From Trigger / Start / X Marker Fields
The from Trigger/Start/X marker field is used to access the selection pop-up
menu for the start point of the X and O marker occurrence counters.
The start points available for the green X marker are either the trace start
point or the trigger point.
The start points available for the yellow O marker are either the trace start
point, trigger point, or the X-marker.
If the marker pattern can not be found, a message appears at the top of the
display indicating the search failed. If the O marker is referenced from the
X marker and the X marker is not found, the search for both markers will fail.
