1.1 Outline

The DEXIN NDS3402D DVB-S2 modulator (with BISS) 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 supports ASI or IP signal input and QPSK-S2 output. This DVB-S2 modulator supports local and remote control through NMS software. The NDS3402D DVB-S2 modulator (with BISS) can be used for broadcasting, interactive services, news gathering and other broadband satellite applications.
