The following methods are available:
"Time"
Defines the holdoff directly as a time period. The next trigger occurs
only after the "Holdoff time" has passed.
"Events"
Defines the holdoff as a number of trigger events. The next trigger
only occurs when this number of events is reached. The number of
triggers to be skipped is defined in "Holdoff events".
"Random"
Defines the holdoff as a random time limited by "Random minimum
time" and "Random maximum time". For each acquisition cycle, the
instrument selects a new random holdoff time from the specified
range.
Random holdoff prevents synchronization to discover effects invisible
with synchronized triggering, for example, the features of a pulse
train.
"Auto"
The holdoff time is calculated automatically based on the current hori-
zontal scale.
"Auto time scaling" defines the factor the horizontal scale is multipied
with.
"Auto time" shows the resulting holdoff time: Auto time = Auto time
scaling * Horizontal scale.
"Off"
No holdoff

6.5 Noise Reject
The rejection of noise by setting a hysteresis avoids unwanted trigger events caused
by noise oscillation around the trigger level.
You can select the hysteresis mode and value for each channel separately, or couple
the trigger levels and set the same hysteresis for channels. The hysteresis of the exter-
nal trigger input is an independent value, and it is not affected by level coupling.
