Auto Scale Trace
Adjusts the "Scale/Div" 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 divi-
sions so that the trace fits onto approx. 80% of the vertical grid. The reference
value is chosen to center the trace in the diagram.
●
In circular diagrams ( "Polar" , "Smith" , "Inv Smith" ), the analyzer re-calculates the
values of the radial divisions so that the diagram is confined to approx. 80% of the
outer circumference. The reference value is set to the value of the outer circumfer-
ence.
Auto scale does not affect the stimulus values and the horizontal axis.
Remote command:

Auto Scale Diagram
Adjusts the "Scale/Div" and the "Ref Value" in order to display all traces in the diagram
area, leaving an appropriate display margin. This scale settings are analogous to the
"Auto Scale Trace" function. The traces in the active diagram area are taken into
account irrespective of their channel assignment.
Ref Value = Marker
See
"Ref Val = Marker / Max = Marker / Min = Marker"
Scale/Div
Sets the value of the vertical diagram divisions in Cartesian diagrams.
"Scale/Div" corresponds to the increment between two consecutive grid lines. The unit
depends on the display format: dB for display format "dB Mag" , degrees for "Phase"
and "Unwr Phase" , ns for "Delay" , U (units) for all other (dimensionless) formats.
"Scale/Div" is not available for circular diagrams ( "Polar" , "Smith" , "Inv Smith" ).

Ref Value
Sets the reference line of a Cartesian diagram or the outer circumference of a circular
diagram.
●
In Cartesian diagrams "Ref Value" defines the value of the reference line, indicated
by a symbol at the right edge of the diagram area. The color of the symbol corre-
sponds to the trace color. As the "Ref Value" is varied, the position of the reference
line ("Ref Pos") is left unchanged, so that the current trace is shifted in vertical
direction. The unit of the "Ref Value" depends on the display format: dB for display
format "dB Mag" , degrees for "Phase" and "Unwr Phase" , ns for "Delay" , U
(units) for all other (dimensionless) formats.
●
In circular diagrams ( "Polar" , "Smith" , "Inv Smith" ), "Ref Value" defines the value
of the outer circumference. Changing "Ref Value" enlarges or scales down the dia-
gram, leaving the center unchanged. The unit is U (units) for all circular diagrams.
