Description

In the Pattern trigger mode (see :TRIGger:SEQuence:MODE), this command selects the time the pattern must be present for in order to cause a trigger.

When the pattern consists of logic levels only, you have these options:

• ENTered — Triggers on the edge of the signal that makes the pattern true.
• EXITed — Triggers on the edge of the signal that makes the pattern false.
• LTHan — Triggers when the pattern is present for less than the specified :TRIGger:SEQuence:PATTern:TIME.
• GTEXit — When the pattern is present for greater than the specified :TRIGger:SEQuence:PATTern:TIME, triggers when the pattern ends (on the signal edge that makes the pattern invalid).
• GTTout — When the pattern is present for greater than the specified :TRIGger:SEQuence:PATTern:TIME, triggers when the time is exceeded.
• RINSide — Trigger when the pattern is present for a time within the range specified by the :TRIGger:SEQuence:PATTern:RSTart and :TRIGger:SEQuence:PATTern:REND values. The trigger occurs on the signal edge that makes the pattern invalid (like "on Exit").
• ROUTside — Trigger when the pattern is present for a time outside the range specified by the :TRIGger:SEQuence:PATTern:RSTart and :TRIGger:SEQuence:PATTern:REND values.

When the pattern includes an edge identifier, you have these options:

• TPANd — The trigger point is the edge AND the pattern on the remaining channels.
• TPNand — The trigger point is the edge AND NOT the pattern on the remaining channels.

Edges are identified when a signal passes through the trigger threshold voltage. The direction of the edge is determined based on hysteresis around the trigger threshold.

The combination of an edge and a pattern is known as a State trigger.
