The GAP SWEEP SETTINGS softkey opens a sub-menu in
which the parameters for the gap can be selected.
The trigger time corresponds to t = 0. Events occurring
before the trigger time are displayed in negative time.
TRIGGER
LEVEL
The TRIGGER LEVEL softkey activates the entry window for trigger level.
This function corresponds to the setting in the trigger menu.

PRE
TRIGGER
The PRE TRIGGER softkey activates the entry window for the pre-trigger
time. The pre-trigger time defines the separation between the left edge of the
grid and the trigger time (t = 0).
At the same time the gap sweep is switched on (exception : entry t = 0)
The minimum pre-trigger time is −100 s, the maximum pre-trigger time
depends on the sweep time and the trigger to gap time (max = 100 s). The
maximum resolution is 50 ns.
The PRE TRIGGER value can be entered in the frequency domain (span > 0)
as well as in the time domain and GAP SWEEP OFF mode. It is, however,
only effective when the GAP SWEEP measurement is enabled.
