6. FEF Parameters

This area allows you to insert and specify the Future Extension Frame settings.
7. AUX Streams Parameters

This area allows you to insert additional dummy auxiliary streams.
8. Frequencies

This area allows you to set the carrier frequency. In case of Time-Frequency Slicing (TFS) you can set

multiple frequencies.
9. Output Settings

This area allows you to specify the name, location, size and the format for the generated signals.
10. PLP Parameters

This area allows you to specify the parameters for each PLP and to select the Transport Stream

source for each PLP.
11. PAPR Parameters

This area allows you to specify the Peak-to-Average-Power-Ratio (PAPR) reduction parameters.
12. TX Signature

This area allows you to specify the transmitter signature in the FEF part and AUX streams.
13. Channel Fading

This area allows you to add noise to the output signal and to specify multiple simulated fading

paths. For each path you can specify the channel-simulation parameters.
14. Messages

In this area interesting events are shown.
15. Status Bar

The status bar shows the validity of the DVB-T2 parameter set.

5.3. Multiple Component Signal Generation
T2Xpress allows the generation of a DVB-T2 signal containing two components, one component

using the T2-base profile and another component using the T2-lite profile. Checking the Multiple

Component check box enables this option. In case this option is enabled, the T2Xpress user interface

allows you to specify for each component:

- General DVB-T2 parameters

- Frame parameters

- Test Points parameters

- FEF parameters,

- AUX Stream parameters

- PLP parameters

- PAPR parameters

- TX Signature parameters


Note that the components have to use the same bandwidth. Multiple component T2-MI output is not

yet supported.
