Overview

The 761 is the family of CAEN Waveform Digitizer with the highest sampling rate Flash ADC (10 bit @ 4GS/s). It can record fast signals from fast organic, inorganic and liquid scintillators coupled to PMTs or Silicon Photomultipliers, Diamond detectors and others, and save them with high efficiency and precision for advanced timing analysis. The acquisition can be externally vetoed/gated. Multiple boards can be synchronized to build up complex systems.

The data stream is written in a circular memory buffer with independent read/write access, which reduces the dead-time of the acquisition process. The acquisition is fully controlled by the WaveDump software, which manages the settings, plots and saves the waveforms. Libraries and demo software in C and LabView are available for integration and customization of specifc acquisition systems.

761 family comes in three form factors: VME (2 input channels), NIM (1 input channel) and Desktop (1 input channel). 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).

WaveDump

Open Source Acquisition Software for Developers

 

WaveDump is a basic console application supporting digitizers running Waveform Recording firmware. WaveDump allows the user to program a single board (according to a text configuration file containing a list of parameters and instructions), to start/stop the acquisition. It is then possible to read the data, display the readout and trigger rate. Moreover, it is also possible to apply some post-processing (e.g. FFT and amplitude histogram), save data into a file and also plot the waveforms using Gnuplot third-party graphical utility.

WaveDump is a very helpful example of C code demonstrating the use of libraries and methods for an efficient readout and data analysis. Expert users can start with this demo to write their own acquisition software to exploit the full potentialities of the digitizers. Source files and the VS project are available for free download.

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 V1718 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. A2818/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.
