Trigger Holdoff
Holdoff is an optional, additional condition of Edge trigger. It can be set either as a
period of time or as an event count. Holdoff disables the trigger circuit for a given
period of time or events after the last trigger occurred.
Events are the number of occasions on which the trigger condition is met. The
trigger occurs again when the holdoff elapses and the edge trigger’s other
conditions (for level, slope, etc.) are met.
Use holdoff to obtain a stable trigger on complex, but repetitive, waveforms. For
example, if there is a signal with multiple edges prior to the edge you wish to
trigger on, you could set the holdoff to equal the number of edges preceding the
desired triggering edge.

Basic Triggers
Edge
Use Edge trigger for simple, repetitive signals. This trigger is activated
by basic waveform features or conditions such as a positive or negative
slope, and hold-off

slope, and hold-off
Width
Width trigger allows you to define a positive or negative-going pulse
width bounded by a voltage level, above or below which a trigger
occurs. Or, you can specify a pulse width and voltage range, within or
outside of which a trigger occurs.

Qualified
The Qualified (A-B) trigger allows arming of the trigger on Event A and
triggering on Event B. If the arming event is a Pattern that occurs once
(Pattern) or that occurs and stays satisfied (PatState), then the
triggering event can be an Edge, Width, Glitch, or Interval condition.
This functionality is identical to LeCroy's previous Qualify and State
triggers, but presented in a different UI.

Pattern
Pattern trigger enables triggering on a logical combination (pattern) of
five inputs: CH1, CH2, CH3, CH4, and EXT. You have a choice of four
Boolean operators (AND, NAND, OR, NOR), and you can stipulate the
high or low voltage logic level for each input independently.

Note: When used with an optional Mixed Signal module the pattern
trigger supports 18 or 36 digital channels along with the analog
oscilloscope channels.
