To Troubleshoot the Instrument
This section describes basic procedural flow of troubleshooting when servicing the
E5052B. 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
E5052B.
Figure 4-1
Step 1. Turn the instrument power on
About a few minutes after the E5052B is turned on, the measurement view is displayed on
the screen. The display on the screen should be similar to
on page
63.
Step 2. Check the display
•
If no display appears on the LCD after the E5052B is turned on, go to
troubleshooting" on page
•
If the E5052B stops in booting process despite something being displayed on the LCD,
go to
"Booting Process Troubleshooting" on page
•
The power-on self test is performed once automatically before the measurement starts.
If the power-on self test fails, go to
page
64.
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
Specific Troubleshooting" on page
Step 4. Check the measurement function
If the instrument fails performance tests, go to
on page
78.
If the measurement function does not work correctly, perform the Power On Test provided
in the E5052B's service function. When the Power On Test fails, go to
Failure Troubleshooting" on page
