Measurement data synchronization method, testing method, and non-transitory computer-readable medium storing computer program

A test method for evaluating a performance of an test object by processing time series data outputted from a plurality of measuring instruments by a computer, the test method comprising:

• acquiring reference data, which is time series data outputted from each measuring instrument, when a reference signal including a steady section and a rising section is simultaneously inputted to a reference signal channel of each of the plurality of measuring instruments, and measurement data, which is time series data outputted from each measuring instrument, when a signal correlated with a state of the test object is inputted to each measuring channel of the plurality of measuring instruments;
• generating a plurality of pieces of filtered data by performing median filtering processing for extracting a median value within a predetermined time width on each of a plurality of pieces of the reference data;
• acquiring rising timing information from each of the plurality of pieces of filtered data;
• synchronizing a plurality of pieces of the measurement data based on a plurality of pieces of the rising timing information;
• and
• evaluating a performance of the test object based on the plurality of pieces of synchronized measurement data.
