Dropout ← Trigger dialog box (2)
Sets the dropout time. The dropout time prevents the trigger system from being activated
by signal excursions prior to the trigger event targeted. The parameter is set to a value
that is slightly higher than the maximum duration of power drops that are supposed to
execute triggering.
In contrast to the "Holdoff" parameter which is referenced to the active slope (trigger
event), the dropout time takes effect if the passive slope of the trigger signal crosses the
trigger threshold.

Trigger dialog box (3)
The third page of the trigger dialog box covers the hysteresis and holdoff parameters.

Tabs for selecting the sensor.
Note: In remote-control commands, select the sensor with the suffix in command
SENSe<[1]..4>:...
, i.e. choose suffix
1
for channel A, channel
2
for B, and so on.
Hysteresis ← Trigger dialog box (3)
Sets the trigger hysteresis. The trigger hysteresis prevents the trigger system from being
activated too early if the trigger threshold is slightly underranged or exceeded. Before
triggering can occur again, the signal level must be lower (higher) than the trigger level
minus (plus) hysteresis.
Modifications of the trigger hysteresis are effective immediately (see
​
chapter 3.5, "Dialog
boxes and their controls" , on page 53).

Holdoff ← Trigger dialog box (3)
Sets the holdoff time. The holdoff time starts with the trigger event. During holdoff time
other trigger events are suppressed.
