cPCI / PXI / PXIe Crates
CompactPCI ratified as PICMG 2.0 in late 1995 is an interconnect bus standard for industrial computers, combining a 3U or 6U Eurocard-type card and PCI signaling / protocols via a passive backplane with metric connectors. PXI (PCI eXtensions for Instrumentation) is the application of CompactPCI for measurement and automation systems. PXI uses commercial PC-based PCI bus technology while combining rugged CompactPCI modular packaging with timing and synchronization features in order to provide an optimized basis for complex, rugged, modular instrumentation systems. The PXI standard is governed by the PXI systems Alliance (PXISA)
