Features
NI high-speed voltage output devices are versatile devices that commonly replace several kinds of instruments including stand- alone PID controllers, low-speed arbitrary waveform generators, and function generators. Waveform Generation These devices are capable of updating at rates up to 1 MS/s, giving them the ability to generate waveforms up to 500 kHz. When using these devices, you have complete control of each data point that is updated on the output for each channel. This feature is significant because you can define not only common waveforms such as square, sine, or sawtooth but also complex waveforms. For instance, you are able t o cr eate a sine wave that is overlaid with noise in which the amplitude and noiseshape is user-defined. In practice, the waveform is defined in a software buffer, within PC memory, and is streamed to the voltage output device using DMA (direct memory access) data transfers. Using DMA transfers, the amount of memory located onboard the voltage output device is minimized and is swapped with inexpensive PC memory. Real-Time Control Y ou can use NI high-speed voltage output devices with the LabVIEW Real-Time Module to deliver real-time, deterministic control loop execution. Because they are compatible with LabVIEW Real-Time, common control algorithms, such as PID, are simple to implement but, more importantly, you may prototype and implement complex and cu tting-edge control algorithms as well. High-performance control, on the order of 8 PID loops running in excess of 20 kHz each, is possible with this combination of hardware and software. Each high-speed voltage output device offers multichannel simultaneous updates and hardware-timed single-point updates.

This software is included with your data acquisition purchase. Helpful features include: Automatic Code Generation – DAQ Assistant is an interactive guide that helps you navigate through configuring, testing, and programming analog output tasks and automatically generates the necessary code for LabVIEW, LabWindows/CVI, or Measurement Studio. Cleaner Code Development – Basic and advanced software functions have b een c ombined int o one easy-to-use yet powerful set to help you b uild c leaner c ode and move from basic to advanced applications without replacing functions. High-Performance Driver Engine – NI-DAQmx d elivers maximum I/O system throughput with a multithreaded driver. Test Panels – With the M easurement & Automation Explorer configuration utility, you can test all of your module functionality before you begin development. Scaled Channels – Easily scale your voltage data into the proper engineering units using the NI-DAQmx Measurement Ready virtual channels by choosing from a list of common sensors and signals or creating your own custom scale. LabVIEW Integration – All NI-DAQmx functions create the waveform data type, which carries acquired data and timing information directly into more than 400 LabVIEW built-in analysis routines for display of results in engineering units on a graph. NI-DAQmx Base Driver NI-DAQmx Base (available at ni.com/downloads) offers Mac OS X and Linux users a programming interface similar to NI-DAQmx.
