Summary:A system and method are disclosed for calibrating non-linear behavior using attenuated stimuli and responses which allows for calibration with unknown stimulus and less expensive sources and receivers. The device under test is stimulated with a signal and then an attenuated version of the same signal, so that non-linear differences between responses can be attributed to the device rather than the signal source. Alternatively, or in conjunction with attenuation of the stimulus, the output of the device at different response amplitudes can be selectively attenuated such that the receiver measures approximately the same amplitude. This allows non-linear differences between measurements to be attributed to the device rather than the receiver. Two or more different signal sources can also be used, where responses are measured for each signal individually and then for at least one linear combination of signals.
