Using Marker Functions
Marker functions are a convenient tool for scaling (in particular: magnifying) diagrams
without entering explicit numeric values. You simply place a marker to a trace point
and use the marker values to change the sweep range or move the trace relative to the
vertical axis. A mouse makes it easier to activate (click) or move (drag and drop) mark-
ers.
To set the sweep range use one of the following methods:
Define "Start" and "Stop" values
1. Create two normal markers, e.g. the markers Mkr 1 and Mkr 2, and place them to
the desired start and stop values of the sweep range.
2. Activate "M 1" and click "Trace
–
Marker Funct.
–
Start = Marker".
3. Activate "M 2" and click "Trace
–
Marker Funct.
–
Stop = Marker".
Use a definite "Span"
1. Create a marker and set it to delta mode.
