Outline
YDS3402E is a high-performance modulator developed according to DVB-S2 (EN302307) standard which is the standard of second generation of the European broadband satellite telecommunication. It is to convert the input satellite signal and/or ASI and IP streams into digital DVB-S/S2 RF output.
BISS scrambling mode is inserted to this DVB-S2 modulator, which helps to safely distribute your programs. It is easy to reach local and remote control with Web-server NMS software and LCD in the front panel.
With its high cost-effective design, YDS3402E DVB-S2 modulator is wildly used for broadcasting, interactive services, news gathering and other broadband satellite applications.
