3.9 How to Connect External Instruments and Configure
the Signal Flow
This section gives examples on the following topics:
●
How to select the required system configuration and to configure the signal flow
through the instrument
●
How to connect external instruments to the R&S SMW and how to configure them
●
How to define the input and output signals.
General workflow
The general workflow described in "General workflow for finding out the suitable sys-
tem configuration for a current use case" on page 123. The Figure 3-14 is a graphical
representation of this workflow.
The graphic depicts the main phases for connecting and configuring the R&S SMW
and the external instruments. This illustration is a simplified diagram that highlights the
configuration stages performed in the "System Configuration" dialog.
For relevant information on the configuration of the baseband source signal or using
the fading simulator and the AWGN generator, see:

Chapter 4, "Configuring the Internal Baseband Source", on page 220
●
Chapter 3.6, "Digital Baseband Input Settings", on page 170

Figure 3-14: General configuration stages and the steps performed in the System Configuration dia-
log
The illustration depicts the steps in general and is intended to explain the configuration
in principle.
