Scattering parameter travelling-wave magnitude calibration system and method

摘要

A calibration system and method determines magnitudes of traveling-waves at a non-coaxial plane of a scattering (S) parameter measurement device that includes an adapter link between the non-coaxial plane and a coaxial plane. A calibration is conducted at an interface between the adapter link and the coaxial plane to derive coaxial error terms for the S-parameter measurement device. In addition, a power meter measurement is conducted at the coaxial plane to obtain power wave measurements using the coaxial error terms. A calibration is also conducted at an interface between the adapter link and the non-coaxial plane to derive non-coaxial error terms for the S-parameter measurement device. The power wave measurements, coaxial error terms and non-coaxial error terms are used to calculate the magnitude of one of the traveling-waves at the non-coaxial plane.
