Division of Electricity and Quantum Metrology, National Institute of Metrology, Beijing 100013, ChinaAbstract:Measurement theory and method of high-frequency characteristic of four-terminal-pair standard resistance are studied in order to resolve the problem that resistance value marked in the DC is used in the high-frequency range. Based on capacitance standard in the extending frequency range acting as value standard and the measurement principle of four-terminal-pair impedance, measurement principle is performed to measure the high-frequency characteristic of four-terminal-pair resistance making use of an open-short-load （OSL） calibration technique. Measurement method is that a resistance is calibrated by several capacitance standards by keeping measurement instrument＇ s measurement range invariable. It can eliminate the nonlinearity error of the measurement instrument. The principle and method can reduce measurement results uncertainty and provide theory foundation for four-terminal-pair resistance＇ s application in the high-frequency range.[著者文摘]
