To connect a three-port mixer
External mixers can be connected at the LO OUT/IF IN and IF IN female connectors
(option R&S FSW-B21). Both two-port and three-port mixers can be used. Connect the
mixer as follows:
Use the supplied coaxial cable to feed in the LO signal. If no external mixers are con-
nected to the R&S FSW, cover the two front connectors LO OUT / IF IN and IF IN with
the SMA caps supplied.
1.
Connect the LO OUT / IF IN output of the R&S FSW to the LO port of the external
mixer.
2.
Connect the IF IN input of the R&S FSW to the IF port of the external mixer.
3. Feed the signal to be measured to the RF input of the external mixer.
