To Troubleshoot the Instrument
This section describes basic procedural flow of troubleshooting when servicing the
E5052A. 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
E5052A. Figure 4-2 shows the trouble isolation flow chart.
Step 1. Turn the instrument power on
About a few minutes after the E5052A 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 95.
Step 2. Check the display
• If no display appears on the LCD after the E5052A is turned on, go to "No Display
troubleshooting" on page 88.
• If the E5052A stops in booting process despite something being displayed on the LCD,
go to "Booting Process Troubleshooting" on page 91.
• The power-on self test is performed once automatically before the measurement starts.
If the power-on self test fails, go to "Troubleshooting Using Service Function" on
page 96.
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 100.
Step 4. Check the measurement function
If the instrument fails performance tests, go to "Performance test failure troubleshooting"
on page 112.
If the measurement function does not work correctly, perform the Power On Test provided
in the E5052A's service function. When the Power On Test fails, go to "Power On Test
Failure Troubleshooting" on page 99.
