Analysis methods of coaxial microcalorimeter data

Abstract

Coaxial Microcalorimeter based on thermoelectric detection is the system used to realize the broadband primary power standard at high frequency (HF) by Istituto Nazionale di Ricerca Metrologica (INRIM). The paper describes the analysis methods applied to the measurement data for correcting the value of the measurand and evaluating the system uncertainty. Data and associated analysis are relevant to the 7 mm and 3.5 mm coaxial insets, covering, therefore, the frequency range 10 MHz – 26.5 GHz.
