Testing locomotive boards with PXI: the 20+ PCBs on board diesel locomotives survive a very tough combination of functional and environmental testing before they leave the roundhouse

Several companies that manufactured ISA bus cards such as DMMs, universal time interval counters, and ROM emulators created 3U and 6U PXI versions of their products.

PXI-gration provides solution for obsolete test systems: with so many legacy or obsolete test systems in use today, customers are searching for solutions to ease the replacement pain

The primary shortcoming of ROM emulators is the inability to diagnose the processor to boot ROM area.
