Troubleshooting To Troubleshoot the Instrument

To Troubleshoot the Instrument

This section describes basic procedural flow of troubleshooting when servicing the E5061B. The primary procedural tool in this section is the flowchart. The flowchart contains entire troubleshooting path from a failure symptom to the isolation of faulty assembly, and will direct you to the completion of repair in an ordinary manner through the possible failure symptoms. Reference letters (Yes/No) on the flowcharts point to procedural steps that briefly explain the troubleshooting method to be performed next.

Primary Trouble Isolation

The primary trouble isolation procedure can be performed without disassembling the E5061B. Figure 2-2 shows the trouble isolation flow chart.

Step 1. Turn the instrument power on

About a few minutes after the E5061B is turned on, the measurement view is displayed on the screen. The display on the screen should be similar to Figure

2-12, “Measurement view,” on page 31.

Step 2. Check the display

• If no display appears on the LCD after the E5061B is turned on, go to “No

Display Troubleshooting” on page 23.

• If the E5061B stops in booting process despite something being displayed

on the LCD, go to “Booting Process Troubleshooting” on page 27.

• The power-on self test is performed once automatically after the E5061B measurement view is displayed. If the power-on self test fails, go to

“Troubleshooting Using Diagnostic Test” on page 32.

Step 3. Check the basic function

If the front-panel/keyboard/mouse controls, LCD display, data storage, remote interface or another function (except for measurement part) does not work correctly, go to

“Function Specific Troubleshooting” on page 39.

Step 4. Check the measurement function

If the instrument fails performance tests, go to

Troubleshooting” on page 46

If the measurement function does not work correctly, perform the diagnostic test provided in the E5061B's service function. When the diagnostic test fails, go to “Diagnostic Test Failure Troubleshooting” on page 36.

“Performance Test failure

The diagnostic test includes some unique measurement function tests in addition to the tests that are common to the power-on self test. Thus, it is necessary to perform the diagnostic test even if the power-on self test passed.

No Display Troubleshooting

If the E5061B displays nothing despite it is powered from proper ac power line, isolate the failure in accordance with the procedure shown in Figure 2-3.

Connect the keyboard to the E5061B rear panel connector, turn the power on and start trouble isolation. The methods of trouble isolation are described in the procedural step 1 to 6.

Figure 2-3 No display trouble isolation procedure

Keysight E5061B Network Analyzers 23

Troubleshooting No Display Troubleshooting

Step 1. Check fan operation and DC monitor LED

If the rear panel fan (blower) doesn't run, a failure in power supply is assumed. Remove the E5061B outer cover and check if the following LEDs light:

• +3.3 V and +5 V dc monitor LEDs on A50/A60 CPU Module as shown in

Figure 2-4

• LEDs on DSP module as shown in Figure 2-5

Figure 2-4 LEDs on CPU module

Figure 2-5 LEDs on DSP module

To check all the outputs of the power supply, measure the dc voltages at the output lead connectors with a DMM. The dc output voltages and lead color information is provided in the module cover label of the power supply.

Troubleshooting No Display Troubleshooting

Step 2. Check system fan inside.

If the system fan on the chassis inside the E5061B don't run, problem seems in the A51 Measurement I/F board or the flat cable between the A51 Measurement I/F board and CPU module. In this case, remove the E5061B outer cover and make sure whether the fan run or not.

If a beep and a power shutdown occur immediately after power is turned on, there is a possibility that the fan won’t run. The power shutdown occurs the moment the system fan stops by any anomaly. In this case, check the fan that doesn't run.

If the power shutdown occurs without a beep, the problem seems in the A51 Measurement I/F board or the CPU module.

Step 3. Check LED of "Num Lock" key

Press "Num Lock" key on the keyboard. If the LED in the key doesn't light as shown in Figure 2-6, a problem seems in the CPU module.

Figure 2-6 LED of the Num Lock key

Make sure the following before replacing the CPU module.

• Whether all the connections to the A50/A60 CPU Module are normal or not. Check if there is any disconnection or connection working loose.

