Three-State Trigger Example - Arm, Trigger or Rollback
In this example, before the arm the analyzer captures Any Traffic . After the SMP Request Frame is
seen, the analyzer will continue to capture
Any traffic
. The default setting for the Pre-Armed and
Armed states is to capture Any Traffic .
The port-pair continues to capture data until either the trigger or rollback condition is met. If the
trigger event of
Write Command is encountered in the data stream, all ports in the domain
continue capture 50% more of the trace size and then all ports stop. If the timeout of 28 sec. is
reached, the state rolls back to the Pre-Armed state.
The percentage of the buffer containing data immediately after the Trigger event is controlled by
the Post Trigger Fill setting on the
Capture and Trigger Setup tab. If the Post Trigger Fill
position is set to 50%, then 50% of the buffer will contain data seen after the Trigger event.
Press the Apply button to load the configuration to the selected analyzer port.
