A signal acquisition device

The invention relates to a signal acquisition device (10) which receives an input signal (12), a physical data (16) and a timing data (20) to generate an output data (24). The signal acquisition device (10) keeps monitoring the input signal (12) for a valid edge. When a valid edge is detected, the signal acquisition device (10) reads the physical data (16) from a physical data processing module (18) and a timing data (20) from a timing module (22) to generate the output data (24) which comprises the new state of the input signal (12), the physical data (16) and the timing data (20). The output data (24) is written to a storage means (11) and also sent out to CPU or any other devices.
