Abstract:\n\nAt many National Metrology Institutes (NMIs),\nmicrocalorimeters serve as the primary standard for traceable\npower measurements. Usually, microcalorimeters are designed\nto be used with a specific type of rf power sensor. Modern\ntwin-load microcalorimeter designs can accommodate multiple\npower sensor technologies. However, it is unclear how to evaluate\na microcalorimeter with multiple types of sensors. The largest\nsource of uncertainty for measurements in the microcalorimeter\nis the correction factor, which quantifies heat absorbed in the\ntransmission line that carries rf power to the device under test\n(DUT). In this paper, we present a model of the correction factor,\nand test it through measurements with three types of rf power\nsensors. These preliminary measurements are part of an effort to\nevaluate a newly-built microcalorimeter with 2.4 mm connectors.", "distribution": [{"description": "A readme file for this data set.", "downloadURL": "https://data.nist.gov/od/ds/mds2-4112/README.txt", "mediaType": "text/plain", "title": "README"}, {"description": "Thermal coefficient k_1 of a 2.4 mm calorimeter, estimated from measurements a specific commercial type of  of thermoelectric rf sensor (denoted TE1 in the paper).
