Abstract

This paper describes hardware and software improvements of the INRIM coaxial microcalorimeter together with their effect on the primary power standard realization in the frequency band 0.05 - 40 GHz. A better temperature and power stabilization turned out to provide an improved signal/noise ratio and a drift reduction in every working condition of the microcalorimeter. Results are presented in form of a 2.92 mm thermoelectric power sensor calibration together with graphs that show the improved stability and repeatability of the measurement system.
