2. Enter the IP address of the R&S
SGU in the browser's address bar.
The R&S
SGU's welcome page is displayed.
3. In the navigation pane, select "Diagnostics > SCPI Remote Trace".
4. 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
SGU 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
stores 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 store the log in
a file.

Using the R&S SGMA-GUI to Monitor the Remote
Control Operation
The R&S SGMA-GUI can be used to monitor the behavior of one or more instruments
while they are remote controlled.
A typical configuration consists of one monitor, controllers and instruments. The moni-
tor is the remote PC on which the R&S SGMA-GUI is installed and the controller is the
remote PC on which the application program runs.
Simultaneous control of an instrument from a controller and a monitor may lead to colli-
sions whenever both the controller and the monitor utilize the same remote channel.
These collisions are indicated by an error message in the "Info" line, e.g. "Query inter-
rupted" or "Resource locked". Simultaneous monitoring and control over the same
remote channel is only possible, if the used protocols support
viLock()/viUnlock()
and the remote program use these functions.
shows whether a collision-free communication over a particular combi-
nation of remote channels is possible or not and if there are any restrictions.
