4 Signal Routing and System Configuration
The R&S SMW provides multiple routing possibilities and simplifies the definition of
versatile MIMO configurations.
Provided the instrument is equipped with the required options, R&S SMW can:
●
Process the internally generated digital baseband signal
●
Process an external digital signal
●
Generate vector-modulated baseband signals, irrespectively of the signal source
●
Impair, add noise, and apply fading to digital baseband signals.
Generally, the processing of the generated baseband signal involves a modulation on
the selected radio frequency (RF) and output at the RF connectors. However, the digi-
tal baseband signal can also be output directly, or converted and output as an analog
I/Q signal.
To support you in your configuration tasks, the R&S SMW provides the "System Con-
figuration" dialog. The main focus of this section is the "System Configuration" settings.
This section also introduces the concept of the signal routing possibilities and covers
the settings provided for the adjustment of the input and output analog and digital sig-
nals.
The information in the following sections assumes a fully equipped R&S SMW.
4.1 How the System Configuration Function Supports
You in Your Task
The R&S SMW vector signal generator is an instrument with outstanding characteris-
tics that can serve a wide rage of test cases. Irrespective of your current use case, the
decision process on how to fulfill the task with the R&S SMW and what kind of configu-
rations are necessary, undergoes the same main phases.
The "System Configuration" settings and capabilities support the decision and the con-
figurations in these main phases. It helps you for instance to define MIMO configura-
tions, to route the signal thought the instrument, and to connect and control external
instruments.
