High precision NIM counter/FPGA counting module

The high-precision NIM counter/FPGA counting module is a counting module developed based on FPGA (Field Programmable Gate Array) and microcontroller technology. This plugin is compatible with 5UNIM chassis and consists of 2 unit width NIM plugins. By adjusting the threshold voltage through a knob, pulse counting can be achieved for two channels. High precision NIM counters are mainly used in various nuclear science applications, providing customers with highly reliable and easy-to-use nuclear pulse technology solutions. The NIM module structure used can be compactly integrated into user experimental platforms or instrument systems, and supports GPIB communication.
