A waveform digitizer can be used to digitally record and analyze signal curves. The functionality is similar to that of the digital storage oscilloscope; however, the measurement data are processed and evaluated not manually, but with the help of a computer. Waveform digitizers are generally characterized by compactness (PXI/PXIe plug-in module) and high performance (accuracy, resolution, data transfer rate). They are therefore particularly suitable for applications with a high degree of automation.
