•
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.
•
Maximize
maximizes the active diagram area.
•
Overlay All
displays all traces in one diagram area.
•
Split All
displays every trace in a separate diagram area.
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.,
no
Ref. Position
, and no
Max
and
Min
values
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).
Relations between the scaling parameters
The scaling parameters
Scale / Div, Ref Value, Ref Position, Max, Min
are coupled together in the
following manner:
Max – Min = Scale / Div * <Number of graticule divisions>
Max = Ref Value when Ref Position is 10
Min = Ref Value when Ref Position is 0
The Marker -> provide a convenient alternative to manual diagram scaling.
Autoscale
Adjusts the
Scale Divisions
and the
Ref. Value
in order
to display the entire active trace in the diagram
area, leaving an appropriate display margin.
•
In Cartesian diagrams, the analyzer re-calculates the values of the vertical divisions so that the
trace fits onto 80% of the vertical grid. The reference value is chosen to center the trace in the
diagram.
