PicoQuant’s latest multichannel event timer, the MultiHarp 160, is a plug-and-play time tagger and Time-Correlated Single Photon Counting (TCSPC) unit. It is optimised for applications requiring up to 64 timing channels with a time resolution of 5 ps and dead time of less than 650 ps. The MultiHarp 160’s number of synchronised input channels can be scaled from 16 to 64. A common synchronisation channel, supporting sync rates of up to 1.2 GHz for periodic signals, is available as timing reference for all channels. Time tags from all input channels are combined into a single data stream that is accessible via an USB 3.0 interface. The data stream is also accessible to external FPGA boards via a dedicated interface, enabling great flexibility in tailoring the way how data is preprocessed to the specific needs of an application. Furthermore, the MultiHarp 160 supports synchronisation of multiple devices via White Rabbit timing networks, GPS, PPS or external references.
