Abstract
PURPOSE: To enable speedy selection as well as shortening much of the measuring time by storing in a wave form memory the output wave form of the IC circuit under test which is a reaction to a single pulse signal and comparing it with the reference output and judging it by a selector.
CONSTITUTION: Signal generator 1 applies a pulse signal such as a single impulse or a step pulse to the IC circuit 2 under test. The output response wave form of the IC circuit 2 corresponding to this pulse signal is stored in the wave form memory 3 and is converted into an S-plane by high speed Fourier converter FFT4, then conveyed to the selector 5. Expected figures for an acceptable IC circuit are stored in the selector 5 as a reference valve and by comparing it with the figures converted from the response wave form of IC circuit 2, judgement is made on whether the IC circuit 2 under test is acceptable or not. Thus, measuring time can be well shortened and high speed selection becomes possible.
