In a method for testing for probe calibration, a square-wave signal is applied to a probe and a cyclic probe output signal resulting therefrom is compared to a reference level at a plurality of points along one cycle of the output signal. The reference signal is iteratively increased or decreased until it is less than or greater than a minimum or maximum peak magnitude of the probe output signal by a small amount. The probe is then determined to be calibrated according whether the magnitude of the output signal at each point is greater than or less than the reference level.
