Hardware simulator for photon correlation spectroscopy”, Rev. Sci. Instrum., 74, (2003) 4273-4279

A hardware simulator, used for testing digital correlators in photon correlation spectroscopy, was described. An instrument capable of delivering a continuous stream of transistor-transistor logic pulses over one or more channels was also realized. The photodetector defects were simulated and their elimination by cross correlation techniques was checked.
