【Abstract】 Based on analyzing the sources of measurement errors, the correction methods of the errors are introduced and error models of two port calibration are provided. The systematic errors can be determined by measuring known calibration standards. Moreover, if there are some errors in known calibration standards , the methods how to compute systematic errors are studied. According to the measuring results of property of 50 Ω impedance , the availability of the methods is proved.更多还原
