HY-21-QAM64 64 Channel QAM Multiplexing and Scrambling IP Modulator


Description

HY-21-QAM64 64 in 1 IP QAM modulator is a Multiplexing-scrambling-modulating all-in-one device developed by GHCOMTEK. It has 64 multiplexing channels, 64 scrambling channels and 64 QAM (DVB-C) modulating channels, and supports maximum 512 IP inputs through the 4 data ports and 64 non-adjacent carriers (50MHz~960MHz) output through 2 RF output interfaces. The device is characterized with dual RF output ports which broaden the bandwidth for QAM carriers.
