There is provided a calibration apparatus for calibrating a jitter measuring circuit for outputting a jitter measuring signal corresponding to a value of jitter contained in an input signal, having a signal inputting section for sequentially inputting the first input signal having first period and the second input signal having second period to the jitter measuring circuit and a gain calculating section for calculating a gain in the jitter measuring circuit based on the jitter measuring signals to be outputted out of the jitter measuring circuit respectively with respect to the first and second input signals.
