摘要：
A new power sensor calibration system incorporating a vector network analyzer (VNA) has been developed. The vector-based system is able to account for the various impedance mismatches at the calibration test port, thus mathematically eliminating the mismatch uncertainty component of the power calibration. With scalar-based systems, this component is a major contributor to the overall calibration uncertainty. The new vector-based system reduces the overall calibration uncertainty significantly. This article discusses the new system in detail and presents measurement data and associated uncertainties.
