8-4/4-2 Ch. 10-bit 1/2 GS/s Digitizer

Digitizers 1.0

751 Digitizer Family

The 751 is a family of CAEN Waveform Digitizer able to perform basic waveform recording and run online advanced algorithms (DPP) of charge integration and pulse shape discrimination with constant fraction timing and zero-length encoding. Data is read by a Flash ADC, 10-bit resolution and 1GS/s sampling rate (2GS/s using half of the channels in DES mode), which is well suited for fast signals as the ones coming from fast organic, inorganic and liquid scintillators coupled to PMTs or Silicon Photomultipliers, Diamond detectors and others. The acquisition can be channel independent and it is possible to make coincidence/ anti-coincidence logic among diferent channels and external veto/ gating. Multiple boards can be synchronized to build up complex systems.

In case of DPP mode, data can be saved in time-stamped list mode to support higher input rates and improving the throughput performances. Piled-up events can be rejected or saved for offline analysis. The acquisition in DPP mode is fully controlled by the CoMPASS software, which manages the algorithm parameters, builds, plots and saves the relevant energy, time, and PSD spectra. In case of waveform recording mode, the user can take advantage of the CAENScope and WaveDump software to access and save the waveforms. Libraries and demo software in C and LabView are available for integration and customization of specifc acquisition systems. 751 family comes in three form factors: VME (8-4 input channels), NIM (4-2 input channels) and Desktop (4-2 input channels). The communication to and from the board is provided through the following interfaces: USB (Desktop and NIM form factors), VMEbus (VME form factor), and Optical Link (all form factors).

Interfaces & I/O

USB An USB 2.0 link is provided in NIM and Desktop form factors for an easy data readout VME Digitizer can be controlled via USB using the CAEN V3718 VME-USB2.0 Bridge

Optical Link An Optical link is provided in any form factor for high performance data readout through CAEN proprietary daisy-chainable CONET communication protocol. it is possible to connect up to 8/32 ADC modules to a single Optical Link Controller (Mod. A4818/A3818)

Digital I/O Digital I/Os are provided in VME boards that can be used for individual trigger propagation to external trigger logic. This feature makes VME form factor ideal to scale up the acquisition channels where a global trigger generation is mandatory.
