Cable Connector Impedance

Many cable harnesses employ cable connectors to terminal boxes. The presence of cable connectors usually requires different impedance matrices to characterize the ends of cable branches where the connectors are employed. Different capacitance, inductance, resistance, and conductance matrices can be specified for connectors. In MHARNESS® the cable connector impedance parameters must be manually defined.

The specification of connectors does not increase the length of the cable. Connectors are always associated with the last finite difference cell on the ends of each meshed cable. If cable connectors are not specified, then the ends of each meshed cable assume the properties of the main portion of the cable.

The cable segment line impedance parameter values are supplied in units per length. The connector impedance parameters, however, should consist of the total value. The associated per unit length value is computed internally.
