JDPA-1002/4 Digital Pulse Analyzer

Product Description: 

JDPA-1002/4 digital pulse analyzer has built-in digital multi-channel amplitude analysis module (DMCA), constant fraction timing module (CFD), waveform discrimination module (PSD) and other functional modules, which can realize the functions of commonly used nuclear physics measurements such as signal waveform acquisition, energy spectrum acquisition, time identification and particle identification, and meet the signal processing requirements of various nuclear detectors.

The device uses a high-speed ADC with a sampling rate of 1GHz and a resolution of 14 bits and a high-speed, large-capacity DDR3 memory to digitize and store analog signals in real time. The collected data can be quickly transferred to the computer through the USB interface. All signal input channels of the system work independently and support nuclear detector signals with exponential decay characteristics.

The device reserves an external global clock and synchronization interface, and with the clock synchronization unit, it can form a large-scale data acquisition system to synchronously acquire signals from multiple detectors. It has a variety of input and output ports, which can be configured as global triggering, local triggering, and more complex multi-conformity logic. Large-scale FPGA processing unit can expand a variety of digital signal processing algorithms.
