CAEN Digitizer Whitepaper

In recent years CAEN has developed a complete family of digitizers that consists of several models differing in sampling frequency, resolution, form factor and other features. Besides the use of the digitizers as waveform recorders (oscilloscope mode), CAEN offers the possibility to upload special versions of the FPGA firmware that implement algorithms for the Digital Pulse Processing (DPP); when the digitizer runs in DPP mode, it becomes a new instrument that represents a complete digital replacement of most traditional modules such as Multi Channel Analyzers, QDCs, TDCs, Discriminators and many others.

Get up to speed by reviewing the details on this web-based whitepaper, which also highlights all available form factors (VNE / NIM / Desktop) as well as the next generation of digitizers which offer:
  • More density, faster sampling rate, higher resolution for higher performances
  • Increased communication readout through 1/10 Gb Ethernet, USB 3.0 (yet keeping proprietary CONET)
  • Easier multi-board synchronization (clock and timing distribution)
  • Increase of acquisition memory buffer size: from SSRAM to DDR4 (=> from MBs to GBs)
  • Single FPGA (Xilinx Zynq US+ ) architecture => more resources for DPP algorithms and support for “Open FPGA
  • Embedded quad-core ARM (Linux) => middleware, web interface. Possibility to run user Data Processing SW
