Abstract
PURPOSE:To shorten the testing time and simplify the controlling operation therefor, by providing a digital signal processor for calculating signals at high speeds by the control of a control unit, a D/A converter and a voltage-current amplifier so as to generate a desired voltage waveform. CONSTITUTION:A control unit 1 selects, feeds necessary processing programs for the calculation, and data required for the calculation such as a constant, a sampling time, etc., to a digital signal processor DSP2, so that the start of the calculation is instructed by the control unit 1 to the DSP2. In response to the instruction, the DSP2 starts the calculation at high speeds in accordance with the calculation programs, and feeds every sampling time digital signals which are the results of the calculation to a D/A converter 3. The digital signals are converted into analog signals in the D/A converter 3, and then amplified in a voltage-current amplifier 4, so that a desired voltage waveform is added to an IC to be tested. Accordingly, without any external circuit or apparatus, a desired voltage waveform can be generated, and therefore the testing of the IC can be carried out in a reduced time, with simplified controlling arrangement therefor.
