WAVEDUMP2

WaveDump2 is an open-source C++ readout application for CAEN waveform digitisers, developed on the Qt cross-platform framework. It provides a comprehensive graphical user interface for the complete configuration of acquisition hardware, covering both global board parameters and channel-level settings such as trigger thresholds, DC offsets, and input dynamics. All configuration parameters can be stored and reloaded from a plain-text file, ensuring reproducible experimental conditions.

WaveDump2 is designed to operate with any CAEN Digitizer 2.0 running the Scope firmware for waveform recording. Multi-board data acquisition and the management of synchronised multi-board systems — relevant in complex detector readout architectures — are fully supported through a dedicated toolbar.

Compatibility with the Digitizer 1.0 platform has been implemented via the Dig1 Library, extending support to the 720, 724, 725, 730, 740, and 751 series.

The integrated oscilloscope section provides real-time visualisation of acquired waveforms across up to 8 channels simultaneously. On-screen measurement cursors enable direct quantitative inspection of signal features, while dedicated marker lines indicate the trigger position and threshold level. Individual channel traces can be selectively enabled or disabled, and an on-screen legend facilitates signal identification. Full zooming capability is available on both the time and amplitude axes. Runtime signal processing functions — FFT spectral analysis and sample amplitude histogramming — are directly accessible within the interface, supporting rapid detector performance assessment.

Acquired waveform datasets can be exported in ASCII or binary format for subsequent offline analysis with user-defined analysis frameworks.
