Test apparatus with voltage margin test
摘要:
A pattern generator generates a pattern signal which represents a test signal to be supplied to a DUT. A driver generates a test signal having a level that corresponds to the pattern signal, and outputs the test signal thus generated to the DUT. A voltage modulator changes, in a predetermined voltage range, the voltage level of the test signal output from the driver DR.
