Marconi Instruments 2040 - Utilities; Adjusting the Display

UTILITIES
The utilities options are accessible from two primary menus, Utilities Selection Menu 1
and Utilities Selection Menu 2. When
a selection is made from either of these menus and
[UTIL]
is subsequently pressed, the primary menu is re-displayed. However, if instead a
selection is made and then one of the other hard keys
e.g.
[SWEEP] is pressed, pressing [UTIL]
subsequently once returns
to the sub-menu, pressing it again returns to the primary menu. This
provides an operating short-cut in that it allows a sub-menu to
be
re-accessed without
first
having
to go
again through
the primary menu. This scheme does not apply to the [TIME
&
DATE]
soft key
or
to the [Sig Gen] hard key. The display for Utilities Selection Menu 1 is
shown in Fig.
3-1-26.
To obtain Utilities
Selection Menu 2 from the menu, press
[Utils. Menu
2].
