Abstract: PURPOSE:To measure variation in characteristic due to load variation instantly and to shorten a measurement time by measuring a characteristic curve dynamically. CONSTITUTION:A counter part 2 increases a control signal continuously and counts a clock generated by a clock generation part 1. Then the output of an ultrasonic wave power source is brought under digital control 12 with the count output value of the counter part 12 to vary the amplitude of the ultrasonic wave output linearly. Then a zero peak detector 7 detects the ultrasonic wave output, i.e. electric power, current and voltage after the digital control 12 and linearizes the ultrasonic wave output to obtain a Y-axial signal. For an X-axial sweep signal, the counted output value of the counter part 2 is converted by a D/A converter 4 into an analog signal to generate a rectangular wave signal. Then the X-axial and Y-axial signals are inputted to an orthogonal coordinate measuring instrument such as a synchroscope and an X-Y recorder to measure the characteristic curve of an ultrasonic wave automatically.
