Menu and Key Conventions
The keys labeled Trigger, Disk, and Run are all examples of front-panel keys.
Some front-panel keys bring up menus on the right side of the display screen.
These menus are called softkey menus.
Softkey menus contain functions not available directly by pressing the front-
panel keys. To activate a function on the softkey menu, press the unlabeled
key immediately next to the annotation on the screen. The unlabeled keys
next to the annotations on the display are called softkeys.
Additional functions are listed in blue type above and below some of the front-
panel keys. These functions are called shifted functions. To activate a shifted
function, press the blue front-panel
Shift
key and the front-panel key next to
the desired function.
Throughout this manual front-panel keys are indicated as, for example,
Time-
base
. Softkeys are indicated as, for example,
Mask Align
. The softkeys displayed
depend on the front-panel key pressed and which menu is selected. Shifted
functions are indicated by the front-panel
Shift
key followed by, for example,
the Local function (above the
Stop/Single
front-panel key) and will be shown as
Shift, Local
.
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 highlighted.
To turn the function off, press the softkey so that
Off
is highlighted. An On or
Off softkey function will be indicated throughout this manual as, for example,
Test On
.
A softkey such as
Sweep Triggered Freerun
offers you a choice of functions. In this
case, you could choose
Triggered
by pressing the softkey until
Triggered
is high-
lighted, or choose
Freerun
by pressing the softkey until
Freerun
is highlighted. A
choices softkey will be indicated throughout this manual as, for example,
Sweep Triggered Freerun Triggered
.
When some softkeys, such as
Calibrate probe
, are pressed the first time, a mea-
surement will be made and the result will be provided. Some softkeys, such as
Offset
, require the entry of a numeric value. To enter or change the value, use
the general purpose knob located below the front-panel
Measure
section.
