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...
Saturable reactor or transductor used as a magnetic modulator or amplifier for the measurement of the small value DC output signal of a transducer may suffer from error due to the fact that a part of the current drawn from the transducer by the transductor unit is utilized to magnetize the core material. In this paper a modified two core saturable reactor circuit has been proposed to eliminate this...
