PROBLEM TO BE SOLVED: To improve measuring efficiency and to decrease testing cost. SOLUTION: A testing-device main body 103 forms and outputs input digital signals 1-L to be imparted to the object for testing. The signals are converted into input analog signals by an input-signal converter 102 on a test heat 101. Furthermore, input-signal selectors (21/11)-(21/NL) switch channels, based on the control of a central controller 104 of the testing-device main body 103, so that the analog signals are outputted from the signals corresponding to a J-number and the arrangement of the object to be tested among output terminals 21-3L of N×L pieces. The M pieces of the output analog signals outputted from the J-pieces of the object to be tested respectively, to which the input analog signals have been inputted from input terminals 51-5M corresponding to the number and the arrangement of the objects to be tested. Output signal selectors (22/11)-(22/NM) switch the channels corresponding to the channels on the side of the testing device main body 103. Outputs signal converters (12/11)-(12/NM) convert the signal into the output digital signal and outputs the signal to the testing device main body 103.
