74 Sierra M124 SAS/SATA Protocol Analyzer User Manual
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.
Figure 2.36: Default Trigger Selected
Manual Trigger Mode
To perform a manual trigger, check the Manual Trig radio button. In the Manual Trigger
mode, the analyzer captures bus traffic continually from when you use the Manual
Trigger until you click the Stop Recording button (on the analyzer toolbar), which triggers
the analyzer. Clicking the Manual Trigger button on the application toolbar creates a
Trigger Event and uploads the trace with the specified trigger position.
Any Trigger in Pattern Mode
In Pattern mode, the Analyzer triggers whenever any of the patterns selected for
triggering occurs (an OR condition). The procedure for selecting trigger parameters is
identical to that for selecting capture parameters. All items selected for triggering appear
in the Project Tree.
To define patterns for triggering, check the Pattern button in the Trigger dialog (see
Figure 2.37 on page 75 .)
