DVB-S2 Uplink Modulator With 32APSK COL5502N

COL5502N 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 ASI and IP signals alternatively 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 NMS software and LCD in the front panel. With its high cost-effective design, COL5502N DVB-S2 modulator is wildly used for broadcasting, interactive services, news gathering and other broadband satellite applications.
