Test system developers generally require a large variety of test instruments to meet system needs. When the instruments are sourced from different suppliers, the system developer must have confidence that they will work well together. Mechanical, electrical and software aspects need to be compatible to ensure successful system operation. Thankfully, due to the work of various standards organizations, the PXI specification promotes hardware and software compatibility between products and suppliers. These organizations defined PCI bus connectivity, chassis, timing, synchronization and software attributes.
