Operation
If B Sweep is delayed by events, the message "PULL SEC/DIV" appears
until the B
Sweep
is
activated.
The
display shows "A" or "B" to identify the sweep delayed, "DBE" to
indicate the Delay-by-Events function,
and
the number of events required to
initiate the sweep, for
example:
A
DBE
1234567

Changing Trigger Settings
2-26
To change trigger settings,
select the desired trigger
by
pushing A/B/MENU.
If A Trigger defines the start event, set the SOURCE, COUPLING, SLOPE,
and
LEVEL controls to define the start event when the NORM
or
SGL
SEa
indicator
is
on.
When
the
MENU
indicator is
on,
the trigger controls affect the B
Trigger, if it defines the
delaying events. If the word recognizer
is
active, change
the word definition with the MENU-SELECT
controls.
