LXI Classes and LXI functionality
LXI-compliant instruments are divided into three classes, A, B and C, with the
functionality of the classes hierarchically based one upon the other:
●
Class C
instruments are characterized by a common LAN implementation,
including an ICMP ping responder for diagnostics. The instruments can be
configured via a web browser; a LAN Configuration Initialize (LCI) mechanism
resets the LAN configuration. The LXI Class C instruments shall also support
automatic detection in a LAN via the VXI-11 discovery protocol and program-
ming by means of IVI drivers.
●
Class B
adds IEEE 1588 Precision Time Protocol (PTP) and peer-to-peer
communication to the base class. IEEE 1588 allows all instruments on the
same network to automatically synchronize to the most accurate clock availa-
ble and then provide time stamps or time-based synchronization signals to all
instruments with exceptional accuracy.
●
Class A
instruments are additionally equipped with the eight-channel hard-
ware trigger bus (LVDS interface) defined in the LXI standard.
For information about the LXI standard refer to the LXI website at
