Claims (1)

[Claims for Utility Model Registration] A device to be measured such as an electronic component or an electronic device, a common contact connected to a test signal generating means, and a plurality of devices connected to each input terminal and short-circuit terminator of the device to be measured. An input consisting of a single-pole multi-throw coaxial switch or a single-pole multi-throw coaxial switch with a built-in terminator, which has a main switching contact and an open auxiliary switching contact, and each switching contact is selectively connected to the common contact. a changeover switch, a common contact, a plurality of main changeover contacts and an open auxiliary changeover contact connected to each output terminal of the object to be measured and a short-circuit terminator, each of the changeover contacts being selectively connected to the common contact; an output selector switch consisting of a single-pole multi-throw coaxial switch or a single-pole multi-throw coaxial switch with a built-in terminator; a bridge that is connected to a common contact of the generating means and the input changeover switch and has a takeout terminal for a return signal from the input changeover switch; and a bridge that is connected to a common contact of the measurement means and the output changeover switch or selectively connects the common contact of the measurement means and the output changeover switch or the takeout terminal. A performance measuring device for a measured object, comprising: an auxiliary changeover switch for switching connection; and a control means for controlling the switching of each of the changeover switches and the contact/separation control of the contact/separation switch.
