NIMbox NDL8 - 8 channel leading edge discriminator with programmable NIM or TTL logic

This single slot wide NIM module is a pre-configured version with 4 I/O sub-modules. NDL8 is an 8-channel discriminator with additional 12 programmable I/O ports.Programming the internal FPGA allows to define simple logic functions as AND/OR coincidences and majorities, fan in / fan out etc. between input and outputs but also includes more complex features as timer, counter, and even multi-hit dead-time less Time-to digital converter. All logic functions are programmed into the FPGA via the high speed USB-2 interface.

Using the provided LabView VI library “Toolbox” easy and fast programming of all configurations settings and functions is possible. For more details and customized versions, please see the main NEMbox page.
