NIMbox NAD4 - 4 channel 100 MHz flash ADC with 8 programmable TTL I/O ports

This single slot wide NIM module is a pre-configured version with 4 x SU701 sub-modules. NAD4 is an 4 channel 14-bit 100MHz flash ADC with FIFO and with additional 8 programmable TTL I/O ports.  NAD4 can be used as digitizer / oscilloscope.

Programming the internal FPGA allows to set-up the ADC channels and their data read out but also to define logic functions for the 8TTL I/O ports. This includes AND/OR coincidences and majorities, fan in / fan out etc. 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.
