LXI Configuration
1.1 LXI Configuration
LAN eXtensions for Instrumentation (LXI) is an instrumentation plattform for measuring
instruments and test systems that is based on standard Ethernet technology. LXI is
intended to be the LAN-based successor to GPIB, combining the advantages of Ethernet with the simplicity and familiarity of GPIB.
Like GPIB, LXI determines and standardizes the way the instrument behaves in a LAN.
The LXI implementation by the Rohde & Schwarz Signal Generators allows you to
change certain LAN settings, to reset the LAN connection as well as to easy identify
the instrument.
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".
The R&S AFQ complies with LXI and provides an integrated "LXI Status" dialog for LXI
status indication and reset of the LAN configuration (LAN Configuration Initialize, LCI).
To access the LXI Status dialog, press the SETUP key and select "Remote > LXI Status".
For further information, see Chapter 1.2, "LXI Status", on page 10.
Firmware update
After a firmware update, shut-down and re-start the instrument in order to enable the
full LXI functionality.
Default state of the network settings
According to the LXI standard, an LCI must set the following parameters to a default
state.

LXI Configuration
The LAN settings are configured using the instrument's .
1.1.1 LXI Browser Settings
The instrument's LXI browser interface works correctly with all W3C compliant browsers.
Typing the instrument's host name (LAN device name) or IP address in the address
field of the browser on your PC opens the "Instrument Home Page" (welcome page).
To access the instrument via the web browser:
► Type in the instrument's host name or IP address in the address field of the
browser on your PC, for example http://10.111.10.205.
Tip: The specific IP address (host address / instrument name) is used by the controller programs to identify and control the instrument. It is automatically assigned
by the DHCP server the first time the instrument is registered on the network. The
host name is usually composed of the instrument name and the serial number:
<instrument name><serial number>, e.g. RSAFQ100B1000011.
Note: Do not add the missing zeros in the IP address, while opening the instrument home page.
The instrument home page (welcome page) opens.

LXI Configuration
The "Instrument Home Page" displays the device information required by the LXI
standard including the VISA resource string in read-only format.
The navigation pane of the browser interface contains the following elements:
●
"LXI"
– "Home" opens the instrument home page.
The home page displays the device information required by the LXI standard,
including the VISA resource string in read-only format.
– "Device Indicator" activates or deactivates the LXI status indication.
When activated, the LXI LEDs flash, both in the browser dialog and in the LXI
dialog of the connected instrument. A green LXI status symbol indicates that a
LAN connection has been established; a red symbol indicates that no LAN
cable is connected.
– "Lan Configuration" allows you to configure LAN parameters and to initiate a
ping, see Chapter 1.1.2.3, "Ping Parameter", on page 7.
– "Status" displays information about the LXI status of the instrument.
– "Utilities" provides access to the LXI event log functionality required by the LXI
standard.
●
"Instrument Control"
– "Web Control" provides remote access to the instrument, see Chapter 1.1.2.4,
"Web Control", on page 8 .
●
"Diagnostics"
– "SCPI Remote Trace" records messages exchanged via the remote control
interface, see Chapter 1.1.2.5, "SCPI Remote Trace", on page 9.
●
"Help"
– "Glossary" explains terms related to the LXI standard.
– www.rohde-schwarz.com opens the Rohde & Schwarz home page.

► Press the "Inactive (press to toggle)" button to activate the connection.
A green flashing status LED indicates the active connection. If the LAN connection
fails, the LED turns red.
The status of the LAN connection is also indicated by the "LAN Status indicator" in
the "LXI Status" dialog.
The "Device Indicator" setting is not password-protected.
For further information, see section Chapter 1.2, "LXI Status", on page 10.
The navigation pane of the browser interface contains the following control elements:
●
"LAN Configuration" opens the LAN Configuration page.
●
"LXI Glossary" opens a document with a glossary of terms related to the LXI standard.
●
"Status" displays information about the LXI status of the instrument.
