XIA ports Digital Signal Processing technology to ZYNQ SoC

In its latest miniaturized Digital Signal Processor, the Pixie-Net, XIA has embedded patented multi-channel Digital Signal Processing technology into a single ZYNQ SoC device. With an on-board Linux platform supporting a web interface, the Pixie-Net can be controlled by any on-line device.  No external PC required!

The Pixie-Net is a standalone multi-channel data acquisition system for high precision gamma-ray spectroscopy that eliminates the need for a host PC.  It combines an embedded Linux system with XIA’s tried-and-tested digital pulse processing algorithms developed for the Pixie PXI series. Incoming signals are digitized at 125-500 MSPS with 12-16 bit ADCs, depending on the option purchased. Using a ZYNQ All Programmable SoC with programmable logic (FPGA) and dual-core ARM®processor on the same chip, Pixie-Net output data is written to a local micro SD card, a removable USB drive, or made available on a web server.  Linux GPIO can be configured for PMOD® peripherals, including GPS, wifi and serial port modules. Network control includes acquisition set up, start/stop, monitoring, and data sharing.

Designed for high-precision coincidence gamma-ray spectroscopy using HPGe detectors, scintillators, or silicon detectors, the Pixie-Net offers not only waveform digitization and capture but also pulse height measurements, on-board energy histograms, time stamping and constant fraction timing, pileup inspection, external gating and online pulse shape analysis. Besides nuclear spectroscopy, the Pixie-Net can be used for neutron/gamma discrimination, time-of-flight measurements, and coincidence/anti-coincidence measurements.
