"Setting up the controller with R&S VISA"
2. In the R&S VISA "Basics" tab, enter an SCPI command, e.g. "*IDN?". 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 "Query".
The instrument response is
4000000000
. The value corresponds to the frequency
in Hz.
While remote control is active, the "Remote" icon in the status bar indicates that the
instrument is in remote control mode. Currently ongoing communication (data
transfer) is indicated by green colored arrows in the icon.
Additionally, the "Connections" softkey in the taskbar shows the currently estab-
lished remote connections. The operation via the front and touch panel or via
mouse and keyboard are locked, allowing a remote control program to be per-
formed without interruption.
On the display, keys and entry fields are grayed out and cannot be activated or
modified, but you can still open dialogs, for example to verify settings.
