2. Select "ARB: Multi Carrier > Carrier Graph"
The carrier graph is a graphical representation of the current multi-carrier configu-
ration in the frequency domain.
The height of the bars corresponds to the gain of each individual carrier. The bars
width indicates the bandwidth of the carriers signals.
3.8.4 How to Use the Multi-Carrier Function
This section provides step-by-step instructions on how to configure and use the multi-
carrier settings.
To create a multi-carrier waveform file (general workflow)
Perform the following general steps:
1. To configure the general settings, select "Baseband > ARB > General"
2. To configure the carrier table select "ARB > Multi Carrier > Carrier Table"
3. To enter the filename of the multi-carrier waveform, select "ARB > Multi Carrier >
Output File"
4. To save and load multi-carrier waveform, select "ARB > Multi Carrier > Create or
Create and Load")
To generate a multicarrier signal for standard transmitter test
High power amplifiers of multi-carrier base stations face increased requirements in
terms of linearity and acceptable intermodulation performance.
To set up a standard transmitter test, proceed as follows:
1. Open the "Baseband > 3GPP FDD" dialog. Perform the following:
a) select "3GPP FDD > Basestations > Test Setups/Models"
b) select "3GPP FDD: Downlink/Test Model > Test_Model_1_16channels".
