Measure immediately

With DaErf, the data acquisition software from Aucodys, you can easily record signals using an NI card (In the Free Version only possible with one signal at the time).

Low pass filter

To avoid antialiasing in the acquired digital data, the application contains two low-pass filters for selection. In this way you can downsample the data for saving without signal error.


Capture, storage and further processing

Save the data in the professional tdms format of LabVIEW. The application contains an integrated View mode for your recordings and allows you to export them as text files.
