Abstract
PURPOSE: To prevent an error decision and also to simplify control over reference IC by providing two reference IC of good quality and by employing a reference signal only when the result of a comparison between two ICs is good.
CONSTITUTION: A signal from input signal generator 1 is applied to IC2 to be tested and two reference ICs 3 and 4. Reference output signals from those two reference ICs 3 and 4 are applied to comparator 5 for a comparing decision and only when the result is good, a comparing decision with the output signal of IC2 to be tested as a reference signal is made by comparator 6 and the comparison result is displayed by display unit 7. Consequently, the risk of an error decision due to faults or abnormality of reference ICs 3 and 4 is prevented and control over reference ICs 3 and 4 is simplified.
