The arrival times of the TTL incoming pulses are stored digitally and can be transferred to a PC using the USB 2.0. The quTAU not only counts and stores individual events but coincidences between two or more channels as well. The coincidence time window can be easily set by the user. These features have been designed with applications such as quantum optics, fluorescence microscopy and high-energy physics in mind.
The system comes with example software for LabViewTM and C/C++ and can be operated on Windows and Linux PCs.
