1. An oxygenated tissue simulator adapted to test a pulse oximeter with one or more interrogating light signals, the interrogating light signals comprising a red light signal and an infrared light signal, the tissue simulator comprising:

  • one or more detectors adapted to convert the red light signal and infrared light signal of the pulse oximeter into at least one electrical signal;

    one or more light sources adapted to convert the at least one electrical signal into at least one carrier light signal;

    means for modulating the at least one carrier light signal to simulate oxygenated tissue; and

    means for transmitting the at least one modulated carrier light signal to the pulse oximeter.
