Overview


MDS01 DVB-S (QPSK) Modulator is a high performance modulator developed according to DVB-S (EN300421) standard which is the digital video broadcasting standard of European satellite telecommunication system. This modulator adopts the advanced channel coding technology and it has powerful receiving ability. Besides, the RF output of this modulator is in L wave band, so it can be directly connected to the digital TV transmitter of satellite telecommunication system. MDS01 DVB-S modulator can be used for Broadcasting, Interactive Services, News Gathering and other satellite broadcasting applications.
