Abstract:
1. 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 and a ground conductor; connecting two ends of the transmission line to associated measurement ports of a measuring device; measuring, at least three points in the longitudinal direction of the transmission line, electrical characteristics 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; shunt-connecting the electronic device to be measured to the transmission line and measuring electrical characteristics; and removing the error factors of the measurement system from measured values of the electronic device to be measured and thereby obtaining true values of the electrical characteristics of the electronic device to be measured.
