●
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 UPP meets the general requirements of LXI Class C. In addition to the prop-
erties 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.
2.10.3.2 LXI LAN Indicator
The green LAN LED on the front panel of the R&S UPP shows the LAN status of the
instrument. The LAN LED indicator has three states.

The instrument does not have valid IP address. This may be due to one of the
following reasons:
1) the instrument is configured with DHCP, but no DHCP router is connected,
2) the instrument is manually configured and an IP address conflict is present,
