Scale
The Scale settings define how the current trace is presented in the diagram selected in the Format
submenu.
• Autoscale adjusts the diagram scale in order to display the entire active trace in the diagram
area.
• Autoscale All adjusts the diagram scale in order to display all traces in the diagram area.
• Scale/Div. sets the value of the vertical diagram divisions.
• Ref. Value sets the reference line of a Cartesian diagram or the outer circumference of a polar
diagram.
• Ref. Position defines the position of the reference line in a Cartesian diagram.
• Ref Val = Marker sets the reference value equal to the active marker value.
The Scale settings are closely related to the settings in the Format submenu and in the Display menu.
All of them have an influence on the way the analyzer presents data on the screen.
The Scale settings depend on the diagram type (Trace – Format) because not all diagrams can be
scaled in the same way:
• In Cartesian diagrams, all scale settings are available.
• In circular diagrams, no Scale/Div. and no Ref. Position can be defined.
The default scale is activated automatically when a display format (diagram type) is selected. Scale
settings that are not compatible with the current display format are disabled (grayed).
The Marker Functions provide a convenient alternative to manual diagram scaling.
