HOME > Products > AV&Communication > DS303B The DS303B is a multi signal generator for terrestrial digital TV broadcasting. If assembled together with the optional units, it can output signals compatible with terrestrial digital TV broadcasting systems used in countries around the world, including GB20600-2006 (DTTB or DMB-TH) in China, ATSC in North America, DVB in Europe, and ISDB in Japan. Using an optional modulation methods, it can also output signals for different types of terrestrial digital broadcasting. This makes it possible to handle different broadcasting systems without the need to prepare different signal generators for different digital broadcasting systems. Features The DS303B is a multi signal generator for terrestrial digital broadcasting in worldwide. Supports multi terrestrial digital broadcasting systems.

Generates moving pictures, test pattern and user TS contents. Modulation unit Possible to switch between up to 8 different modulation methods. Up converter unit Generates RF signals in the VHF and UHF band. Noise signal can be added. (C/N 0.0 to 30.0 dB, 0.1 dB step) BER (Bit Error Rate) measurement is available. TS-Remux for ISDB-T system can be executed by external PC software. The features that any signal desired can be output any time, as necessary, can be put to effective use in cellular manufacturing on production lines.
