Description: SFT3301 QAM modulator is a high performance modulator developed according to DVB-C (EN300429) standard which is the standard of the European broadband satellite telecommunication. It provides a more powerful receiving ability of various TS come from encoder, multiplexer, DVB gateway, scrambler and video server. In addition, the modulator also has the function of outputting RF, and simultaneously disposes the TS by RS encoding, convolution interlacing and QAM modulating. This device supports local and remote control through NMS software. For the field scope, it can be used for Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications. Quick Detail:
