摘要

Method for calibrating a (10) N terminal microwave measurement network includes a step of measuring a network parameter values ​​loading device (43), the accuracy of this method, knowledge of the parasitic impedance (43) load devices I depend on. In accordance with the present invention, the accuracy of the method is improved by determining at least approximately the parasitic impedance (43) the load device. In one embodiment, this is accomplished by measuring the network parameter values ​​(44) auxiliary open device having a parasitic impedance substantially equal to the load devices (43). Furthermore, the accuracy of the method is improved by measuring the network parameter values ​​(45) auxiliary short device having a parasitic impedance substantially equal to the load device (43). It can also be used to de-embedding a device under test similar principles. Disclosed (43), the auxiliary open device short auxiliary device (44) also (45) load device having a parasitic impedance are substantially equal.
