FAST ComTec MCS6A and P788x Series,
Ultra-Fast Multi-Hit Multiscaler/Time-Of-Flight (TOF) Modules


Designed to sort incoming digital counts received at the STOP inputs, relative to the signal at the START input (reference) for applications requiring time-resolved single event counting. These boards feature ZERO interbin dead time (and zero end of sweep deadtime in an internal trigger mode) and read out only time bins that contain an actual count, thus offering faster sweep repetition rates.  Especially for those applications with relatively sparse data points, these devices have effectively increased the upper limit for single-ion or single-photon time-resolved counting applications.

The MCS6A is the latest, highest-performance multiscaler in this line up and features multiple input configurations, 100 ps time-bin resolution, 5GHz input burst count rate (10GHz state changes), ~18MHz sustained count rate, a 2B FIFO front end, 10mV input sensistivity with rising/falling/both edge discrimination from +/-1V, and a dual USB2.0 interface. One USB 2.0 interface port is required for operation, however, the maximum possible transfer data rates can only be achieved with the use of two USB2.0 ports.

The PCI-slot based cards require a motherboard/case combination that will accommodate full length (~13.7") PC expansion cards. A maximum of four cards may be operated in a single host PC. See the Host PC Selection Guide  for details regarding computer compatibility of these PCI cards, not all PC's are compatible.

The devices are compatible with both 32- and 64-bit versions of the Windows Operating System. Optional software to operate under a LINUX operating system is available. And all devices include the appropriate input cables and MCDWIN/MPANT operating software. See individual data sheets for more details and specific features.
