detected in the captured data stream. The following three ways can trigger the analyzer

 External Trigger
 Trigger on a sequence of patterns (Sequential Trigger Mode)
Snapshot Mode
To trigger immediately on any pattern, check the Snapshot button.
Figure 2.84: Default Trigger Snapshot Mode Selected
Manual Trigger
In the Manual Trigger mode, the analyzer captures bus traffic continually from when you
use the Manual Trigger until you click the Stop Hardware button (on the analyzer
toolbar), which triggers the analyzer.
Timer
See
“Timer” on page 67 for more information.
Defining Patterns
The definition of patterns for the sequential trigger mode is identical to the Pattern
mode, with the following exception:
In sequential triggering mode, all the pattern dialogs display the option for setting to
count the expected number of occurrences on each link. This allows you to specify the
number of times that the pattern must occur before triggering or proceeding in the
trigger sequence.
Figure 2.85: Number of Occurrences
Note: The Events on each link are counted independently, causing a trigger whenever the number of
occurrences on any link equals the specified value.
