Abstract
The present invention relates to a method of measuring the current-voltage characteristics of a DUT by controlling a voltage source and current source of the measurement apparatus by changing a predetermined current value in the current source or a predetermined voltage value in the voltage source in response to an output characteristic. For example, in utilizing a voltage source, the output current limiting value is incremented by a predetermined amount when the current output of a DUT reaches the current limiting value before the voltage output reaches a desired value. The current and voltage outputs of the DUT do not change unless the current limiting value is first incremented. Thus, the output characteristics with a rapid change in the DUT are more accurately measured by controlling the input and output of the DUT.
