PROBLEM TO BE SOLVED: To realize a test system which suppresses degradation of accuracy in a temporal measurement of an object to be tested, having a high-voltage output. SOLUTION: The test system which is realized by improving a system used for testing the object to be tested outputting a high-voltage pulse signal, comprises a determining section which inputs the pulse signal of the object to be tested and determines its high level and low level, based on high-level and low-level threshold voltages; a transformer into which the determination result of the determining section is input; and a time-measuring section which inputs the output of this transformer and carries out the temporal measurement by using a low-voltage signal.
