The voltage at this output is proportional to the instantaneous vibrational velocity
of the object. The voltage is positive when the object is moving towards the
vibrometer optics.
2 Digital signal output DIGITAL OUT (Triax jack)
At this output the velocity information is available in S / P-DIF format (Sony /
Philips Digital Audio InterFace), e.g. to display the output signal on a PC monitor
using a sound card.
