置。[Claim for Utility Model Registration] In a passive probe device that has a contact that can make contact with a signal observation point of a circuit to be measured and is connected to an input terminal of a signal measuring device, the input resistance is increased depending on the target to be measured. A probe head with a switch for switching between a resistance system and a low resistance system, a coaxial cable with a characteristic impedance equal to the resistance value of the low resistance system and connected to the probe head at one end, and a correction according to the input resistance selection. A passive probe device comprising: a changeover switch for switching elements; and a correction circuit connected to the other end of a coaxial cable.
