●
Use the "Set by Marker" functions ("TRACE > MARKER > Marker Funct"; see
Chapter 3.3.6.6, "Set by Marker"
3.3.6.4
Auto Scale
The "Auto Scale" function adjusts the scale divisions and the reference value so that
the entire trace fits into the diagram. To access "Auto Scale", use one of the following
methods:
●
Select "TRACE > SCALE > Scale Values" to access the "Auto Scale..." settings in
the softtool tab.
●
Tap and hold (with a mouse: right-click) the scale section in the trace list and select
"Auto Scale Trace" from the context menu.
●
Select "Auto Scale..." from the "Trace > Scale > Scale Values" menu.
3.3.6.5
Circular Diagrams
The radial scale of a circular ("Polar", "Smith" or "Inverted Smith") diagram can be
changed with a single linear parameter, the "Ref Value". The reference value defines
the radius of the outer circumference.
●
Increasing the "Ref Value" scales down the polar diagram.
●
Decreasing the "Ref Value" magnifies the polar diagram.
The "Ref Value" is indicated in the scale section of the trace list.
To change the "Ref Value" use one of the following methods:
●
Select "TRACE > SCALE > Scale Values" to access the parameter in the softtool
tab.
●
Tap and hold (with a mouse: right-click) the scale section in the trace list and select
the parameter from the context menu.
Tap and hold the scale section in the trace list for some seconds (with a mouse:
right-click) and select "Ref Value..." from the context menu.
●
Select the parameter from the "Trace > Scale > Scale Values" menu.
●
Use the "Set by Marker" functions; see
Chapter 3.3.6.6, "Set by Marker"
3.3.6.6
Set by Marker
The "Set by Marker" functions are a convenient tool for scaling (in particular: magnify-
ing) diagrams without entering explicit numeric values. You simply place a marker to a
trace point and use the marker values to change the sweep range or move the trace
relative to the vertical axis. The touchscreen or a mouse makes it easier to activate
(touch/click) or move (drag and drop) markers.
