A Quick Tour of the Front Panel
Figure1-2. The instrument display
Softkeys The softkeys are to the right of the display, and instead of placing a label on
the softkey itself, the label is actually located on the display next to the soft-
key. These labels on the display are called menus, and the menu being dis-
played depends on which key has been pressed. For example, pressing Tim e
base brings up the Time Base menu, while pressing Trigger brings up th e Trigger
menu.
There are five types of softkeys, and there are some differences on how each
type of softkey operates. The five types of softkeys are toggle, menu, con tinu-
ous, list, and single choice. Because the Trigger menu contains all five types of
softkeys, it is used over the next few pages to demonstrate the differences
among the softkeys.
When you press the Trigger key, the Trigger softkey menu comes up on the
right side of the display as shown in Figure 1-3.
Toggle softkeys
A typical example of the toggle softkeys is Sweep. A toggle softkey allows you
to choose between two or more selections, and you change selections by
pressing that same softkey. Sweep has choices of either triggered or freerun.
