- Abstract:
- The power is the most important electromagnetic quantity from the metrological point of view, and for this reason the calibration techniques of high frequency power meters require a specific attention. Literature still refers to power meters of bolometer type, instruments that are mainly used almost only in the primary laboratories. Definitions, procedures, and calibration techniques elaborated for this instrument type must be adjusted before being applied to actual power meters, which work on different principles. Otherwise, inconsistent calibration results may be produced. This paper is aimed to ease the work of the laboratories that perform power meter calibrations from dc to 50 GHz, by elaborating on some technical aspect not well considered in the specialized literature.
