SIGNAL QUALITY EVALUATION DEVICE AND EVALUATION METHOD

Japanese Patent JP2014169914

A

PROBLEM TO BE SOLVED: To notify an evaluator of a deviation of a measurement value from a normal range when the measurement value in the midst of averaging deviates from the normal range in a signal quality evaluation device performing appropriateness determination to a result in which the measurement value calculated from waveform data on a signal of an evaluation object is averaged, and to enable an analysis of the waveform data in this case.SOLUTION: A signal quality evaluation device is configured to: acquire waveform data on a signal Sx of an evaluation object, and sequentially update the acquired waveform data, and store the updated waveform data in a waveform data memory 22; calculate a measurement value as to a predetermined measurement item with respect to the newly stored waveform data; perform an averaging process to the calculated measurement value by a preliminarily set number of averaging times, and determine whether each of calculated measurement values falls within a first normal range, and whether a final measurement result obtained by the averaging process falls within a second normal range; store the waveform data serving as a base of the measurement value determined not to fall within the first normal range in an NG waveform data memory 28; and perform a detail analysis process to the stored waveform data.
