26.5 Linearity of the amplitude axis
Adjust the level of the calibration unit so that the peak is at the top of the amplitude axis (0th div), and
regard the point set at that time as the reference. Gradually lower the output, starting from the reference,
and measure the amplitude value of 2650/2652/2658.
