Frame Length
The Frame Length parameter sets the DVB-S2 modulation frame length.
NOTE:
This parameter is only relevant for units operating under DVB-S2 modulation scheme.
This parameter is not available in the DVB-S module (default value is 32 Kbits).
This is a dynamic value screen and displays various available values according to the selected
modulation scheme. The available options are:
The selected value sets the frame length to the selected number in bits (for example, selecting
64,800 sets the frame length to 64,800 bits.
