The PhotoniQ model MCPC682 is a complete, off-the-shelf, high speed, 64 channel pulse counting system for PMTs, silicon photomultipliers (SiPM) and APDs. Implemented as a stand-alone laboratory instrument with a PC interface, the MCPC682 is used for discrimination, counting, and data acquisition (DAQ) of single pulse events across 64 independent counting channels. Its front end design permits direct connection to most PMTs and SiPMs without the need for a preamplifier. Flexible intelligent triggering allows the unit to reliably acquire count data using one of several sophisticated triggering techniques. The MCPC682 is fully configurable through the PC via its USB 2.0 port using an included graphical user interface. Continuous high speed data transfers to the PC are also handled through this port. Additionally, a LabView™ generated DLL is provided for users who wish to write their own applications that interface directly to the unit. MCPC682 64通道光子計數系統 特點:
