●
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. The LXI class C instruments shall also support automatic detection
in a LAN via the VXI-11 discovery protocol and programming by means of IVI driv-
ers.
●
Class B adds IEEE 1588 Precision Time Protocol (PTP) and peer-to-peer commu-
nication to the base class. IEEE 1588 allows all instruments on the same network
to automatically synchronize to the most accurate clock available and then provide
time stamps or time-based synchronization signals to all instruments with excep-
tional accuracy.
●
Class A instruments are additionally equipped with the eight-channel hardware
trigger bus (LVDS interface) defined in the LXI standard.
For information about the LXI standard refer to the LXI website at http://www.lxistan-
dard.org . See also "News from Rohde & Schwarz, article 2006/II - 190".
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 SMJ complies with LXI class C and provides an integrated "LXI Status" dia-
log for LXI status indication and reset of the LAN configuration (LAN Configuration Initi-
alize, LCI). To accesss the LXI Status dialog, press the SETUP key and select
"Remote > LXI Status".
For further information, see section "LXI Status" in the Operating Manual.
Firmware update
After a firmware update, shut-down and re-start the instrument in order to enable the
full LXI functionality.
