Amptek has a family of products built around its core DP5 digital pulse processing technology, designed for pulse
height spectroscopy. It was originally designed for the detection of ionizing radiation, principally X- ray and gamma-ray
spectroscopy. A generic system, illustrated below, includes a sensor, a.k.a. detector, a charge sensitive preamplifier,
analog prefilter circuitry, an ADC, an FPGA which implements pulse shaping and multichannel analysis, a
communications interface, power supplies, data acquisition and control software, and analysis software.

The core DP5 technology shared by all the systems includes the ADC, the FPGA, the communication
interface, and the data acquisition and control software. All products in the DP5 product family include
nearly the same digital signal processing algorithms, the same communication interfaces (both the primary
serial interfaces and the auxiliary I/O), and use the same data acquisition and control software. The DPPMCA
software package is a complete data acquisition and control application used across the family; Amptek also
offers an SDK for custom software solutions.
The products in the DP5 family differ in the sensor for which they are designed, which leads to changes in
the analog prefilter, power supplies, and form factor. They also differ in their completeness: some of
Amptek's products are "complete" (with detector, preamplifier, DPP, and power supplies), while others
offer only a portion of the functionality for the user to integrate into a complete system.
