PROBLEM TO BE SOLVED: To enable correct display of a waveform of a demodulation signal by a single body. SOLUTION: A jitter demodulator 21 which demodulates a jitter component of a digital signal inputted from outside, a jitter amount calculator 22 which calculates an amplitude value of a demodulated signal J outputted from the jitter demodulator 21, an interpolator 23 which performs period measurement for the demodulated signal J outputted from the jitter demodulator 21 and performs interpolation processing with magnification according to the measured period, a display unit 25, and a display control part 24 which makes the display unit display a calculated value of the jitter amount calculator 22 and the waveform of the demodulated signal interpolated by the interpolator 23, are provided in a single case body.
