• A r
eference marker(R
ef) defines the reference value for all delta markers.
• A delta marker(Q) indicates the coordinates relative to the reference marker.
• The stimulus value of a discrete marker always coincides with a sweep point.
A special set of markers Mk1 to Mkr4 is provided for bandfilter search mode.
The most common tasks to be performed with markers can be achieved using the Marker menu functions:
• Determine the coordinates of a measurement point on the trace. In polar diagrams where no x-
axis is displayed, markers can be used to retrieve the stimulus value of specific points.
• Determine the difference between two trace points or the relative measurement result (Delta
Mode).
• Convert a complex measurement result into other formats.
Markers also play an important role in performing the following advanced tasks:
• Change the sweep range and the diagram scale (Marker Funct.).
• Search for specific points on the trace (Search).
The Marker menu contains the following functions:
• Marker 1, 2, 3 creates the markers numbered 1, 2, and 3.
• Ref Marker... creates the reference marker which is used to measure relative values and
distances.
• Delta Mode activates the display of the active marker values relative to the reference marker.
• Ref.Marker -> Marker places the reference marker to the position of the active marker.
• All Mkrs Off removes all markers from all traces of the active setup.
• Mkr Format defines an output format for the (complex) marker values.
• More Mkrs opens a submenu to create the markers numbered 4 to 10.
• Coupled Mkrs couples the markers on different traces.
• Discrete Mkrs turns the active marker into a discrete marker and vice versa.
• Mkr Properties... opens a dialog with extended marker settings.
• Export Mkrs... exports the marker values to an ASCII file.
Toggle functions in the Marker menu
Some of the Marker functions toggle between two alternative states when they are pressed repeatedly:
