Page 9: Welcome To The R&S Smw-K550 Option
Accessing the Settings 2 Welcome to the R&S SMW-K550 Option The R&S SMW-K550 is a software option that allows you to duplicate generated base- band signals (streams) for specific system configurations. By that means, four base- band streams with real-time data sources can be generated in parallel. The generated... -

In particular, this includes: ● Managing settings and data lists, like storing and loading settings, creating and accessing data lists, or accessing files in a particular directory. -
Page 11: Stream Extender Related Settings
Stream Extender Related Settings R&S SMW-K550 3 Stream Extender Related Settings Duplicting streams is a feature that requires the additional option R&S SMW-K550. Access: 1. In the task bar R&S SMW, select the "System Configuration > System Configura- tion". 2. In the "Fading/Baseband Configuration" dialog, select "Mode > Advanced". - Page 12 Available are the standard settings and the following parameter, dedicated for the option R&S SMW-K550. Duplicate Streams ← System Configuration > Fading/Baseband Configuration (requires option R&S SMW-K550) This parameter is enabled in the configurations 3x1x1 and 4x1x1. In a 3x1x1 configuration for example, there are (per default) 3 basebands and 3 streams.

BS would then require two or more signal generators. Such setup can require extensive configurations and complex synchronization. In R&S SMW equipped with option R&S SMW-K550, the generation of 4 wanted and one interfering GSM signals is a straightforward solution. This section is a short intro- duction in the AM suppression testing. - Page 14 ® Application Example: GSM AM Suppression Test R&S SMW-K550 About the AM Suppression Testing Simplified test setup for base station receiver testing Figure 4-1 shows a simplified example of a test setup for AM suppression tests.
