PSpice question.

  1. Jan 30, 2006 #1
    How do I plot equivalent impedance v. frequency? I'm already in AC mode so the frequency is taken care of, but I keep trying to manually write trace expressions for zeq and nothing is working. any tips?

    EDIT: What does the trace expression IP(some element) mean? I think its related.
    EDIT2: I think i got it, I'm just V/I in the trace. I think its working how I want.

    EDIT 3: Not quite, let me provide a few more details. I've modeled the Zeq by a resistor and an inductor in series with an AC voltage source. Is this the way I should model it? Or is there a way I can do it directly from the original circuit. If so, from there how should I plot the Zeq v. freq? I'm especially having trouble thinking about the imaginary part.
