Product Overview
The NDS6656 48/64-carrier IP TO RF (DVB-T/ATSC/ISDBT/DVB-C) modulator is an all-in-one multiplexing modulator developed by our company. It has 48/64 multiplexing channels, 128 scrambling channels and 128 QAM (only 128 channels with scrambling in DVB-C mode) modulation channels, supports up to 512x2 IP inputs through 8 data ports, and 48 non-adjacent carriers through 4 RF output ports (50MHz~960MHz) outputs. The device has dual RF output ports to widen the bandwidth of QAM carriers.
