Abstract

In RF metrology, noise power measurements consist of intercomparisons between the output noise powers of unknown noise sources and noise standards. With respect to the traceability of the assigned values of noise power, the estimation of uncertainties of measurement plays a decisive role. The evaluation of uncertainties is discussed in relation to the appropriate recommendations of the Comite International des Poids et Mesures (CIPM) and respective guidelines of the Western European Calibration Cooperation (WECC). The authors give specific advice for the treatment of measurement uncertainties in the RF noise power measuring field in order to make the information more readily applicable
