In the "I/Q settings >General" dialog, set "State > On" to enable the I/Q modulator.
7. Select "SGMA-GUI main panel > RF > On" or press the [RF ON] key on the front
panel of the instrument.
The [RF ON] key is green.
The I/Q modulated signal is output at the RF connector of the instrument.
How to generate an I/Q modulated signal with higher RF?
If the R&S SGS is equipped with one of the options R&S SGS-B112/B112V, you can
connect an extension, an R&S SGU, to it and thus extend the frequency range of the
generated I/Q signal up to 40 GHz.
Refer to Chapter 9.2, "How to Generate I/Q Signals with an R&S SGS and an R&S
SGU Upconverter", on page 149 for more information.
9.2 How to Generate I/Q Signals with an R&S SGS and an
R&S SGU Upconverter
Options R&S SGS-B112V and R&S SGU-B120V/-B140V are required for the I/Q mod-
ulation.
To generate an I/Q modulated signal with higher frequency
In this example, the R&S SGU acts as an extension to the R&S SGS extending its fre-
quency range to 40 GHz.
The Figure 9-2 shows an example of the test setup.
