Abstract

PURPOSE: To make synthetic tests of a complex input by making a decision on quality by using an integral value relating to the time of a difference between the output amplitude of a standard element and that of an element to be tested.
CONSTITUTION: When a test signal from test signal generator 1 is applied to standard element SD (or standard circuit) 2 and tested element DUT (or tested circuit) 3 at the same time, the output of differential amplifier 4 in proportion to the abslolute value of a difference between outputs of SD2 and DUT3 is inputted to voltage- current converter 5. The output of voltage-current converter 5 is integrated by integrator 6 as long as the period of the test signal and this integrator 6 outputs the level of the difference between outputs of SD2 and DUT3 and a signal in proportion to area formed by the time; and this output level is compared with the reference level from reference level generator 7 by comparator 8 to make a decision on the quality.
