Using Markers
Markers are indicators in the display that you can position on a trace to measure values for the X and Y
axes, such as frequency, power, and time. A Marker always displays its position and, if enabled, will
display the difference between its position and that of the Marker Reference (MR).
You can display up to fi ve markers including the marker reference. Markers can all be placed on the
same trace or they can be placed on different traces. There are two types of Markers: Reference and
Delta Markers. The Marker Reference (labeled MR in the graph) makes absolute measurements and is
also used for calculating differences when Delta readouts are enabled. The Delta Markers (labeled M1
to M4 in the graph) are used to measure other points on the trace or the difference between the Marker
Reference and the Delta marker.
The following table shows the appearance of the four types of marker readouts.
