1. Load a standardized 3GPP downlink test model, e.g. "Test Model 1_16" and set
State to "ON".
2. Create a 3GPP Testmodel ARB file by activating "Generate Waveform File".
3. Setup a multi carrier scenario with 4 carriers and a carrier spacing of 5 MHz.
4. Apply the input file containing the previously generated 3GPP testmodel to all 4
carriers.
5.8.4 Multi Carrier Continuous Wave
The R&S SMJ can generate a Multi Carrier CW signal with user-definable offset from
carrier, based on a selection of up to 8192 unmodulated carriers. Each carrier can be
separately set and switched on, or multiple carriers can be jointly configured. Auto-
matic start phase setting is provided in order to minimize the crest factor.
Multi Carrier CW signals can be very easily configured as broadband test signals and
used for such purposes as receiver tests.
To access the dialog for setting a Multi Carrier CW signal, select "Baseband > Multi
Carrier CW" or use MENU key under "Baseband".
5.8.4.1 Multi Carrier CW User Interface
The "Multi Carrier CW" dialog is divided into the following sections.
The upper part of the menu is used for powering up the Multi Carrier CW and calling
the default settings.
The "Carrier Setup" section is used to configure the Multi Carrier CW signal.
The "Table Setup Assistant" section can be used to set a selectable carrier range.
