Digital QPSK Modulator for DVB-S

DMB-9500 QPSK modulator is a high-performance QPSK modulator which is fully DVB-compliant, and already operational worldwide in satellite up-link applications.As self-contained, standalone unit, it can operate completely independently within the Digital Video Distribution system.At the same time, it also can be used in MMDS microware point to point transmission system, DMB-9500 QPSK modulator is ideally suited to remote control and monitoring by system software, and easy to use in redundant configurations in association with IF switching (e.g. by using contact closures).
