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
SMBV100B in this example is a base unit
equipped with:
●
Option custom digital modulation R&S
SMBVB-K520
●
Option frequency R&S
SMBVB-B103.
The initial situation is not the instrument's preset state but rather the configuration
described in
Chapter 5.1, "Generating an Unmodulated Carrier"
1. In the block diagram, select "Baseband" and navigate to the section "Misc >
Custom Digital Mod...".
The "Custom Digital Modulation" dialog opens.
2. In the "Custom Digital Modulation" dialog, select "General > Set according to
Standard > WCDMA-3GPP".
3. Select "General > State > On" to enable signal generation.
