Marker
The Marker key accesses the Marker menu. A marker can be placed on a trace to allow the value of the
trace at the marker point to be determined precisely. The functions in this menu include a 1-of-N selection
of the control mode Normal, Delta, or Off for the selected marker.
Markers may also be used in pairs to read the difference (or delta) between two data points. They can be
used in Marker Functions to do advanced data processing, or to specify operating points in functions like
Signal Track and N dB Points.

Marker Control Mode
There are three control modes for markers:
Normal (POSition) - A marker that can be moved to any point on the X Axis by specifying its X Axis value; its
absolute Y Axis valueis then the value of the trace point at that X Axis value.
D Delta (DELTa) - A marker that can be moved to any point on the X Axis by specifying its X Axis offset from
a reference marker; its absolute Y Axis value is then the value of the trace point at that X Axis value.
Off (OFF) - A marker which is not in use.
