11.11 To trace messages with the LXI web browser interface
The remote trace functionality allows you to trace commands and messages
exchanged via a remote control interface of the R&S SMB100B.
To activate SCPI remote trace
1. On the instrument, make sure, that the LAN interface and "SCPI over LAN" are
enabled.
See Chapter 10.4.3, "Configuring LAN services", on page 255.
2. Connect the remote PC and the instrument in the same network.
See also Chapter 3.1.7, "Connecting to LAN", on page 27.
3. Start a web browser that supports HTML5 (W3C compliant).
4. Enter the IP address of the R&S SMB100B in the browser's address bar.
The welcome page is displayed.
5. In the navigation pane, select "Diagnostics > SCPI Remote Trace".
6. In the toolbar bar of the "SCPI Remote Trace" page, select "live mode > on" and
"logging > on".
"live mode > on" displays all commands and responses, and "logging > on" also
traces messages.
If you now control the R&S SMB100B with SCPI commands, using an appropriate
tool, the LXI function records the information sent and received.
The function records all sent commands, received responses and messages, and
saves them in an internal database. If "live mode" is disabled, you can display the
recent traces upon request, using the "refresh" button. You can also save the log in
a file.
Note: The diagnostics functionality is extended in later releases, e.g. to download
or upload SCPI command files from / to the instrument.
