NI PXIe-1071 PXIe, 4-Slot, Up to 3 GB/s PXI Chassis

The NI PXIe-1071 is a 4-slot, 3U PXI Express chassis engineered for modular test and measurement systems requiring high-bandwidth signal distribution. It delivers up to 3 GB/s maximum system bandwidth through a PXI Express backplane, supporting demanding applications in automated test, data acquisition, and instrumentation. The chassis accommodates both PXI Express modules and standard PXI hybrid-compatible modules across three peripheral slots plus one system slot with three expansion slots, enabling flexible configurations for diverse measurement requirements.
