Abstract

PURPOSE:To enable the independent controlling of rise time and fall time of the surge voltage against a sample by a method wherein charge and discharge resistors to be connected to the base of a transistor forming an emitter follower connection are selectively connected by a switch. CONSTITUTION:A peak value instituting direct current source W is connected to a sample X to be measured like an electronic apparatus, etc., through a transistor T forming an emitter follower connection. A capacitor C2 is connected between the base of the transistor T and the earth, and a voltage rise time instituting charge resistor R2 and a voltage fall time instituting discharge resistor R3 are connected to the base of the transistor T through a switch S. The switch S is made to close to the R2 side to make the rising of voltage, and then is made to close to the R3 side to make the falling of voltage. Therefore the rising time and the falling time of voltage can be instituted notwithstanding the impedance of the sample X to enable the highly precise controlling.
