Abstract
An apparatus (310) for characterizing a multiport circuit (390) includes a signal generator (320) and a circuit interface apparatus (330, 340, 350). The signal generator (320) has an output (329) selectable from among a set of composite signals that are linearly independent. The circuit interface apparatus (330, 340, 350) is coupled to the signal generator (320) and has an output (319) of a set of circuit stimulus signals derived from the set of composite signals, which set of circuit stimulus signals are linearly independent, and which together form a complete basis for describing any response for the multiport circuit (390). The circuit interface apparatus (330, 340, 350) has measurement circuitry for measuring circuit response of the multiport circuit (390). Preferably, the circuit interface apparatus (330, 340, 350) is formed from multiple two-port test sets.
