PXI Express is a modular instrumentation platform that combines the benefits of PXI (PCI eXtensions for Instrumentation) with high-speed data transfer capabilities. It is designed for automated testing and measurement applications, allowing engineers to create flexible and scalable test systems. The architecture supports various types of instruments, such as oscilloscopes and signal generators, which can be easily integrated into a single system. With its high bandwidth and low latency, PXI Express enables efficient communication between modules, making it suitable for demanding applications in industries like automotive, aerospace, and telecommunications.
