Patent ID: 7439748

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 signal conductor whose first end is an open end, and a ground conductor; connecting a second end of the signal conductor and the ground conductor to associated measurement ports of a measuring device; measuring, at at least three points in the longitudinal direction of the signal conductor, an electrical characteristic in a connection state where the signal conductor is connected to the ground conductor; obtaining error factors of a measurement system including the transmission line on the basis of measured values in the connection state and the electrical characteristics of the transmission line; connecting the electronic device to be measured between the open end of the signal conductor and the ground conductor and measuring an electrical characteristic; and removing the error factors of the measurement system from a measured value of the electronic device to be measured and obtaining a true value of the electrical characteristic of the electronic device to be measured.
