Adding a Marker
Markers can be used on traces to help you visually track up to four signals. Each
marker has the following settings:
•
Type: Provides three options, including:
•
Off
•
Normal: Places a diamond-shaped, colored marker, along with a number,
1-4, on the trace.
•
Delta: Associated with a normal marker. Therefore, a normal marker must
exist prior to creating the delta marker. The delta marker displays the
difference between the normal marker position and the delta marker
position. Only one delta marker can be associated with a given normal
marker. The normal marker must be active when Delta is selected.
•
Marker to Peak: Places the active marker on the current greatest value of the
trace.
•
Marker to Next Peak: Places the active marker on the current second greatest
value of the trace.
•
Marker to Min: Places the active marker on the current lowest value of the trace.
•
Marker to Next Min: Places the active marker on the current second lowest value
of the trace.
