PXIe (PCI eXtensions for Instrumentation Express) interfaces are specifically designed for test and measurement applications, offering a standardized platform for connecting instrumentation and control systems. They are widely used in aerospace/defense testing to ensure precise timing and synchronization among multiple instruments. Utilizing the PXIe chassis and modular architecture, PXIe interfaces allow for easy insertion and exchange of modules within the system. Further, PXIe interfaces are complemented by specialized software and drivers tailored for test and measurement, providing additional tools and libraries for instrument control and data acquisition.
