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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
