9 Signal generator settings
This section summarizes the settings necessary to configure the instrument for signal
generation. The description in this section follows the menu tree structure of the graph-
ical user interface. Each of the discussed topics follows a common structure, providing
basic background information and reference to the user interface.
For step-by-step instructions for fulfilling typical tasks, refer to Chapter 11, "Performing
configuration tasks", on page 160.

9.1 Operation mode
You can operate the R&S SGS in two modes, normal mode and baseband bypass
mode. In baseband bypass mode, an external IF signal at the "I/Q In" connectors is
directly routed to the "RF 50Ω" connector. The level of the signal can be adjusted.
Refer to Figure 7-9 for visualization of the signal flow.
Access:
► Select "SGMA-GUI > Instrument Name > Operation Mode".

Sets the operation mode.
"Normal"
The complete signal processing chain is used.
"Baseband Bypass"
The IF signal fed in at the "I/Q In" connectors is directly routed to the
"RF 50Ω" connector.
Note: The "Baseband Bypass" is a special operation mode. See also
Chapter 11.3, "How to enable a baseband bypass mode",
on page 165.
