2D and Circuit Smith Chart

A Smith chart is a 2D polar plot of S-parameters upon which a normalized impedance grid has been superimposed. Following is the general procedure for creating a Smith chart of results:

1. Click Product > Results or, on the Project Manager window, expand the Project Tree and [active design folder], then right-click Results. Navigate to the appropriate report type and select Smith Chart to open the New Report window.
2. In the Trace tab Polar Component group box, specify the information to plot:

1. From the Category dropdown menu, select the type of information to plot.
2. From the Quantity list, click the values to plot. Use Ctrl+click to make multiple selections.
3. In the Function group box, click the mathematical function to apply to the quantity for the plot.
4. The Value field displays the currently specified Quantity and Function. Edit this field directly. Note that invalid expressions are displayed in red.
5. Range Function — opens the Set Range Function window. This applies currently specified Quantity and Function.

3. Click New Report.

This creates a new report in Project Tree, displays the report with the defined trace, and enables Add Trace on the Report window.

The function of the selected quantity is plotted against the values you specified on a polar plot. Each circle on the plot is labeled with values of R, measuring normalized resistance, and each line is labeled with values of X, measuring normalized reactance. The plot is listed under Results in the Project Manager window and the traces are listed under the plot. When you select the traces or plots, their properties are displayed in the Properties window. These properties can be edited directly to modify the plot.

4. Optionally, add another trace to the plot by following the procedure above, using Add Trace rather than New Report.
