Alternatives to Scaling
There are several alternatives to manual trace/diagram scaling. Refer to the following
sections:
●
Chapter 4.3.7, "Scaling Diagrams"
●
Chapter 4.3.3, "Touchscreen Gestures"
on page 38 (zoom stimulus via spreading
and pinching)
●
Auto Scale Trace
Adjusts the "Scale/Div" and the "Ref Value" to display the entire active trace in the dia-
gram area, leaving an appropriate display margin.
●
In Cartesian diagrams, the analyzer recalculates the values of the vertical divisions
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 recalculates 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:
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y[:SCALe]:AUTO
Auto Scale Diagram
Adjusts the "Scale/Div" and the "Ref Value" to display all traces in the diagram area,
leaving an appropriate display margin. All traces in the active diagram are scaled inde-
pendently (see
on page 311), and irrespective of their channel
assignment.
Auto Scale Diag. (Common Scale)
Similar to
on page 311, but scales equally formatted traces
together.
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" ).
