摘要

This paper describes the bilateral comparison carried out by two National Metrology Institutes, NMC from Singapore and INRIM from Italy. The subject of the comparison concerns the calibration of a new type of coaxial power sensors fitted with type N (up to 18 GHz) and 3.5 mm (up to 26.5 GHz) connector. This is the first international comparison of this kind in which the transfer standards are based on indirect heating thermocouples. Results show that the introduction of this type of transfer standard and the update of the measurement techniques of both institutes allowed a general reduction of the uncertainty with respect to that declared in the last Key Comparison in the field.
