Overview and Applications
National Instruments high-speed voltage output devices combine the
latest in PC technologies to deliver simultaneous, multichannel updates
for control and waveform output applications. Use these modules in a
variety of applications, including:
• Stimulus/response
• Power supply control
• High-speed, deterministic control
• Sensor/signal simulation
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 to create a sine wave
that is overlaid with noise in which the amplitude and noise shape are
user-defined. In practice, the waveform is defined in a software buffer,
within PC memory, and is streamed to the voltage output device using
direct memory access (DMA) data transfers. Using DMA transfers, the
amount of memory located on board the voltage output device is
minimized and is swapped with inexpensive PC memory.
Features
The versatile NI high-speed voltage output devices commonly replace
several kinds of instruments including stand-alone PID controllers, low-speed
arbitrary waveform generators, and function generators.
Real-Time Control
You 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, cutting-edge control algorithms
as well. High-performance control, on the order of eight PID loops running
in excess of 20 kHz each, is possible with this combination of hardware
Waveform Generation
These devices are capable of updating at rates up to 1 MS/s, giving you
the ability to generate waveforms up to 500 kHz. When using these
High-Speed Voltage Output – up to 1 MS/s/Channel, up to 16 Bits, up to 32 Channels
and software. Each high-speed voltage output device offers multichannel
simultaneous updates and hardware-timed single-point updates.
into more than 400 LabVIEW built-in analysis routines for display of
results in engineering units on a graph.
Multidevice Synchronization
Each high-speed voltage output device offers the ability to be master or
slave of a multidevice timing and triggering system. Use integration
technologies such as the RTSI bus, PXI trigger bus, and PFI pins to trigger
and synchronize to a wide variety of I/O types. These I/O types range
from analog input, image acquisition, motion control, and high-speed
digitizers to multifunction data acquisition devices. With these
integration infrastructures, you can create powerful, custom test and
control systems with ease.
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. It features
ready-to-use LabVIEW VIs and C function features similar to those
included in NI-DAQmx driver software.

Measurement Services Software
National Instruments measurement services software, built around
NI-DAQmx driver software, features intuitive application programming
interfaces, configuration tools, I/O assistants, and other tools designed
to reduce system setup, configuration, and development time. This software,
part of your data acquisition purchase, includes helpful features such as:
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 NI LabVIEW, LabWindows/CVI, or Measurement Studio.
Cleaner Code Development
– Basic and advanced software functions
have been combined into one easy-to-use yet powerful set to help you
build cleaner code and move from basic to advanced applications
without replacing functions.
High-Performance Driver Engine
– NI-DAQmx delivers maximum
I/O system throughput with a multithreaded driver.
Test Panels
– With the Measurement & 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
