It is possible to import/export the pre-correction data and this makes it simpler to move the pre-correction settings
to other modulators that use the same settings. This can be accessed by the gear icon and seen in the screenshot
above.
8.4.8 DVB-T2 OUTPUT MODULE
For DVB-T2 output modules, the Port Settings tab is shown below:
Modulator
RF level measured in dBmV
Currently tuned frequency in MHz
Bandwidth of the currently tuned channel
Enables continuous wave signal ( For test only).
Shows the current effective bitrate of the output port
The available configuration parameters in the GUI will not be documented in detail. The parameters are according
to the DVB-T2 specification, ETSI EN 302 755 v. 1.2.1 (2010-10). The configuration of a DVB-T2 transmitter requires
a good working knowledge of this specification as well as the DVB-T2 implementation guidelines, ETSI TS 102 831.
Chapters 4 through 6 of the implementation guidelines is a good place to start with regard to a high level
understanding of the parameters involved.
The user interface attempts to verify that the chosen combination of parameters is valid. Invalid entries will be
highlighted in red and “Apply” will not work unless errors have been corrected.
The “FEC blocks” and “Bitrate” are status parameters that indicate the expected payload carrying capacity of the
chosen parameters.
