The LXI stands for LAN eXtensions for Instrumentation. It is a communication standard for test and measurement instruments that leverages the power and ubiquity of standard Ethernet (LAN) technology. Developed and maintained by the LXI Consortium, it is positioned as the modern successor to the older GPIB (IEEE-488) standard. LXI-compliant instruments use a standard Ethernet port for communication, allowing them to be easily integrated into existing network infrastructure. This provides the benefits of high speed, long-distance control, and a simplified, one-cable connection for both control and data. However, LXI is more than just using Ethernet for communication; it defines a set of rules and features that ensure interoperability and enhance usability.
For example, all LXI-compliant devices must have a built-in web server that provides a standard interface for viewing the instrument's identity and configuring its network settings. The standard also defines mechanisms for precise synchronization between instruments using hardware-based triggers sent over the network (LXI Events), allowing multiple devices to be coordinated with high precision. By building on top of proven, standard technologies like Ethernet and TCP/IP, LXI provides a powerful, flexible, and cost-effective platform for building modern test and measurement systems, from simple benchtop setups to large, distributed automated test equipment (ATE).