Step 4. Checking with the external monitor

Connect an external VGA monitor to the VIDEO output on the E5061B rear panel.

• If something is displayed on the external monitor, the problem is present around the LCD. Also check the A52 Front Panel I/F board because the ON/OFF setting of the LCD backlight is controlled by the A52 Front Panel I/F board.

• If nothing is displayed even on the external monitor, the problem seems in the CPU module.

Step 5. Checking flat cable

Check a flat cable between the A50/A60 CPU Module and A52 Front Panel I/F board.

The Windows boot screens are displayed. The Windows boot screens consists of two screens. Each screen is displayed in the order as shown in Figure 2-10. If the Windows boot screens are displayed, it is assumed that the HDD works. While the Window screens are displayed, Windows operating system is starting up.

Figure 2-10 Windows boot screens

If you encounter the following problems, try to reinstall the operating system before replacing the HDD.

• "xxx file is missing" is displayed on DOS screen.

• The Window boot screen is not displayed after the splash screen is displayed.

• Windows always boots up with Safe Mode.

If the E5061B was turned off without shutdown process, Microsoft Scandisk runs while the windows boot screens are displayed. If a serious problem is found in the scandisk, reinstall the operating system. For details of the operating system installation, refer to Appendix B , “System

Recovery,” on page 113. If the operating system still doesn't boot up

properly after reinstallation, replace the HDD.

The operating system automatically checks the device drivers, which are necessary to use the E5061B functions and are installed in the system before the E5061B is shipped from Keysight factory. If the operating system doesn't detect them, a message box is displayed. In this case, install the device driver.

Step 4. Revision and option information

The firmware revision and hardware option information along with copyright declaration is displayed as shown in Figure 2-11. The E5061B firmware quickly starts up just before this display appears. While the revision and option information is displayed, the applications of various devices in the system are initialized.

Figure 2-11 Firmware revision and option information

If the display whited out, entirely blued or appeared with a dialog box, a mass storage problem is suspected. Try to perform the mass storage recovery procedure.

If a message of "Will Shut Down in Five Seconds" is displayed in place of "Initializing.." and the shutdown occurs, the DSP board fails in starting up. The following message may be displayed before the shutdown occurs:

"Fatal Error: Failed to Initialize DSP Driver":

or "Fatal Error: Failed to Initialize DSP":

This message indicates that the DSP board doesn't work or is not properly connected to the DSP board.

"Fatal Error: Failed to Update DSP Code":

If this happened, the DSP board failed in writing DSP program into flash ROM when the firmware was installed first or updated to the newest version. A problem in the DSP or A50 CPU Module is suspected.

Step 5. Measurement view

The measurement view as shown in Figure 2-12 is displayed after the system initialization is completed without problem.

Troubleshooting Using Diagnostic Test

The Keysight E5061B has an diagnostic test function to diagnose the analog measurement section and internal dc power supply voltages. The diagnostic test makes it possible to isolate a faulty board assembly. The following paragraphs describe the procedure to perform the diagnostic test.

Power On Self Test

Power-on self-test always takes place once the E5061B is turned on. When a failure is detected, a message "Power on self test failed" is displayed. The content of the power-on self-test is the same as a part of the diagnostic test program and includes the dc power supply voltage, source PLL synthesizer and level controller (ALC) tests. When the self-test failed, perform the diagnostic test to break down into the individual tests and narrow down failure possibilities.

The following procedure can be used to restart the power-on self test as required.

a. Press key.

b. Click Service Menu and, then, Test M enu in the softkeys.

c. Click Power On Test to restart the test. Wait until the power-on test

ends.

d. The test result (OK or Failed) is displayed in the Power On Test key.

PLL unlock

When a PLL of the frequency synthesizers is unlocked, not the "Power on self test failed" but "Phase lock loop unlocked" message is displayed. If it occurs, A1 Source Module may be faulty.

Contents of the diagnostic test

The diagnostic test contains 8 test groups shown in Table 2-1. Each test group can be performed independently and verifies one of various operating characteristics of the analog measurement section.
