Code Rate
Configuration of the code rate of the output signals.
1/2, 2/3, 3/4, 5/6, 7/8
Constellation
Configuration of the constellation of the output signals.
QPSK, 16 QAM, 64 QAM
FFT Mode
Setting of the FFT mode of the output signals.
2K, 4K, 8K
Guard Interval
Setting of the guard interval of the output signals.
1/32, 1/16, 1/8, 1/4
Note
The output frequencies are always assigned to the forced adjacent channel in blocks of four. With individual pro-
gramming and activation of the output channels, the last activated channel is always the reference for the frequency
assignment.
Note Level assignment
-20 dBm = 89 dBµV
-15 dBm = 94 dBµV
-10 dBm = 99 dBµV
Attention
In the menu item "Modulator"
In the setting menu for the selected modulator
respective channel. The overall level at the output is reduced by 3 dB each time the activated output channels are
doubled compared to the individual output level.
Example
Single output level „Channel 1" - „Channel 4"
Total output level for 1 activated output channel
Total output level for 2 activated output channel
Total output level for 3 activated output channel
Total output level for 4 activated output channel
8.5 Menu "TS Config"
In this menu the configuration of the output transport streams will be done.
After clicking on "Output TS x" the selection list of the TS output channels 1-4 is displayed. By clicking on the desired
TS output channel, it is selected. The button "Stream Select" is used to assign the streams to the selected output
transport stream. To activate, please press the button, then the following menu window will open.
