National Instruments Product Guide - 2008 - (Page 18) NI Data Acquisition and Signal Conditioning The purpose of data acquisition is to measure a physical or electrical phenomenon such as voltage, current, temperature, pressure, or sound. PC-based data acquisition uses a combination of measurement hardware and software to provide a flexible, user-defined system for automating measurements and making data available for analysis. While each data acquisition system is uniquely defined by its application requirements, every system shares the common goal of acquiring, analyzing, and presenting information. Use NI data acquisition (DAQ) to solve application challenges for any sensor on any bus with any programming language. Industrial Features High-voltage isolation, 24 V digital I/O, ±20 mA current I/O Direct Connectivity Built-in signal conditioning High Accuracy Up to 18 bits of resolution NI Signal Streaming Simultaneous, bidirectional, high-speed USB data streams High Reliability User-defined FPGA I/O timing and synchronization The NI Measurement Difference Any Bus — The most complete family of data acquisition devices for PCI, PCI Express, PXI, PXI Express, PCMCIA, USB, and CompactFlash Any Sensor — Signal conditioning for high- or low-channel-count systems and a wide range of sensors, including strain, temperature, high-voltage, and pressure Any Language — Application development in NI LabVIEW, LabWindows™/CVI, ANSI C/C++, C#, Visual Basic .NET, and Visual Basic 6.0 with a common API 18 ni.com The mark LabWindows is used under a license from Microsoft Corporation. http://ni.com
