Sequential Trigger Mode
In Sequential Trigger mode, triggering occurs whenever the system detects a specific
sequence of patterns. Defining the triggering patterns sets the sequence order. You must
define at least two patterns to enable selection of Sequential Trigger mode.
Note: Patterns, such as Primitives and Symbols or Frames, occurring very close together on different
ports can cause false triggers.
To define a triggering sequence, select more than one pattern, then check the
Define Sequential Trigger Mode check box. See
“Define Sequential Trigger Mode” on
page 80 for more information.

SAS vs. SATA: SATA Dialog has different patterns.
Timer
The sequential triggering mode offers the option of triggering on a timer or inserting a
timer in the triggering sequence to delay detection of the next pattern in the sequence.
To insert a timer in the trigger list, double‐click Timer to open the Timer dialog.
