DSP microcontroller DP5G

The Amptek DP5G is a state-of-the-art, high performance, low power digital pulse processor designed for use in scintillation spectroscopy systems. Connected to the anode of a PMT, it includes a charge sensitive preamplifier and a digital pulse processor, which replaces both the shaping amplifier and the MCA in a traditional nuclear spectroscopy system. The DP5G offers several advantages over traditional systems, including higher performance, enhanced flexibility, small size, and low cost. The DP5G is one component in a complete gamma-ray spectrometer, shown in the diagram below. The DP5G includes only the core signal processing functions. A complete system must also include a detector module (scintillator, PMT, HV supply, tube base) and interface circuitry with power supplies and connectors for the serial connection. Amptek can provide an OEM user with the DP5G alone, or can provide it with a PCG interface module, or can provide a complete system, including the detector module. The complete system is a separate Amptek product, the Gamma-Rad5. The DP5G represents the latest generation in digital pulse processing. The DP5G is a variant of the DP5, optimized for scintillation readout. The DP5 technology includes faster peaking times, improve pile-up rejection and pulse shape discrmination, better dead time correction, additional features such as a “List Mode,” and enhanced interfaces.
