Circular Diagrams
The radial scale of a circular ("Polar", "Smith" or "Inverted Smith") diagram can be
changed with a single linear parameter, the "Reference Value". The reference value
defines the radius of the outer circumference.
●
Increasing the "Reference Value" scales down the polar diagram.
●
Decreasing the "Reference Value" magnifies the polar diagram.
The "Reference Value" is indicated in the scale section of the trace list.
To change the "Reference Value" use one of the following methods:
●
Press the SCALE key in the TRACE keypad
●
Right-click the scale section in the trace list and select the parameter from the con-
text menu.
●
Select the parameter from the "Trace
–
Scale" menu.
●
Use the marker functions.
The "Autoscale" function also works for polar diagrams.

Using Marker Functions
Marker functions are a convenient tool for scaling (in particular: magnifying) 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. A mouse makes it easier to activate (click) or move (drag and drop) mark-
ers.
To set the sweep range use one of the following methods:
