The Pixie-Net is a 4-channel digital pulse processor for radiation detectors in desktop format with integrated Linux operating system.

  • Supports coincidence gated acquisition, pulse shape analysis, and constant fraction timing
  • Compact desktop or OEM card formats
  • Designed as cost-effective entry-level version of the Pixie pulse processor series.
SKU: PIXIE-NET Categories: , ,

The Pixie-Net integrates a Linux platform with real time digital pulse processing. Data acquisition can be managed through local Linux C programs, webpages, or web API functions for control interfaces running on remote computers. C programs are kept simple and can be compiled on the Pixie-Net itself to facilitate customizations by users.

The pulse processing is equivalent to the Pixie Hybrid, but without the need for PXI infrastructure, list mode data storage on local SD card, and with lower throughput. Configurable signal processing characteristics give you flexibility in detector choice. Coincidence and pulse shape analysis logic can be applied in real time to reduce the amount of data that needs to be transferred to final storage.

Multiple units can be operated synchronously through network time synchronization (IEEE 1588 PTP) to a precision in the tens of nanoseconds without the need for additional clock and trigger cabling. Higher precision is supported in the Pixie-Net XL with White Rabbit.
