Description
All the E5071C functions except for VBA and
service functions can be set and controlled via
the front panel keys.
The E5071C equipped with standard option
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 (USB) 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 (USB) on the rear
panel.
An external color monitor can be used to
display the same information as the E5071C
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.
