Development of a system to ensure the uniformity of measurements of the power of electromagnetic oscillations in the field of millimeter wavelengths

The renewal of the fleet of radio engineering and electromagnetic measuring instruments is due to the introduction of high-tech technologies, the modernization of radio electronic industry products. The use of a new generation component base in modern measuring instruments has made it possible to improve parameters such as measurement ranges and frequencies, and instrumental error. As a result, the error of ultrahigh frequency power measuring instruments is limited by the metrological characteristics of working standards and measurement methods used in the transmission of a unit. The research is aimed at improving the theory and methodology of reproduction and transmission of a unit of power of electromagnetic oscillations from the state primary standard. A system of requirements for primary and working standards has been formed, taking into account the use of measurement results of complex reflection coefficients to reduce the error of misalignment and the application of stability criteria. The results of scientific research on the creation of primary, secondary, working standards and measuring instruments for the power of electromagnetic oscillations in the range from 37.5 GHz to 178.4 GHz are presented. The concept of constructing a state verification scheme for power measuring instruments using borrowed working standards of units of complex reflection and transmission coefficients, attenuation, and frequency is proposed. The main elements of the system being created for the reproduction and transmission of ultrahigh frequency power units, including the state primary standard with an extended frequency range, working standards, power meters, ensure improved measurement accuracy during the development and testing of modern radio engineering complexes.
