Patent ID: 7375534

Claim:
A method for measuring high-frequency characteristics of an electronic device, the method comprising the steps of: preparing a transmission line whose electrical characteristics per unit length are known, the transmission line including a plurality of signal conductors disposed with a space therebetween, and at least one ground conductor; connecting the signal conductors and the ground conductor to associated measurement ports of a measuring device; measuring, at least three points in the longitudinal direction of each signal conductor, an electrical characteristic in a connection state where each signal conductor is connected to the ground conductor; measuring electrical characteristics in a through state between the signal conductors; obtaining error factors of a measurement system including the transmission line on the basis of measured values in the connection state, measured values in the through state, and the electrical characteristics of the transmission line; connecting the electronic device to be measured between the signal conductors or among the signal conductors and the ground conductor and measuring electrical characteristics; and removing the error factors of the measurement system from measured values of the electronic device to be measured and obtaining true values of the electrical characteristics of the electronic device to be measured.
