Digital Pulse Processor DP5

The Amptek DP5 is a state of the art, high performance, low power digital pulse processor. It digitizes the preamplifier output signals, replacing both the shaping amplifier and MCA in a traditional, analog spectroscopy system. The DP5 offers several clear advantages over traditional systems, including improved performance (very high resolution, reduced ballistic deficit, higher throughput, and enhanced stability), enhanced flexibility, low power consumption, small size, and low cost.

The DP5 implements the pulse processing using dedicated circuitry. It includes an 8051 compatible microcontroller for controlling the unit. Communication interfaces include RS232, USB, and Ethernet. Several general purpose I/O lines are also available. The DP5 is suitable for OEMs and for laboratory users who need custom capabilities and are familiar with electronics.
