•
Modulation (eligible parameter):
Select the constellation of the transmitted signal. The available options
are QPSK, 16 QAM, 64 QAM and 256 QAM.
• LDPC FEC (eligible parameter):
Select the FEC value for the transmitted signal. The available options
are 1/2, 3/5, 2/3, 3/4, 4/5 and 5/6.
•
FFT (eligible parameter):
Specify the FFT mode. The available options are 1K, 2K and 4K.
•
Pilot Pattern (reading parameter):
This field indicates the scattered pilot pattern used for the OFDM data
symbols. The available options are between PP1 and PP8.
•
Time Interleaving (editable parameter):
This option indicates the number of Time Interleaving Blocks (TI
blocks) per interleaving frame.
The user must select, in how many TI blocks an interleaving frame is
split.
Only the time interleaving mode 0 (TIME_IL_TYPE=0) is supported, so
one interleaving frame always equates to exactly one OFDM frame. To
deactivate the time interleaving, this parameter must be set to 0.
Press the OK button and then select the Up and Down buttons to
configure the desired value.
• TS Bitrate (reading parameter):
In this field it is displayed the bitrate of the transmitted signal according
to the modulation parameters used.
When editable parameters are being set in the Web Server and new
values are being introduced, the text remains in RED until the enter
button is pressed. When the enter button is pressed, the new values
are saved, and the text will appear in BLACK. It is necessary to press
the enter button to save the new values in the transmitter.
