Trigger Setup
The
Trigger
tab in the analysis project dialog allows you to specify when the analyzer
completes a data capture. Three trigger modes are available: The default
Don’t
care
(Snapshot),
Manual
Trig,
and
Pattern.
When data capture starts with
Don’t
care
(Snapshot)
selected, the analyzer triggers on
the first data pattern on the bus.
Starting a data capture with
Pattern
selected triggers when specific pattern(s) are
detected in the captured data stream. The following three ways can trigger the analyzer
with
Pattern
selected.
Trigger on any pattern (Any Trigger Mode)
External Trigger
Trigger on a sequence of patterns (Sequential Trigger Mode)
Snapshot Mode
To trigger immediately on any pattern, check the
Don’t
care
(Snapshot)
button.
