The NI PCI-6281 is a high-accuracy multifunction M Series data acquisition (DAQ) board optimized for 18-bit analog input accuracy. This resolution is equivalent to 5½ digits for DC measurements. To ensure accuracy, the NI-PGIA 2 amplifier technology is optimized for high linearity and fast settling to 18 bits, and programmable lowpass filters reject high-frequency noise and prevent aliasing.

High-accuracy M Series devices feature programmable offsets and references on the analog output channels to obtain maximum 16-bit resolution on any custom signal. High-accuracy M Series multifunction DAQ devices are ideal for applications including device test and characterization, and for sensor and signal measurements requiring instrument-class accuracy. To download the certification certificate for a particular DAQ device, visit ni.com/calibration, select "Generate a copy of your current calibration online," and enter the serial number of the DAQ device.

Driver Software
M Series devices work with multiple operating systems using three driver software options including NI-DAQmx, NI-DAQmx Base, and the Measurement Hardware DDK. Browse the information in the Resources tab to learn more about driver software or download a driver. M Series devices are not compatible with the Traditional NI-DAQ (Legacy) driver.

Application Development Environments
With NI LabVIEW, you can create custom data acquisition applications with the ease of graphical programming and power of more than 500 analysis functions and advanced programming tools. LabVIEW Full and Professional Development Systems include LabVIEW SignalExpress for interactive data logging. M Series DAQ devices are compatible with the following versions (or later) of NI application software – LabVIEW 7.x, LabWindows™/CVI 7.x, or Measurement Studio 7.x; LabVIEW SignalExpress 1.x; or LabVIEW with the LabVIEW Real-Time Module 7.1. M Series DAQ devices are also compatible with Visual Studio .NET, ANSI C/C++, and Visual Basic 6.0.
