Compare Signal Conditioning Families

NI has developed a number of signal conditioning options to fit your particular data acquisition system, featuring flexible signal connectivity, modularity, and software configurability. These options range from portable, low-cost signal conditioning systems (SCC) 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 requiring superior performance (SCXI).
