The Precise Measurement of RF Power and Voltage Using Coaxial Calorimeters and Microcalorimeters

Automated calorimeters and microcalorimeters used by the CSIRO Division of Applied Physics as primary standards of radio frequency power and voltage and for measuring the effective efficiency of bolometer mounts are described. Methods for evaluating corrections from computer models of the thermal and electrical circuits and results of measurements and intercomparisons are presented.
