Some settings are also available in the "Amplitude" tab of the "Amplitude" dialog box.
Since the Digital I/Q input and the Analog Baseband input use the same digital signal
path, both cannot be used simultaneously. When one is activated, established connec-
tions for the other are disconnected. When the second input is deactivated, connec-
tions to the first are re-established. This may cause a short delay in data transfer after
switching the input source.
External mixers are not supported in MSRA/MSRT mode.
