The easiest method is to set the main excitation voltage to zero and drive the output with a one amp AC current. Then you plot the voltage at the output and view it on a linear scale and the output in volts will be the output Z in ohms.
If it makes you feel better you can enter an expression to divide the voltage output by the Current you will get the impedance listed in ohms on the vertical scale.
