On encountering an error in Sync bits (start of block)
On encountering data other than Idle symbol during logical idle on an active lane.
In the Trigger dialog box, select the Simple Trigger radio button.
From the list of trigger events displayed in the left-side pane, expand the Physical Layer Triggers
events category.
Drag and drop the Physical Layer Error(s) event from the left-side to the Select the Trigger(s) to use
section on the right. By using this event, you set up trigger on all the supported physical layer
errors (described in the table above).
