Overview

The DT5761 is the 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 offline 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 CAEN 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 specific acquisition systems.

The DT5761 comes in a Desktop form factor with 1 input channel. The communication to and from the board is provided through USB and Optical Link interfaces.
