Which logical information, i.e. which stream, is output at which connector is defined by
the "IQ Stream Mapper".
For additional information, refer to Chapter 4.3, "Overview of the Input and Output Sig-
nals and Interfaces", on page 113 and Chapter 4.4.2, "I/Q Stream Mapper Settings",
on page 132.

Interdependencies
An I/Q modulation with an external analog signal cannot be used simultaneously in
the same signal path with the following:
●
AM, digital modulation, digital standards
●
Fading, noise
●
External digital baseband input signal, arbitrary waveform generation, and multi-
carrier CW.
7.3 I/Q Modulator Settings
Access:
1. To configure the input signal source of the I/Q modulator, select "I/Q Mod > I/Q Mod
In" and enable an internal baseband or an analog wideband input signal.
2. Select "I/Q Mod > I/Q Settings > I/Q Modulator".
