Abstract
PURPOSE: To shorten time for obtaining test patterns, time necessary for copy, by writing expected patterns in a pattern memory without erasing patterns applied at that time.
CONSTITUTION: When applied patterns are applied to a device to be tested 13 from a pattern memory 11, either of the two of patterns applied at that time and the output of the device to be tested is selected by output pin appointed data every each bit, test pattrns are gained at a stroke and the patterns are memorized to the pattern memory 11. Thus, all applied patterns are successively sent to the device to be tested 13 for excellent articles, and test patterns containing applied patterns and expected patterns are automatically obtained if said supply is completed.
