Intended as the successor to GPIB, LXI uses Ethernet as the physical connection to external instruments (i.e. instruments not integrated within the computer). This increases data rates, simplifies wiring and allows the maximum distance between instruments and the host computer to be increased to tens of metres. Timing synchronisation and triggering over ethernet are also supported.
LXI compliance mandates that an instrument must have an IVI Driver, thereby ensuring greater consistency in software programming. If the instrument matches one of the defined IVI classes, then the driver will be IVI Class Compliant. The LXI standard is maintained and promoted by the LXI Consortium.
