To access and configure the "Baseband Input" settings
The "BB Input" block provides access to the settings for signal routing, frequency offset
and path gain, and to the available configuration parameters of the external signal.
The digital baseband input interfaces DIG I/Q are located on the R&S SMW rear panel,
see Figure 3-1.
In the default instrument state, the block diagram displays the connector in an unfolded
state. The digital input interfaces are inactive (gray LEDs).
1. To display the "BB Input" block if the connectors are folded, select the symbol
"CODER 1/2"

1 = digital input interface state: gray = inactive; blue = active
2 = connector name
2. To access the routing settings, select "BB Input > Signal Routing".
See Chapter 3, "Signal Routing and System Configuration", on page 122.
3. To access the frequency offset and path gain settings, select "BB Input > Base-
band Offsets".
See Chapter 4.12, "Shifting and Boosting the Baseband Signal", on page 382.
4. To access the dialog box for configuring the external signal input depending on the
current "System Configuration > Fading/Baseband Configuration", select one of the
following:
● "BB Input > Digital I/Q In > Baseband Input Settings"
● "Baseband > Digital I/Q In > Baseband Input Settings"
The "Baseband Input Settings" dialog provides settings necessary to define the
used connector, to adjust the signal parameters, like the sample rate, the base-
band input level and to perform simple signal monitoring.
