5.7 Digital I/Q Output Settings
The output of the digital baseband signal requires the option R&S SMBV-K18, Digital
Baseband Connectivity. If this option is connected, the instrument adds as separate
function block to the block diagram, the "BB In/Out" block.
If digital Output is selected, the R&S SMBV displays "DIG I/Q OUT" and a corresponding
symbol in the "BB In/Out" block.
The digital baseband signal is output at a standardized (LVDS) digital I/Q interface.
The settings dialogs for the digital signal output is available in the "BB In/Out" function
block as well as in the menu with the same name which is opened using the MENU key.
To access the settings for the digital I/Q output:
1. select "Block Diagram > BB In/Out > Config... > Baseband Output Settings" or
2. press the MENU key and select "BB In/Out > Baseband Output Settings".
