Adding or Removing 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, which places a diamond-shaped, colored marker, along with a number, 1-4, on the trace.
 Delta, is 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. This key is only enabled when your currently selected marker is of type Normal or Delta.
 Marker to Next Peak: Places the active marker on the current next greatest value of the trace. This key is only enabled after you have performed a Marker to Peak search, and when the currently selected marker is of type Normal or Delta.
 Center Freq to Marker: Changes the center frequency to locate the current marker in the center of the trace.
 Ref Level to Marker: Scrolls the trace to place the marker at the top of the screen. To reset the reference level, choose [Level/Location] [Autoscale].
