Patent ID: 6982561

Claim:
A method for determining magnitudes of travelling-waves at a non-coaxial plane of a scattering (S) parameter measurement device, the S-parameter measurement device including an adapter link between the non-coaxial plane and a coaxial plane, the method comprising: conducting a calibration at an interface between the adapter link and the coaxial plane to derive coaxial error terms for the S-parameter measurement device; conducting a power meter measurement at the coaxial plane to obtain power wave measurements using the coaxial error terms; conducting a calibration at an interface between the adapter link and the non-coaxial plane to derive non-coaxial error terms for the S-parameter measurement device; and calculating a magnitude of a select one of the travelling-waves at the non-coaxial plane using the coaxial error terms, the power wave measurements and the non-coaxial error terms.
