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
