ReflectionGraph, ImpedanceGraph, AdmittanceGraph
Create a reflection graph, impedance graph, or admittance graph in a Smith plot. You can add a Reflection Graph, Impedance Graph, and Admittance Graph to a SmithGroup.
Syntax
model.result(<pgtag>).create(<ftag>,"ReflectionGraph");
model.result(<pgtag>).create(<ftag>,"ImpedanceGraph");
model.result(<pgtag>).create(<ftag>,"AdmittanceGraph");
model.result(<pgtag>).feature(<ftag>).set(property,<value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
The reflection graph, impedance graph, and admittance graph are all graphs that appear in a Smith plot. The expressions to use can be S-parameters from an RF simulation, for example. For an impedance plot you can also provide a reference impedance; for an admittance plot you can also provide a reference admittance.
The following properties are available:
