Many engineers are building test systems based on Ethernet/LAN platforms. LXI standardizes and extends Ethernet LAN technology to serve test-and-measure-ment applications, supporting instant and uniform discovery of instruments on a network and providing for time synchronization among geographically dispersed instruments. LXI also provides for debugging and interoperability of instrument systems, and it offers the consistency of a uniform standard across multiple sites and test systems.LXI offers many advantages over traditional GPIB implementations, which have a theoretical maximum bus speed of 1 Mbyte/s. In addition, GPIB supports a maximum of 14 instruments on the bus at one time, maximum cable length is 2 m, and cables cost over $100. GPIB systems also require a GPIB controller card or a USB adapter.
