Advanced Trigger Softkeys for Operators with Two Sources
Sharing of Sources
The source definitions for the simple pattern trigger are shared with the
Pattern 1 and Edge 1 sources of the advanced trigger specification. Thus,
changes to the simple pattern trigger will affect that specification, and
changes to Pattern 1 and Edge 1 in the advanced trigger specification will
affect the simple pattern trigger. Defining patterns for the two trigger types
differs. See "To define a pattern trigger" and "To define an advanced trigger."
Logical Combination within Terms
In the pattern trigger, all settings within the pattern are logically ANDed; that
is, all conditions on the pattern, and the edge if specified, must be satisfied
before the analyzer will trigger.
In the advanced trigger, settings within pattern terms are logically ANDed.
Settings within edge terms are logically ORed. This is only important for the
Edge 2 term, where you can define different edge specifications for each
channel. Thus, only one of those edge specifications must be satisfied to
satisfy the edge term.
