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.


The digitizers of the PXD product family are digital voltage meters and can record voltage curves or even measure single voltages in 1 or 2 channels (DVM function).

They are characterized particularly by potential-free measuring channels. This allows differential measurements to be carried out with high precision even on high voltage potentials (e.g. high-side measurements). Problems that frequently occur with mass-related measurements are generally avoided.

The very high input impedance and the low input capacitance reduce the influence on the parameter to be measured and thus significantly increase the measuring accuracy. Even high voltages can be captured directly without additional signal conditioning.

A high number of measuring ranges guarantees an optimal resolution of the voltage signal to be measured.
In addition, all digitizers of the PXD series offer an integrated timer/counter function.

An essential advantage is the possibility to combine different function modules in one device, i. e. one digitizer and one arbitrary generator, due to the FlexCP Platform.
