Microcalorimeter Evaluation with Three Different Sensor Types
Data for a paper to be submitted to CPEM2026. Abstract:
At many National Metrology Institutes (NMIs),
microcalorimeters serve as the primary standard for traceable
power measurements. Usually, microcalorimeters are designed
to be used with a specific type of rf power sensor. Modern
twin-load microcalorimeter designs can accommodate multiple
power sensor technologies. However, it is unclear how to evaluate
a microcalorimeter with multiple types of sensors. The largest
source of uncertainty for measurements in the microcalorimeter
is the correction factor, which quantifies heat absorbed in the
transmission line that carries rf power to the device under test
(DUT). In this paper, we present a model of the correction factor,
and test it through measurements with three types of rf power
sensors. These preliminary measurements are part of an effort to
evaluate a newly-built microcalorimeter with 2.4 mm connectors.
