Example: IF and frequency band configuration for R&S SMW-B1006 and
R&S FE44S
The example shows the IF value for IF low frequency band configuration:
●
"Intermediate Frequency > 4.12 GHz": Frequency of the IF signal for IF low mode
("Frequency Band Config > HWS")
●
"Active RF Connector > RF Out": RF output connector at R&S FE44S
●
"Frequency Band 1 > 24.00 GHz ... 44.00": Frequency range of the RF output sig-
nal
To work with R&S FE50DTR Simultaneous RX/TX connection mode
The following procedure describes how to activate and work with "Simultaneous
RX/TX" connection mode of the R&S
FE50DTR external frontend. This connection
mode requires a test setup consisting of a signal generator, an R&S FE50DTR and a
signal analyzer. Table 3-3 shows a connection example using R&S SMW and
R&S FSV/A.

For a test setup, see Figure 3-2 .
1. Select "RF A/RF B" > "RF Frontend" > "Frontend Device".
2. Select "Connection Mode > Simultaneous RX/TX".
3. Wait until the R&S SMW establishes a lock at the connected R&S FE50DTR.
