FRONT PANEL AND REAR PANEL
DESCRIPTION
3.2.1
Front Panel Description
The front
panel
of the Model
3930A is shown
in
Figure3-1.
The front panel is made up of a two-line,
40-character
liquid
crystal display and a control panel
with a built-in
flat keyboard. The liquid
crystal display
presents information
useful
for the operation
of the
Model 3930A, such as the value of each parameter and
the range of permissible
parameter values.
The keyboard includes a SHIFT key, which gives certain
other keys secondary functions.
A key which is shaded
with the same color as the SHIFT key requires that you
press SHIFT first before accessing the function
of that
particular
key.
Most settings are maintained
in battery backed-up mem-
ory. As a result, the Model 3930A automatically
assumes
the previous settings when the power is first turned on.
