DPP4553 - OEM Digital Pulse Processor Board for X-ray Spectroscopy
The DPP-4553 is a high-performance and low power digital pulse processor board developed to be easily integrated in OEM systems. It integrates state-of-the-art performance in a very compact form factor, enabling high count rate application (up to OCR=1.8Mcsp @ICR=5Mcps) as well as low element detection down to Beryllium and Lithium.
Main Features

- Physical Size: 10 cm x 5.8 cm
- Preamplifier compatibility: continuous mode or pulsed-reset
- Pulse filtering: fixed trapezoidal (minimum peaking time: 32 ns)
- Multi-channel: daisy chain connection for synchronous acquisition
- Special functionalities: Mapping Mode, List Mode, Gating mode
Applications
- X-ray fluorescence (XRF)
- In-line scanners
- Defect inspection or quality control
- Handheld instrumentation
