Troubleshooting

To Troubleshoot the Instrument

This section describes basic procedural flow of troubleshooting when servicing the

E5061A/E5062A. 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

E5061A/E5062A. Figure 4-2 shows the trouble isolation flow chart.

Step 1. Turn the instrument power on

About a few minutes after the E5061A/E5062A is turned on, the measurement view is

displayed on the screen. The display on the screen should be similar to Figure 4-9,

“Measurement view,” on page 99.

Step 2. Check the display

• If no display appears on the LCD after the E5061A/E5062A is turned on, go to “No

Display troubleshooting” on page 92.

• If the E5061A/E5062A stops in booting process despite something being displayed on

the LCD, go to “Booting Process Troubleshooting” on page 95.

• The power-on self test is performed once automatically after the E5061A/E5062A

measurement view is displayed. If the power-on self test fails, go to “Troubleshooting

Using Diagnostic Test” on page 100.

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 106.

Step 4. Check the measurement function

If the instrument fails performance tests, go to “Performance test failure troubleshooting”

on page 118.

If the measurement function does not work correctly, perform the diagnostic test provided

in the E5061A/E5062A's service function. When the diagnostic test fails, go to “Diagnostic

Test Failure Troubleshooting” on page 104.

NOTE 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.
