PROBLEM TO BE SOLVED: To provide a technique whereby a data signal acquisition device for acquiring data signals can adequately acquire data signals depending on the timing of the data signals. SOLUTION: For every group of settings comprising a plurality of combinations of settings that are the same as to coarse settings made by a coarse tuning part for tuning the timing of acquiring the data signals at relatively large time intervals but are different in fine settings made by a fine-tuning part for tuning the timing of acquiring the data signals at relatively small time intervals, a determination is made as to whether or not the acquisition of the data signals has been achieved normally. For every group of settings, the number of successes, i.e., the number of successful combinations of settings for which data acquisition has been determined to be normal, is calculated. From among the successful combinations of settings included in the largest group of settings for which the number of successes is greatest, combinations of control settings for defining coarse settings and fine settings are adopted.
