发明名称 Detection apparatus and test apparatus
摘要 A detection apparatus is provided. The detection apparatus includes; a multi-strobe generating section that generates a plurality of strobe signals with phases different from one another; a plurality of acquiring sections each of which acquires a signal value of a signal under measurement at a timing of each of the plurality of strobe signals; a plurality of changing point detecting sections that detect a fact that there is a changing point of the signal under measurement between two adjacent strobe signals when two signal values which are acquired in accordance with the two adjacent strobe signals are different from one another; a mask setting section that sets the changing point detecting section to be enabled among the plurality of changing point detecting sections; and a changing timing output section that outputs a changing timing of the signal under measurement based on an output of the enabled changing point detecting section.
