Hi,

in most analog design environments the Smith chart is used only as pure post-processing tool for result display but not for real design, e.g. with entering a circuit in the Smith chart. That is missing! For Windows there are quite many good Smith chart tools like Smith from Berne University of Applied Sciences or CSmith from weberconnect.de. Even some old DOS programs are better wrt compared to Viva or pltool.
