7.6. Data Slice and PLP Parameters
The DSlice parameter tab allows you to specify the Data Slice parameters and the PLP parameters.
The light coloured rows specify the parameters of the Data Slices. Each Data Slice can contain zero,
one or more PLPs. The parameters of the PLPs within a Data Slice are specified in the slightly darker
coloured rows below the Data Slice parameters.
7.6.1. Data Slice Parameters
Each light coloured row specifies the parameters for a Data Slice.
Data Slice parameter Description
DSlice ID Unique identification of a Data Slice within a C2 system
Const. Config Indication whether the Data Slice configuration is variable or fixed. If
checked, the configuration is constant. This parameter is only used in
combination with Data Slice Type 2.
Type Data Slice Type: Data Slice Type1 or Data Slice Type 2
Tune position Tuning position of the Data Slice relative to the start frequency (DVB-C2
general parameter) specified in multiples of the pilot carrier spacing.
Offset left Start position of the Data Slice by means of the distance to the left from the
tuning position specified in multiples of the pilot carrier spacing.
Note: Offset left may have negative or positive values.
Offset right End position of the Data Slice by means of the distance to the right from the
tuning position specified in multiples of the pilot carrier spacing.
Tune/Left/Right This field gives an outline on the Data Slice tuning in MHz.
FEC header FECFrame header type: Robust mode or High efficiency mode
Left Notch Indication whether a left neighboured Notch band is present. If checked, the
start of the Data Slice is neighboured by a Notch band.
TI depth The time interleaving depth within the Data Slice: No time interleaving, 4, 8
or 16 OFDM symbols
To add more Data Slices, right-click the mouse in the Data Slice and PLP parameter area and select:
Insert Data Slice. Alternatively, the Insert key can be used.
To remove a Data Slice, select the Data Slice then right-click the mouse and select: Remove Data
Slice. The shortcut key in this case is Delete.
To navigate through the Data Slice parameters, use the arrow keys. After selection you can press the
Enter key to modify the parameter. When done, press the Enter key for further navigation.
7.6.2. PLP Parameters
