Description
All the E5052A functions except for VBA and
service functions can be set and controlled via the
front panel keys.
The E5052A 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.
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.
The external keyboard can be used for the entry of
numerical and character data when it is connected
to the keyboard interface connector (PS-2) on the
rear panel.
The mouse can be used to move the pointer on the
LCD display, select a function and change a
setting, when it is connected to the mouse interface
connector (PS-2) on the rear panel.
The 3.5-inch floppy disk drive on the front panel is
used to save the E5052A setup state and
measurement data in a 3.5-inch, 1.4 MB floppy
disk in MS-DOS compatible format.
An external color monitor can be used to display
the same information as the E5052A LCD display,
when it is connected to the Video output connector
(24-pin D-Sub) on the rear panel.
The external trigger input terminal (BNC) on the
rear panel allows an external trigger source to be
used for measurement trigger.
The LAN interface port on the rear panel allows
the E5052A to be connected to 10/100 Base-T
Ethernet.
