Abstract
Method and apparatus for automatic verification of measurement probe functionality and compensation for a wide range of oscillating signal amplitude levels. The invention includes a source of an oscillating signal and a measurement device. A measurement probe is coupled between the measurement device and the source of the oscillating signal, wherein it is desired that the probe is functioning to faithfully transmit the oscillating signal there through. The measurement device is adapted for generating a measurement signal in response to the source of the oscillating signal. Also included is a reference that is based upon actual characteristics of the oscillating signal. A controller is coupled with the measurement device and the reference for making a comparison of the measurement signal to the reference. The controller automatically determines whether the measurement probe is functioning based upon the comparison.
