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
“Performance Test failure
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.
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.
