I'm having a problem using adaptive frequency sweep. The rational fitting model sometimes does not select enough frequencies to accurately model the structure. The S11 plot below shows where I am getting a linearly interpolated S11 values instead of a smooth curve. I remember in previous version there was a parameter which controlled the convergence of the rational fitting model, but I don't see it in EmPro 17. Also, I would prefer to control the rational fitting model convergence parameter using a Python API function call.
