Outline
VEK-3403 is a high-performance modulator developed according to DVB-S2X (EN302 307-2) standard which is the standard of third generation of the European broadband satellite telecommunication. It is to convert the input ASI and IP signals alternatively into digital DVB-S/S2/S2X RF output.
BISS scrambling mode is inserted to this DVB-S2X modulator, which helps to safely distribute your programs. It is easy to reach local and remote control with NMS software and LCD in the front panel.
With its high cost-effective design, VEK-3403 DVB-S2X modulator is wildly used for broadcasting, interactive services, news gathering and other broadband satellite applications.
