To connect an R&S FE50DTR
The R&S FE50DTR and R&S SMW are switched on and connected to power. At the
R&S FE50DTR, you connect the IF input signal from the R&S SMW, to the "IF In A" or
"IF In B" connector.
► To connect an R&S FE50DTR with the R&S SMW, follow the instructions described
in section "To connect an R&S FE44S" on page 12.
Table 3-3 and Figure 3-2 provide an overview on connections and a test setup.

3.2 Controlling external frontends
To configure the R&S SMW for frontend control
The following procedure describes how to configure the R&S SMW to establish a con-
trol connection between R&S SMW and an external frontend.
The R&S SMW is connected to the R&S FE44S, see "To connect an R&S FE44S"
on page 12. Configuration with other connected external frontends is analogous.
1. Select "Taskbar > System Config > System Configuration > External RF und I/Q".
2. Select "RF A > External Instrument > Config".
The "External Instrument Configuration" dialog opens.
