The Amptek PX5 interfaces between (1) an X-ray and gamma-ray detector with its preamplifier and (2) a computer running data acquisition and control software. Designed principally to support Amptek s XR100 series of SDD, Si-PIN, and CdTe detectors, it can be used with many other radiation detectors and preamplifiers, including HPGe detectors. It is compatible with both reset and feedback preamplifiers of either polarity. The PX5 includes (1) a high performance digital pulse processor (replacing a conventional shaping amplifier), (2) a multichannel analyzer, and (3) both low and high voltage power supplies (±10).

The PX5 offers several advantages over traditional systems, including improved performance (very high resolution, reduced ballistic deficit, higher throughput, and enhanced stability), many more configuration options to optimize the system, and many communications and output options. The PX5 is based on Amptek’s latest generation of digital pulse processing technology, also used in the DP5 family of products.

The PX5 is compatible with both 32 and 64 bit operating systems, including Windows 7.
