The National Instruments PXI-1033 is a 5-slot PXI chassis that serves as a rugged platform for test, measurement, and control applications. Built around PXI Hybrid architecture, it accepts 3U PXI and CompactPCI modules and integrates an MXI-Express controller for remote instrumentation via sustained 110 MB/s throughput. The system provides precision timing, multi-voltage DC distribution, and flexible cooling control in a compact form factor.
