programming 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 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 trigger 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 network analyzer complies with LXI class C. In addition to the general class C features described
above, it provides the following LXI-related functionality:
Integrated LXI Configuration dialog for LXI activation and reset of the LAN configuration (LAN
Configuration Initialize, LCI)
The LXI functionality requires a Windows XP operating system with service pack 2 or higher. Please
contact your Rohde & Schwarz service representative if your network analyzer's operating system needs
an upgrade. To check the version of your operating system, open the System – General dialog in the
Control Panel.
After a firmware update, use the standby key to shut-down and re-start the instrument in order to enable
the full LXI functionality.
For instruments running Windows 7, LXI is currently not fully supported.
For information about the LXI standard refer to the LXI website at http://www.lxistandard.org. See also
"News from Rohde & Schwarz, article 2006/II - 190".
LXI Configuration Dialog
This tab provides basic LXI functions for the analyzer. LXI Configuration is a tab of the System – System
Configuration dialog.
