Softkey
Overview
The keys labeled AMPLITUDE, FREQUENCY, CAL, and MKR are all examples
of front-panel keys. Pressing most front-panel keys accesses menus of
functions that are displayed along the right side of the display. These menus
are called softkey menus.
Softkey menus list functions other than those accessed directly by the
front-panel keys. To activate a function on the softkey menu, press the
unlabeled key immediately to the right of the annotation on the screen.
The unlabeled keys next to the annotation on the display screen are called
softkeys.
Front-panel keys are designated with a box around the key label, for
example,
[AMPLITUDE];
softkeys are designated by shading on the key label,
for example,
REF
LUL
. The softkeys that are displayed depend on which
front-panel key is pressed and which menu level is enabled.
If a softkey function’s value can be changed, it is called an active function.
The function label of the active function appears in inverse video. For
example, press
c-1.
This calls up the softkey menu of related
amplitude functions. Note the function labeled
REF
LVL appears in inverse
video. REF LVL also appears in the active function block, indicating that it is
the active amplitude function and can now be changed using any of the data
entry controls.
A softkey with ON and OFF in its label can be used to turn the softkey’s
function on or off. To turn the function on, press the softkey so that ON
is underlined. To turn the function off, press the softkey so that OFF is
underlined. The following example demonstrates how an ON or OFF softkey
function will be annotated: VID AVG
ON
OFF (ON).
A function with AUTO and MAN in the label can either be auto-coupled or
have its value manually changed. The function’s value can be changed
manually by pressing the softkey until MAN is underlined, and then changing
its value with the numeric keypad, knob, or step keys. To auto-couple
a function, press the softkey so that AUTO is underlined. The following
example demonstrates how an AUTO or MAN softkey function will be
annotated:
ATTEN
AUTO
MAN (AUTO).
A summary of all front-panel keys and their related softkeys can be found in
Chapter 7, “Key Menus”.
