Multisim-How to calculate impedance of OP Amp

Hi All,

How can I calculate equivalent input impedance Zeq (in nF) of following circuit using multiSim. R1=1.7K ohm R2=44.5K ohm  C=1nF.

Configure the source circuit at the input port where you want to determine Zeq such that you can measure or calculate both the votlage and the current.  Since your input impedance is complex you need to measure both amplitude and phase.  Ohm's Law is your friend.
