A system, computer program product and method of obtaining a performance parameter associated with a sensor, such as an accelerometer, is provided. The method includes applying an acceleration to the accelerometer and a first frequency to obtain a sensitivity of the accelerometer at the first frequency. A first self-test is performed on the accelerometer. The first self-test includes stimulating the accelerometer with a first self-test stimulation signal encoded with the first frequency, such that the accelerometer outputs a first signal. A self-test equivalent acceleration is then determined based, at least in part, on the first signal and the accelerometer sensitivity at the first frequency. A second self-test is performed on the accelerometer. The second self-test includes stimulating the accelerometer with a second self-test stimulation signal encoded with the second frequency, such that the accelerometer outputs a second signal. A parameter of the accelerometer is determined at the second frequency based, at least in part, on the second signal and the self-test equivalent acceleration. The parameter may be sensitivity of the accelerometer at the second frequency.
