NI PXI-1042 8-Slot 3U PXI Chassis

The NI PXI-1042 is an 8-slot, 3U PXI chassis engineered for modular test and measurement systems requiring high-performance signal distribution and synchronized timing. This chassis accepts both 3U PXI and CompactPCI modules, delivering 132 MB/s maximum system bandwidth across a CompactPCI 64-bit compliant backplane. The design emphasizes maintainability through modular construction while supporting up to 25 W per slot thermal capacity.

– Technical Specifications
