a) Select the "SGMA-GUI main panel > Instrument Name > I/Q settings > Analog
Impairments"
b) Enable I/Q impairments.
c) Enable the I/Q modulator: In the "I/Q settings > General" dialog, set "State >
On".
7. To activate the RF output, you have two options:
● Select "SGMA-GUI main panel > RF > On"
● On the front panel of the instrument, press the [RF ON] key.
The [RF ON] key is green.
The I/Q modulated signal is output at the RF connector of the instrument.
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 R&S SGU as an extension. This extension also extends the frequency
range of the generated I/Q signal to up to 40 GHz.
See Chapter 11.2, "How to generate I/Q signals", on page 162.
11.2 How to generate I/Q signals
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 11-2 shows an example of the test setup.
