"Auto" The R&S SMW locks external frontend, when activating the RF out-
put at the R&S SMW ("RF" > "On") for output of the IF signal.
The R&S SMW unlocks external frontend, when deactivating the RF
output at the R&S SMW ("RF" > "Off").
"Lock" The external frontend is locked permanently. No other instrument can
take over control.
"Simultaneous RX/TX"
Requires an R&S FE50DTR connected to the R&S SMW.
Connection mode for simultaneous Rx (receive) operation and Tx
(transmit) operation of an R&S
FE50DTR.
Set this mode, if your test setup requires a release of connection lock.
A connected vector signal analyzer can lock the external frontend for
Rx operation.
How to:
"To work with R&S FE50DTR Simultaneous RX/TX connec-
tion mode" on page 17

Intermediate Frequency
Displays the frequency of the IF signal, that is the frequency at the "RF A/RF B" con-
nector of the R&S
SMW.
If the lock of the communication channel is missing, the intermediate frequency dis-
plays "Unavailable due to missing lock".
If you use R&S FE50DTR-type frontends with an analyzer and a signal generator
simultaneously, make sure that the set "Intermediate Frequency" is identical on both
instruments.

Active RF Connector
Displays the RF output connector, that is active at the connected external frontend.
The RF output connector at the connected external frontend is fixed. The RF output
signal is the up-converted RF signal.
"RF In/Out" RF output connector at the R&S FE44S.
"RF A"/"RF B"
RF output connectors at the R&S FE50DTR.

Frequency Band Configuration
Displays frequency band parameters of the external frontend.
Frequency Band Config ← Frequency Band Configuration
Define the intermediate frequency (input) range of the external frontend.
The used Intermediate Frequency and the resulting Frequency Band x are indicated for
reference.
