PDFNI has developed a number of signal conditioning and data acquisition options to fit your particular application, featuring flexible signal connectivity, modularity, and software configurability. These options range from simple and secure wireless data acquisition (NI Wi-Fi DAQ) to plug-and-play USB data acquisition systems featuring hot-swappable modules and built-in signal conditioning (NI CompactDAQ) to rugged, multichannel systems for large applications (SCXI).
