All Amptek x-ray detector elements are available in either the XR100 or X-123 configuration. The XR100 configuration includes the detector and preamplifier only and must be paired with the PX4 digital pulse processor, MCA, and power supply to be a complete system. The X-123 includes the digital pulse processor, MCA, and power supply and is a complete system. The XR100/PX4 combination is the best performing and most flexible and is designed for laboratory use. The PX4 can be used with other detectors and offers software control of all detector power supplies. The X-123 configuration is designed for OEM and custom applications where size and portability are considerations. The X-123 is designed to be small and low power and therefore has fixed power supplies set to the requirements of the detector.
