NEMbox / NIMbox Programmable NIM Module

NEMbox (Nuclear Electronics Miniature Box) is a programmable Logic / DAQ module, powered either in a NIM crate (NIMbox version) or with a commercial 6V output AC/DC transformer ("Desk" version). It is well suited for scientific and educational purposes.
NEMbox and NIMbox consist of a FPGA main and carrier board and up to 4 I/O Submodules, VHDL modules as well as interface software featuring "LogicPool", a very new and unique way for the user to build up his specific setup by using prebuilt functional modules and to wire them internally for his application. A user defined internal wiring configuration can be saved on an EPROM chip so that the module does not need to be reprogrammed in case of power failure or system reset. All communication with the module as well as programming is done via a USB-2 interface.

Being able to work as multiple coincidence, fan in / fan out, splitter, logic, discriminator, ADC, TDC, etc., NEMbox/NIMbox finds many applications in trigger logic and data acquisition, and allows to cut costs because one single unit can replace the functionality of several non programmable NIM modules.

Software Features

Labview Tool Box / example.:

NEMbox / NIMbox can be programmed with LabView VIs. Above example: two discriminators are put in coincidence and a NIM veto signal is present too. A gate is then generated. Inputs left, output right. The logic can be saved in the internal EEPROM.
