b) Define the "Connection Mode" between R&S
SMW and R&S
FE50DTR:
● "Auto": Default setting. If the R&S
SMW outputs the IF signal ("RF" >
"On") to the external frontend. The R&S
SMW locks the external fron-
tend and uses the external frontend exclusively.
● "Lock": The R&S
SMW locks the external frontend permanently.
● "Simultaneous RX/TX": The R&S
SMW locks the SSL connection to the
external frontend once for Tx operation and releases the external fron-
tend. A connected vector signal analyzer can take over control of the
external frontend, see
5. In the "System Config > System Configuration > External RF und I/Q" dialog,
check the control connection state.
The "RF A" > "Rem Conn" field displays an active control connection:
The control connection is established, the LAN LED on the front panel of the
R&S
FE50DTR switches from green to orange.
If you change the network configuration, e.g. the IP address, the connection
to the R&S
FE50DTR is aborted. You must re-establish a connection to the
frontend as in step 3).
If you have connection issues, see section „Troubleshooting External Frontend
Control“ in the R&S
SMW-K553 Frontend Control user manual.
