Defining three classes of LAN eXtensions for Instrumentation (LXI)

LXI Class C: The base class of LXI. These devices must have a standard Ethernet interface, serve a Web interface viewable from a standard web browser, provide an IVI driver for programmatic interface, and adhere to industry standard EMI, cooling, and IEC rack sizes.

LXI Class B: Class B devices must meet all the Class C requirements plus they add IEEE 1588 precision time protocol. Also included in Class B is the ability of a device to do peer-to-peer and multi-cast messaging over LAN.

LXI Class A: Class A devices must meet all the requirements of Class C and Class B and add the LXI trigger bus, a hardware trigger that connects devices in close proximity.

Physically, standalone LXI instruments may be full- or half-rack width and tall enough to accommodate the front-panel display and keypad. Modular LXI instruments (without a display or keyboard) are typically half- or fullrack width and just 1U or 2U high. All signal connections—inputs and outputs—are on the front panel; power and I/O connections are on the back.
