PCI High-Accuracy (Up to 625 kS/s, 32 Ch, 18-Bit)

Designed for performance, National Instruments high-accuracy multifunction data acquisition (DAQ) devices are optimized for 18-bit analog input accuracy. This resolution is equivalent to 5½ digits of precision for DC measurements. To ensure accuracy, the NI-PGIA 2 amplification circuitry provides high linearity and fast settling to 18 bits, and programmable lowpass filters reject high-frequency noise and prevent aliasing. These high-accuracy devices also feature programmable offset and reference settings on analog output channels to maximize 16-bit resolution for custom signal generation.

The 18-bit multifunction DAQ devices are ideal for a wide variety of applications including device test and characterization, and for sensor and signal measurements requiring instrument-class accuracy. To learn more about absolute accuracy specifications, refer to the Specifications tab on individual product pages.
