Connect/Disconnect ← Signal Generator IP Address
The R&S FSW attempts to establish a connection to the signal generator, or discon-
nects it.
If an instrument is connected, the following information is displayed:
●
Device type
●
Name and serial number
●
Connection state
Remote command:

Generator Control State (FSW -> SMW)
Activates or disables control of the signal generator by the R&S FSW.
If a connection was defined in another application, the connection is maintained when
you switch to the Spectrum application. However, generator control is disabled to pro-
tect the DUT from possibly erroneous or damaging settings. Check the settings, then
enable the control state.
Note: While generator control is active, you cannot change the connection information.
When you switch applications, the control is disabled in the other applications. Only
one application can control a generator at any time.
As long as the R&S
FSW controls the signal generator, any (general) generator set-
tings you define on the R&S FSW are automatically adapted on the generator. The
opposite does not apply, that is: changes you make on the generator are not automati-
cally applied to the R&S
FSW. The green LED for a previous successful transmission
does not change. Use the Query all Generator Setup Settings from Generator function
to apply the generator settings on the R&S FSW.

Path RF/ Path BB
Selects the RF signal path and indicates the BB signal path of the generator to be used
for signal generation.

RF Output State
To protect the instrument from possibly erroneous or damaging settings, you must
manually activate the RF output on the signal generator to start providing a signal.
Check all settings on the signal generator, in particular the level settings, before acti-
vating the RF output.
A red LED on the "Generator Control" tab indicates a setting error on the generator.
