Abstract: PURPOSE:To obtain various short-circuit reflection waves for a withstanding voltage testing voltage by varying the pulse width, cable length and power source voltage utilizing a short-circuit reflection which is produced when a pulse is applied to a constant impedance cable. CONSTITUTION:In a circuit 1 to be tested, one end of a cable of a characteristic impedance Z0=100OMEGA, for example, is connected to a connection point to be tested while the other end thereof is connected to an output terminal of a constant voltage power source 5 whose output voltage can be varied. Consequently, the falling of a signal 21 applied to the connection point 31 is inverted to a rising with a driving circuit 3a so that a short-circuit reflection is caused with a cable 4 with a length l to produce a sharp pulse. On the other hand, the voltage Vb of the power source 5 sets a working point P on an output characteristic curve a of the driving circuit 3a. Then, Vp is measured by changing the Vb. This provides an input withstanding voltage on a slant line of a characteristic impedance Z0 of the cable 4 from the point P on the output characteristic curve (a) as parameter of the pulse width.
