Characteristic Impedance

Characteristic impedance is a function of numerous parameters, including the size and separation distances between conductors.  Characteristic impedance is defined for each conductor, relative to each other conductor.

Characteristic impedance between any two conductors is mutual.  That is, the characteristic impedance from conductor A to conductor B is equal to the characteristic impedance from conductor B to conductor A.  Thus for two-conductor configurations there is one characteristic impedance.  For three-conductor configurations there are three characteristic impedances.  For four-conductor configurations there are six characteristic impedances.

Select from the Characteristic Impedance list box the conductor pair for which you would like to see the characteristic impedance.  After displaying the graph, the numerical values may be displayed by clicking the Data Table toolbar button.
