NIMbox NDL8
NDL8 – 8 channel LE discriminator with 10 programmable NIM or TTL I/O ports and 2 TTL I/O ports
This single slot wide NIM module is a pre-configured NIMbox version with 2 x SU703 and 2 x SU704 sub-modules. NDL8 is a 8 channel leading edge discriminator with additional 10 programmable NIM or TTL I/O ports and 2 TTL I/O ports.
Programming the internal FPGA allows to set-up the discriminator channels but also to define logic functions for the 12 I/O ports. This includes AND/OR coincidences and majorities fan in / fan out etc. but also include 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.

- Programmable hysteresis ( 0 to 60 mV, 12 bit)
- 5 programmable LED/s
- SU704: 5 channel NIM or TTL Input / Output
- 50 Ohm, Lemo connectors
- NIM or TTL for each channel jumper selectable
- Output -16 mA (NIM) or 0 – 3.3V (TTL)
