In case of two-path instruments, the analog I/Q output signal can be assigned either to
path A or path B.
The settings for the digital I/Q output signal are available for path A only.
I/Q Out - AWGN/IMP
Selects the path to which the I/Q output connectors are assigned (two-path instruments
only).
"Settings...."
Opens the submenu to set the output type and voltages, see chap-
ter 5.7.3.2, "Analog I/Q Output", on page 309.
The menu is only available when option Differential Outputs (R&S SMU-
B16) is fitted.
"I/Q Out from A"
The I/Q output connectors are assigned to Path A.
"I/Q Out from B"
The I/Q output connectors are assigned to Path B.

5.7.3.2 Analog I/Q Output
The differential output of the R&S Signal Generator provides symmetrical signals for dif-
ferential inputs of DUTs without the need of additional external electric network.
The operating point of the inputs can be set by a definable DC-voltage (bias). In addition
an offset between inverting and non-inverting output can be set to balance a difference
of the best operating points.
The differential output can be assigned either to Path A or Path B ("Impairment > I/Q
Out").
The equipment options for the basic unit (R&S SMU with frequency option R&S SMU-
B10x) include the option R&S SMU-B13 (Baseband Main Module) and the option R&S
SMU-B16 (Differential Output) for "I/Q Out...".
Option R&S SMU-B16 (Differential Outputs) cannot be fitted together with options R&S
SMU-B81/B82 (Rear Panel Connectors), because they use the same connectors.
