Pixie-Net
The Pixie-Net is a multi-channel digital spectrometer for radiation detectors in desktop format with integrated processor, networking and USB resources. No PC is required for operation. Advantages include:
- Compact desktop or OEM card formats
- Embedded processor with Linux OS, – no PC required
- Web Server interface for remote operation
- High Performance specification: 250 MSPS at 12-bit resolution
- Optional IEEE 1588 PTP time synchronization over network
The Pixie-Net combines an embedded Linux system with XIA’s digital pulse processing developed on the Pixie PXI/PXIe spectrometer series. Incoming signals are digitized at 250 MSPS with 12-bit ADCs. Using a ZYNQ All Programmable SoC with programmable logic (FPGA) and a dual-core ARM® processor on the same chip, the ADC data stream is captured and processed in the FPGA section and the ARM processor writes the results to a local SD card or USB drive, or makes them available on a web server. Multiple units can share signals though GPIO.
