Starting a remote control over LAN (using VXI-11)
To set the instrument to remote control, you can use the addressed command >R, or
send any command from the controller.
1. Start the R&S VISA Tester and establish the connection to the R&S SMB, see
"Configuring the controller" on page 247.
2. In the R&S VISA "Basics" tab, enter a SCPI command, e.g. "*IDN?" and confirm
with "Query".
The instrument is switched to remote control when it receives a command from the
controller.
3. Select "Read" to obtain the instrument response.
Tip: If the "Show Log" checkbox is checked R&S VISA displays each VISA function
call in the log-view on the left. If you check the "Write Log" checkbox the log-view
entry is written to the log file as well. You can operate the log-view in two modes:
the "Live Mode" shows only the most recent messages whereas the "View Mode"
allows you to scroll the history.
4. To set, e.g. the frequency, enter SOUR1:FREQ 4 GHz and select "Write".
To check the performed setting, SOUR1:FREQ? and select "Read".
