National Instruments PXI-6722

The National Instruments PXI-6722 (Part Number: 778999-01) is a versatile PXI Analog Output Module designed for high-density applications, featuring 32 analog output channels with a sampling rate of up to 45 kS/s per channel and 13-bit resolution. This module supports a maximum update rate of 800 kS/s and provides an analog output voltage range of -10 V to 10 V. Additionally, the PXI-6722 is equipped with eight digital I/O lines and two 24-bit counter/timers, allowing for comprehensive control and synchronization with other data acquisition, motion, and vision systems via the PXI trigger bus. Ideal for applications requiring precise waveform generation—including shock response, signal recreation, and actuator stimulation—the PXI-6722 works seamlessly with NI Analog Waveform Editor software, which enables users to create complex waveforms from over 20 built-in waveform primitives or through custom formula entry. The module also allows for the generation of tailored waveforms, such as sine waves with user-defined noise characteristics, by utilizing direct memory access (DMA) to stream waveform data from PC memory to the analog outputs. Compatible with NIDAQmx driver software, the PXI-6722 integrates well with development environments such as LabVIEW and LabWindows/CVI. It features a 68-pin VHDCI I/O connector and operates within a temperature range of 0 °C to 50 °C, with storage capabilities between -20 °C to 70 °C. While the PXI-6722 has been designated as a mature product by National Instruments, it remains available for purchase and repair through Apex Waves, ensuring ongoing support for users.
