Generating A Digitally Modulated Signal - R&S SMM100A Getting Started

®
R&S SMM100A
Connect RF of the R&S SMM100A to a signal analyzer, for example
®
R&S FSW, to display the generated signal.

Generating a Digitally Modulated Signal

This example shows you how to generate a simple WCDMA-3GPP (QPSK 45°
offset) signal with the help of the "Custom Digital Modulation" functionality.
The minimum requirement for R&S SMM100A in this example is a base unit
equipped with:
● Option baseband generator R&S SMM-B9
● Option custom digital modulation R&S SMM-K520
● Option frequency R&S SMM-B1006.
The initial situation is not the instrument's preset state but rather the configuration
described in Chapter 5.1, "Generating an Unmodulated
1. In the block diagram, select "Baseband" and navigate to the section "Misc >
Custom Digital Mod...".
