Acquire, display, evaluate and reproduce measurement curves in high resolution

The best measurements are of little use if the measured values are not processed and evaluated. In addition, results should be presented in such a way that the underlying questions can be answered conclusively. For generating measurement curves, analog-digital converters, which convert voltages or signals from sensors into numerical values, are used. Often, several voltages or signals are fed in parallel into so-called measuring channels, converted and their chronological course recorded so that they can be processed further. CVA - a software for Windows and macOS provided free of charge by Cyclaero serves exactly this purpose of further processing, namely preparation, evaluation and graphic output in high resolution.
