Claim One:
1. A method for virtually embedding one or more balanced four-port networks into a four-port device under test (DUT), the method comprising the steps of: (a) acquiring a set of scattering-parameters for the DUT; (b) generating a transfer-matrix for the DUT based on the set of scattering-parameters for the DUT; (c) acquiring a set of scattering-parameters for each of the one or more balanced four-port networks to be embedded into the DUT; (d) generating a corresponding transfer-matrix for each of the one or more balanced four-port networks that is to be embedded into the DUT, each transfer-matrix being generated based on the corresponding set of scattering-parameters acquired at step (c); (e) multiplying the transfer-matrix for the DUT with the one or more transfer-matrices generated at step (d) to thereby produce a composite transfer-matrix; and (f) generating a set of composite scattering-parameters based on the composite transfer-matrix, the set of composite scattering-parameters being representative of the DUT with the one or more balanced four-port networks embedded into it.
