2.4.6.1 RF Signal Routing
Depending on the selected scenario, this section configures only the RF input path, or
one input and one output path, or one input and two output paths. Most parameters are
configurable per path.
For carrier aggregation scenarios, you can configure different PCC and SCC downlink
settings (except "External Delay Compensation").

RF Output (TX)
The following parameters configure the RF output paths of the R&S CMW.
Connector, Converter ← RF Output (TX)
Selects the output paths for the generated RF signals, that means the output connector
and the TX module for each downlink path.
Depending on your hardware configuration, there are dependencies between both
parameters.

External Attenuation ← RF Output (TX)
Defines the value of an external attenuation (or gain, if the value is negative) in the out-
put path. With an external attenuation of x dB, the power of the generated signal is
increased by x dB. The actual generated levels are equal to the displayed values plus
the external attenuation.
