To connect a three-port mixer
External mixers can be connected at the LO OUT/IF IN and IF IN female connectors (if
option is installed). 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.
