Uncertainty Estimation of Probe Calibrations Using a Power Flux Density System of (18~26.5) GHz

Abstract:

A method for the uncertainty estimation of probe calibrations using the power flux density (PFD) system of (18~26.5) GHz recently developed at the National Institute of Metrology, China is presented. A measurement model is developed first, and then the sources of uncertainty and the corresponding evaluation procedures are explained. The method is used to estimate the uncertainty of the calibration factor of a FP7050 probe at 18 GHz obtained by the PFD system. The good agreement between the calibration results from two PFD systems validates the method.
