Hi, Does anyone know if there is a way to do a nyquist plot (real Z) vs (Imag Z) in ORCAD SPICE? I would like to obtain this type of plot for a capacitor and/or battery circuit model such as the Randles cell which is R in series with R || C. Once I am able to create nyquist plot, then I can go one and refine/tweak the cell model. I can do a BODE plot just fine and get Phase, Magnitude, and impedance plots all vs freq but I just can't figure out how to do real vs imag. Thanks and hope someone has an idea???
