Product Overview
YNS-3681Q is a new generation of modular & high density IPQAM. A single IP / modulation board has 2 IP inputs, multiplexing, scrambling and multi-channel modulation functions. The device supports up to 3 boards, 32-Channels IPQAM and 96 frequency points of modulation. This device adopts the latest module management function developed by Gospell, and configures the functions of device scrambling and modulation channels. Its flexible customization and strong expandability can meet customers' current and future digital TV systems. demand.
