The NI PCI-6722 is an 8-channel analog output device for static and waveform generation on PCI bus systems. It delivers 13-bit resolution at up to 800 kS/s per channel across a ±10 V output range, supporting waveform generation up to 500 kHz including sine, square, sawtooth, and complex signal types. The card functions as both a deterministic control instrument and arbitrary waveform generator, suitable for stimulus-response testing, power supply control, sensor simulation, and real-time PID implementations.
