Logic Analyzer Concepts
The Trigger Sequence
Trigger on specification. If there are branch and storage
specifications for each sequence level, what does the trigger term
mean? The trigger term is a special sequence-advance specification in
that, when found, it locks the contents of analyzer acquisition memory.
The trigger can be positioned at the beginning, middle, or end of
acquisition memory.
The trigger specification can look like the following:
TRIGGER on "<TERM>" <OCCURS> times
TRIGGER on "<TERM>" <TIME PERIOD>
If the trigger term is found <OCCURS> times, or if the trigger term
remains stable for <TIME PERIOD>, the trigger is captured in memory.
Then the analyzer advances to the next sequence level. If you want to
capture activity after the trigger is captured, define an additional
sequence level and specify the desired storage qualification for post-
trigger activity (for example, store anystate).
