PROBLEM TO BE SOLVED: To inhibit the device cost from increasing and to intend to reduce the test time. SOLUTION: The signal process device comprises: a first occurrence point of time detection means for outputting a first occurrence point of time signal representing the occurrence point of time of a first signal by inputting the first signal; the second occurrence point of time detection means for outputting the second occurrence point of time signal representing the occurrence point of time of the second signal by inputting the second signal asynchronous to the first signal; a selection means having a first mode for selectively outputting the first signal and the first occurrence point of time signal, and the second mode for selectively outputting the second signal and the second occurrence point of time signal by inputting the first signal and the first occurrence point of time signal, and the second signal and the second occurrence point of time signal.
