power cord before removing any assembly. A logical first step would be to unplug the RF assembly ribbon cable from the motherboard at the rear of the instrument. This disconnects the complete RF section without having to remove it from the chassis. Refer to Chapter 6 for any other assembly removal procedures.
After an assembly is disconnected or removed, plug the line-power cord back into the analyzer and remeasure the supply that was down. If it is still down, continue with the assembly removal. If the supply is now up, suspect the last assembly removed as being defective. 24 Chapter 1 25 Troubleshooting the Analyzer Troubleshooting the LCD Display Troubleshooting the LCD Display The only adjustment that can be made to the LCD display is the viewing angle. This is found on the front panel of the analyzer in the upper left corner. Viewing Angle 1. Verify that the analyzer has gone through a full power-on sequence. Refer to the section Troubleshooting an Inoperative Analyzer on page If the display is dark (not visible), connect an external VGA monitor to the rear panel VGA output connector on the analyzer. It is possible that some multisync monitors may not be able to lock to a 60 Hz sync pulse. If the video information is not present on the external VGA monitor, the most probable cause is the A4 processor assembly. 3. If the external VGA monitor is functioning, verify that the ribbon cables going to and from the A1A1 front panel interface assembly are aligned properly and securely plugged into the connectors. 4. To determine whether the A1A2 LCD display or the A1A1 front panel interface assembly is defective, remove the front frame assembly. WARNING Table 1-2 The inverter board contains high voltage for the backlights. Carefully remove the inverter board by taking out the two screws securing it to the front frame, then turn it over to access the CN1 connector. Refer to Table 1-2 on page 25 and carefully measure the voltage coming into the inverter board at CN1 pins 1-6 with a digital voltmeter. Measurement Locations and Expected Voltages Measurement Location CN1 Pin 1 CN1 Pin 2 CN1 Pin 3 CN1 Pin 4 CN1 Pin 5 CN1 Pin 6 Expected Voltage from A1A1 Front Panel Interface 0 Vdc 0 Vdc 5 Vdc 5 Vdc 30 mv 2.
5 Vdc The display is not field-repairable, and must be replaced as an assembly. Refer to Chapter 5 for part-number information. Chapter 1 25 26 Troubleshooting the Analyzer Troubleshooting the LCD Display Figure 1-3 LCD Troubleshooting Measurement Locations If the voltages are correct, the most probable cause of failure is the A1A2 LCD assembly. NOTE The LCD has two backlights to illuminate the LCD. If both backlights are defective, the screen will be dark. The backlights can be replaced individually, however, it is improbable that both backlights are defective simultaneously. If one backlight is defective, the LCD will illuminate but the dimness will be noticeable, and you will need to replace A1A2DS1 or A1A2DS2. It is recommended that both backlights be replaced at the same time if it is likely that one simply wore out. 26 Chapter 1 27 Troubleshooting the Analyzer Isolating an LO, IF, or Video Problem Isolating an LO, IF, or Video Problem This section provides techniques for isolating amplitude failures along the signal path. Checking Detector Modes The instrument has three detector modes known as peak, negative peak, and sample. All of these detectors are located on the A4 processor board. Normal instrument power up routes the detected video signal through the positive peak detector only. If there are no graticules, signal information, or screen annotations, refer to the section Troubleshooting the LCD Display on page 25. The 2 Vdc can be measured on the motherboard at A7J13 pin 24 if the analyzer is an E4403B, E4408B, or E4411B. If you do not measure a dc level at approximately 2 Vdc, the IF assembly is the most probable cause. Refer to Figure If you measure 2 Vdc on the output of the IF assembly but do not see a flat line at the top of the graticule, there may be a problem between the output of the IF assembly and the input to the A4 processor board.
Refer to section Using the Internal Service-Diagnostic Routines on page 32 for more information about the video shift function. 3. If the power hole or power spike does not go away after re-adjusting the frequency response (flatness), the RF assembly is the most probable cause. If the analyzer is in full span and the 21.4 MHz input frequency has a power level of 20 dbm, the displayed response will be the inverse of the RF assembly flatness. In narrow spans, the flatness correction will be done by changing the A3 IF assembly gain. In large spans, when it is not practical to change the A3 IF assembly gain as the analyzer sweeps, video shift is used for flatness correction. Otherwise: 1. Perform Align Now All by pressing System, Alignments, Align Now, All and wait for the alignment to complete. Three complete alignment sequences will be performed. 2. Turn Auto Align back on by pressing System, Alignments, Auto Align, All. 3. Verify the analyzer performance now that the A3 IF assembly has had the defaults loaded and the auto align has been turned back on. 28 Chapter 1 29 Troubleshooting the Analyzer Isolating an LO, IF, or Video Problem 4. If the signal on screen is still not correct perform Checking Detector Modes on page 27. Now inject a 21.4 MHz signal at 10 dbm from a synthesizer into the A3 IF assembly. With the reference level at 0 dbm, the input attenuator set to 0 db, and center frequency at 50 MHz in zero span, a flat line should appear at the top graticule. 5. If the signal is not at the top graticule, measure A7J13 pin 24 on the motherboard with a voltmeter and verify 2 Vdc. Refer to Figure If 2 Vdc is present the most probable cause is either an A7 motherboard trace problem to the A4 processor board, a bent pin on A7J7 motherboard connector, or the A4 processor board itself. Checking a Horizontal Trace With No Signal or Noise Floor Present 1. For E4402B, E4404B, E4405B, and E4407B connect the Amptd Ref out to the Input.
