For the HW specification installed at at the R&S
Use a bidirectional RF connector for the first forward and reverse signal and a separate
RF connector for the second forward and reverse link. Connect both RF connectors to
an external combiner and connect the combiner to the DUT according to the figure
below.

Test Setup for External Fading Scenarios
In order to superimpose fading on the baseband signal, you can integrate an R&S
AMU200A into a test setup. The R&S AMU200A must be connected to the digital I/Q
interface of the R&S
CMW. At least one I/Q board must be installed at the R&S
CMW
for that purpose (option R&S CMW-B510x/-B520x).
All connections between R&S
CMW and R&S AMU200A are established via the rear
panels of the instruments.
The following figure shows a setup with two downlink paths using the first I/Q board
(DIG IQ 1 to 4).
