Technique for Assessing the Reproduction Error of the Complex Reflection Coefficient Unit in Waveguides

A technique for determining the standard deviation and non-excluded systematic error in reproducing the complex reflection coefficient unit in waveguides has been proposed and a corresponding technique has been developed. It has been established that the reproduction error depends on the value of the measured complex reflection coefficient for a specific frequency, and its dominant component is due to the error in measuring the depth of short-circuit references. It is advisable to use the obtained results of determining the reproduction error in the form of tables in order to assess the error in the measurement results of the complex reflection coefficient. The proposed technique can be used to determine the accuracy indicators of measurements of the complex reflection coefficient when creating the State Primary Standard for the complex reflection coefficient unit in standardized waveguides at frequencies up to 178.4 GHz.
