MODULATION—This menu provides you
with access to sub-menus that let you select
the type of signal modulation (AM, FM, or
Square Wave) and control the option settings
for each type.
SYSTEM—This menu provides you with ac-
cess to sub-menus that let you (1) reset the in-
strument to factory-selected default values; (2)
configure the front panel, rear panel, RF, and
GPIB; (3) set incremental sizes for editing fre-
quency, power level, and time parameters; (4)
save or recall instrument setups; (5) disable
front panel data display; and (6) perform in-
strument self-test.
Main Menu Key Cursor
With the exception of the
SYSTEM
key, when any
main menu key is pressed, the main menu that is
displayed contains a cursor positioned adjacent to
the pressed key (Figure 3-2). The cursor is displayed
on all sub-menus of the current menu until a differ-
ent main menu key is pressed.
When the
SYSTEM
key is pressed, the System
menu is displayed. The System menu and its sub-
menus do not contain a main menu key cursor.
Menu Soft-Keys
As shown on the left, five menu soft-keys are lo-
cated below the data display and five menu soft-
keys are located to the right of the data display. In
general, the menu soft-keys located below the data
display select a sub-menu of the current main (top-
level) menu display; the menu soft-keys located to
the right of the data display either control a func-
tion on the current menu display or select an addi-
tional sub-menu. Menu labels that identify the
current function of each soft-key are shown on the
menu display adjacent to the soft-keys.
