Chapter 1 Introduction Using PXI with CompactPCI Using PXI-compatible products with standard CompactPCI products is an important feature provided by the PXI Specification, Revision 1.0. If you use a PXI-compatible plug-in device in a standard CompactPCI chassis, you will be unable to use PXI-specific functions, but you can still use the basic plug-in device functions. All 6527 device functions are available in a CompactPCI chassis. The CompactPCI specification permits vendors to develop sub
