This document lists specifications for the PXIe-4322 16-Bit, 8-Channel, 250 kS/s Ch-Ch Isolated PXI Analog Output module. These specifications are typical for the range of 0 °C to 55 °C unless otherwise stated. The system must be allowed to warm up for 15 minutes to achieve the rated accuracy. All specifications are subject to change without notice. Visit ni.com/manuals for the most current specifications and product documentation.
To maintain forced-air cooling for PXI/PXI Express devices, make sure the PXI/PCI chassis fan speed is set to HIGH, the foam fan filters are removed if present, and the empty slots contain slot blockers and filler panels. For more information about cooling, refer to the Maintain Forced-Air Cooling Note to Users.
