To Troubleshoot the Instrument
This section describes the basic troubleshooting procedural flow when
servicing the E5063A. The primary procedural tool in this section is the
flowchart. The flowchart contains the entire troubleshooting path from the
failure symptom to the isolation of faulty assembly, and will direct you through
the repair in an orderly manner through the possible failure symptoms.
Reference letters (Yes/No) on the flowchart point to procedural steps that
briefly explain the next troubleshooting method to be performed.
Primary Trouble Isolation
The primary trouble isolation procedure can be performed without
disassembling the E5063A. Figure 1-2 shows the trouble isolation flow chart.
Step 1. Turn the instrument power on.
A few minutes after the E5063A is turned on, the measurement view is
displayed on the screen. The display screen should be similar to Figure 1-11
on page 26.
Step 2. Check the display.
• If no display appears on the LCD after the E5063A is turned on, go to “No
Display Troubleshooting” on page 17.
• If the E5063A stops during booting process despite something being
displayed on the LCD, go to “Booting Process Troubleshooting” on
page 22.
Step 3. Check the basic function.
If the front-panel/keyboard/mouse controls, LCD display, data storage,
remote interface or other function (except the measurement function) does
not work correctly, go to “Function Specific Troubleshooting” on page 30.
Step 4. Check the measurement function.
If the instrument fails performance test, go to “Performance Test failure
Troubleshooting” on page 35.
If the measurement function does not work correctly, perform the diagnostic
tests provided in the E5063A’s service function. If the diagnostic tests fail, go
to “Troubleshooting Using Diagnostic Test” on page 27.
