This function will be supported in a future firmware version.
The "Baseband Input" cannot be activated. However, the baseband input related set-
tings in the "Baseband Input" or "System configuration > External RF and I/Q" are dis-
played and described, as are the respective remote control commands.
These settings have no effect because the baseband input interfaces cannot be activa-
ted.
