Inductance1 is one of the measurements available in the Manage Curves dialog box of a Graph Tab. Inductance1 is the inductance of a one-port or two-port circuit assuming a series RL. The units are based on the Inductance units setting. Any parasitics to ground at the selected port are included in the inductance calculation. For example, a one-port circuit might contain an extra parasitic, represented by ''Y'' in the following diagram:
where Leq and Req contain the effect of Y. In this case, the inductance1 calculation gives the equivalent inductance, Leq.
This measurement is not valid for three or more ports. If the circuit is a two-port, the inductance is computed based on shorting the other port to ground as shown below:
Inductance1 is computed as follows:
where Ynn is the y-parameter for selected port n from the Ports section of the Properties pane.
