  Pixie16

16-Channel 100/250/500 MHz PXI Digital Processor

  FEATURES

  •  Accepts input signals directly from detector preamplifier outputs or scintillator/PMT combinations.

  •  Signals digitized with 100-500 MSPS, 12-16 bit ADC.

  •  Synchronous acquisition of waveforms up to 163μs in length.

  •  Spectrum from 1K to 32K bins, up to 4.3 billion counts per bin.

  •  Onboard CFD trigger with adjustable parameters.

  •  List mode data buffered to allow zero dead-time acquisition.

  •  PXI backplane trigger distribution and run synchronization.

  •  Full speed 32-bit, 33 MHz PCI interface to host computer, up to 109 MBytes/s readout sustained.

  OVERVIEW

  The Pixie-16 is a 16-channel all digital signal processor on a single 6U CompactPCI/PXI card. Designed for fast coincidence gamma-ray spectroscopy with segmented detectors or detector arrays, it offers both high speed waveform acquisition and MCA anaysis at a low per-channel cost.

  Each channel of the Pixie-16 accepts signals from virtually any radiation detector that has an exponential decay output. Incoming signals are digitized with 12 or 14 or 16-bit, 100 or 250 or 500 MSPS ADCs. The digital data stream is used for triggering, pile-up inspection and filtering in real time. Waveforms with 10 or 4 or 2ns sampling intervals, up to 163μs in length, can be stored in a FIFO. Pulse height reconstruction, incrementing a 32K spectrum for each channel and optional pulse shape anlaysis is performed on an event-by-event basis by a 32- bit floating point digital signal processor (DSP). Waveforms and spectra can be read out at up to 109 Mbyte/s.

  Multiple Pixie-16 modules can be synchronized and share basic triggers through the PXI section of the backplane. More than 160 additional backplane connections can be configured to distribute triggers, share multiplicity or coincidence information, or link the DSPs of different modules.
