DMB-9550 DVB-S2 Modulator adopts advanced baseband processing and up-conversion technology. Conforming to DVB-S2 EN302 307 and EN300 421 standards, it accepts ASI and IP signals, supports BISS scrambling (BISS 0, BISS 1, BISS E), and SFN function with MIP/IIP packet optional. It outputs high quality RF signals (output frequency range of 950~2150MHz), has perfect automatic protection mechanism and function of redundancy backup, and supports centralized management of NMS network management software. These make the device widely applied to constructions of DVB-S/S2 digital broadcast system and has become one of the most popular satellite DTV core equipments.
