Input Impedance

Input Impedance is one of the measurements available in the Manage Curves dialog box of a Graph Tab. Input Impedance, Zin, is calculated from the circuit s-parameters as follows:

where n is the port number selected in the Properties pane of the Manage Curves dialog box below. Z0* is the conjugate of the specified termination for port n.

Please see the Measurement Properties topic for an explanation of each field in this dialog box.
