Function Specific Troubleshooting
If the E5052B exhibits a failure symptom that is related to a specific function or control
such as a front panel key control, display, data storage, remote control interface, printer
interface, external trigger, external keyboard or mouse, isolate the trouble using the
Function Specific Troubleshooting procedures described below. The major functions of the
E5052B and the troubleshooting procedure for each function are shown in Table 4-2.
Table 4-2 Major functions and troubleshooting procedures
Function Description Troubleshooting
Front panel keys All the E5052B functions except for VBA and
service functions can be set and controlled via the
front panel keys.
Refer to “To Check the Front
Panel” on page 72.
Touch panel The E5052B has a touch screen display that allows
all the functions in the menu bars, setup windows
and dialog boxes to be set by a touch to the screen
panel.
Refer to “To Check the
Touch Panel” on page 73.
LCD display Almost all the information including the
measurement value, setup state, result data
processing, menu bar, softkey label and others are
indicated on the 10.4-inch color LCD display.
Refer to “To Check the
LCD” on page 73.
External keyboard The external keyboard can be used for the entry of
numerical and character data when it is connected
to the keyboard interface connector (USB) on the

Video output An external color monitor can be used to display
the same information as the E5052B LCD display,
when it is connected to the Video output connector
(24-pin D-Sub) on the rear panel.
Refer to “To Check the
Video output” on page 74.
External trigger input The external trigger input terminal (BNC) on the
rear panel allows an external trigger source to be
used for measurement trigger.
Refer to “To Check the
External Trigger Input” on
page 74.
GPIB Interface The GPIB compatibility allows the E5052B to be
operated as a talker/listener on IEEE 488 interface
bus.
Refer to “To Check the
GPIB” on page 75.
24-bit I/O port The 24-bit I/O port can be used to transfer a
comparator decision output data to and perform
timing synchronization with an external handler.
