1. A measurement apparatus comprising:

  • a sensor having at least one emitter and an associated detector configured to attach to a tissue site, said detector providing a detector signal responsive to the intensity of energy from said emitter after it has passed through said tissue site;

    a first pulse oximeter in communication with said detector and configured to compute an oxygen saturation measurement based on said detector signal;

    a waveform generator responsive to said oxygen saturation measurement to generate at least one generated waveform based on said oxygen saturation measurement, wherein said at least one waveform is synthesized so that a second pulse oximeter receiving said waveform would calculate an oxygen saturation value generally equivalent to said oxygen saturation measurement.
