Alternatives to Scaling
There are several alternatives to manual trace/diagram scaling. Refer to the following
sections:
●
Chapter 5.3.2, "Zooming into the Display" , on page 63
●
Chapter 5.4.4, "Touchscreen Gestures" , on page 82 (zoom stimulus via spreading
and pinching)
●
Chapter 9.2.1, "Stimulus Tab" , on page 289
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
"Auto Scale Trace" on page 295), and irrespective of their channel
assignment.
Auto Scale Diag. (Common Scale)
Similar to "Auto Scale Diagram" on page 295, but scales equally formatted traces
together.
Ref Value = Marker
See "Ref Val = Marker / Max = Marker / Min = Marker" on page 421.
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" ).
