In this case the instrument must be equipped with
●
at least one baseband generator (option R&S SMU-B10) and
●
at least one baseband main module (option R&S SMU-B13).
Fading scenarios can be created with the aid of a fading module (option R&S SMU-B14,
Fading Simulator).

Externally generated I/Q signal
The I/Q signal is generated by an external instrument and coupled in via the baseband
input module (option R&S SMU-B17, Baseband Input). The baseband input module is
capable of processing analog I/Q signals. If options are installed for internal baseband
generation, external and internal baseband signals can be added (possibly with fre-
quency offset). In this operating mode, the fading module can also process external I/Q
signals.
