3.2 Connecting the R&S SMW
This chapter provides step-by-step descriptions for connecting the R&S SMW with
components and instruments of a bandwidth extension setup. Connecting procedures
for relevant connector types are summarized. Connecting to these connector types is
analogous for all other external frontends. The step-by-step descriptions cover the fol-
lowing topics:

To connect a power combiner
The following procedure describes how to connect R&S SMW to a power combiner.
Also, it describes how to connect the power combiner and a directional coupler. The
R&S SMW is switched on and connected to power.
For prerequisites of the power combiner, see
1. Use high-quality RF cables.
See "Cable selection and electromagnetic interference (EMI)" in the R&S SMW
Getting Started.
2. Use short RF cables for connection between R&S SMW and power combiner.
3. For correct operation, use one of the following combiner kits:
●
●
4. Establish the RF connections.
Steps (d) and following of the step-by-step description assume a connection to an
R&S SMW-ZKV combiner kit. Connecting other power combiners is analogous.
a) Ensure that the RF connector of the R&S SMW is compatible with the RF con-
b) Inspect the RF connectors carefully. Look for metal particles, contaminants and

If an RF connector is damaged, do not proceed, because the risk of damaging
the mating connector is too high.
