C channel output such as S21 (306 MHz). It is recommended to stick to the corresponding
TV standard channel spacing and symbol rate (6900/6960).
QAM Constellation Mode
•
Different QAM constellation(16, 32, 64, 128, 256) can be selected. Higher constellation offers higher capacity. QAM 256 is recommend-

If not all 4 output channels are to be assigned, each channel can be switched off individually if needed.
ATT (Adjust) Output Channel
•
The output level can be individually weakened in 1dB steps.
LCN (Logical Channel Numbering)
•
The allocation of a logical channel number (LCN) is a service that dedicates a serial number to each TV activated program. LCN should
be operated before assigning a service to an output channel.
