The rear panel provides a third TRIGGER INPUT / OUTPUT connector, see chap-
ter 3.2.2.10, "TRIGGER 3 INPUT/ OUTPUT", on page 56.
3.2.1.15 EXT MIXER Connector (optional)
External mixers can be connected at the EXT MIXER LO OUT/IF IN and IF IN female
connectors to increase the available frequency range. This connector is optional and
only available with R&S FSW-B21.
If no external mixers are connected to the R&S FSW, cover the two front connectors
LO OUT / IF IN and IF IN with the supplied SMA caps.
3.2.1.16
RF INPUT 50 Ω
A device under test (DUT) can be connected to the R&S FSW to provide RF input
which is then analyzed. The DUT is connected to the instrument's RF INPUT via a
cable equipped with an appropriate connector.
Risk of instrument damage
Do not overload the input. For maximum allowed values, see the data sheet. For AC-
coupling, a DC input voltage of 50 V must never be exceeded. For DC-coupling, DC
voltage must not be applied at the input. In both cases, noncompliance will destroy the
input mixers.

This figure shows the rear panel view of the R&S FSW. The individual elements are
described in more detail in the subsequent sections.
