Multichannel TDC provides 81-ps timing resolution
Test & Measurement World Staff - August 23, 2012
The id800 TDC (time-to-digital converter) from Swiss manufacturer ID Quantique is used to transfer the time tags of registered events with picosecond precision and at high rates to a computer. It registers incoming signal events on eight independent channels, records their exact time and channel number with 81-ps timing resolution (bin size), and communicates these to a PC via its USB 2.0 interface. Additionally, the instrument can count single and multiple-channel coincidence events.
Applications for the time-to-digital converter include time-correlated single-photon counting, LIDAR, correlation measurement, quantum optics, optical measurements, precision time measurement, and fluorescence microscopy. A graphical user interface is supplied with the id800 for Windows and Linux, along with software examples for C/C++ and LabView. The converter, which is 250×100×300 mm, operates from a power supply of 110 VAC to 230 VAC and has BNC input connectors. Input levels are LVTTL with 5-V tolerance.
The id800 time-to-digital converter is scheduled for release Q3, 2012.
