Alternative procedures in realizing of the high frequency power standards with microcalorimeter and thermoelectric power sensors

The paper describes the realization process of the high frequency power standard based on a twin broadband microcalorimeter designed for effective efficiency measurement of coaxial power sensors with indirect heating thermocouples. The presented procedures involve microcalorimeter measurement and calibration steps, parameters computation and systematic errors correction for both long-term and accelerated algorithms. Also, a new method for determining the key parameters of high frequency power standards is proposed.
