LXI classes and LXI functionality
LXI-compliant instruments are divided into three classes, A, B and C, with the function-
ality of the classes hierarchically based one upon the other:
●
Class
C instruments are characterized by a common LAN implementation, includ-
ing 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. LXI instruments of class
C must also support automatic detection in
a LAN via the VXI-11 discovery protocol and programming by means of IVI drivers.
●
Class
B adds IEEE 1588 Precision Time Protocol (PTP) and peer-to-peer commu-
nication to the base class
C. IEEE
1588 allows all instruments on the same net-
work to automatically synchronize to the most accurate clock available 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 hardware trig-
ger bus (LVDS interface) defined in the LXI standard.
Instruments of classes A and B can generate and receive software triggers via LAN
messages and communicate with each other without involving the controller.
The R&S UPV66 meets the general requirements of LXI Class C. In addition to the
properties described above, the instrument offers the following LXI-related functions:
●
Integrated display of the current instrument settings
●
Possibility of remote controlling the instrument within the WEB browser.

LXI LAN Indicator
The green LAN LED on the front panel of the R&S UPV66 shows the LAN status of the
instrument. The LAN LED indicator has three states.
