Setting an Event Count (p. 151) (only with the [Expanded] setting)
If triggering occurs too frequently, an event count can be specified so that a trig-
ger is accepted only after the specified number of trigger events has occurred.
Suppressing Noise Effects
Noise near the trigger level can erroneously increment the event count. Set the
trigger filter to avoid such effects.
When Using Noisy Signals for Triggering
Enable the trigger filter (p. 151)
By setting the filter width to prevent triggering on noise, triggering occurs only
when the trigger criteria continue to be met for at least the specified width (inter-
val).
Trigger Level
The noise does not cause triggering.
