Overview

The NI PCI-6251 is a high-speed multifunction M Series DAQ board optimized for superior accuracy at fast sampling rates. For increased measurement accuracy, consider high-accuracy M Series devices with 18-bit analog-to-digital converters that provide a 4X resolution increase.

High-speed M Series devices incorporate advanced features such as the NI-STC 2 system controller, NI-PGIA 2 programmable amplifier, and NI-MCal calibration technology to increase performance and accuracy. They have an onboard NI-PGIA 2 amplifier designed for fast settling times at high scanning rates, ensuring 16-bit accuracy even when measuring all channels at maximum speeds. To learn more about M Series technologies, device specifications, and information on recommended cables and accessories, please refer to the data sheet and specifications.

Driver Software
M Series devices work with multiple OSs using three driver software options: 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 Software
With NI LabVIEW, you can create custom DAQ 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. They are also compatible with Visual Studio .NET, C/C++, and Visual Basic 6.
