Thermoelectric Sensors as Microcalorimeter Load
L. Brunetti, L. Oberto, E. Vremera
Thermoelectric power sensors can now be used as transfer standards, instead of bolometers, in the microcalorimeter technique. This alternative has the technical advantages to be le…
On Coaxial Microcalorimeter Calibration
L. Brunetti, L. Oberto
Primary power standards in the microwave domain are realized using a calorimetric technique, usually identified with the used measurement system, i.e., the microcalorimeter. It is…
Improvement of primary power standard through international comparison feedback
Luciano Brunetti, Luca Oberto, Marco Sellone
The high frequency primary power standard is univocally realized by means of a coaxial microcalorimeter, at least up to 40 GHz. The coaxial microcalorimeter is a broadband measurem…
