ABSTRACT:
A time shifting signal acquisition probe system has a signal acquisition probe having a memory containing a time delay constant representative of the propagation time delay of an electrical signal passing through the signal acquisition probe. A measurement test instrument receives the electrical signal from the signal acquisition probe and generating digital samples of the electrical signal in an acquisition system in response to a trigger signal and producing a waveform record. A communications bus coupled between the signal acquisition probe and the measurement test instrument couples the signal acquisition probe time delay constant from the signal acquisition probe to the measurement test instrument wherein processing circuitry in the measurement test instrument time shifts the waveform record of the electrical signal relative to the trigger signal by the amount of the signal acquisition probe time delay constant.
