DMB-5100 QAM Modulator is a powerful modulator, integrated with new ideas to meet the complicated market demand. It inputs QPSK signal directly (optional QAM/COFDM) and demodulate it into MPEG TS, then QAM modulate it into RF output; It can obtain MPEG TS from SDH network by DS3 adaptor, then QAM modulate it into RF output; Meanwhile, it supports multiplexing function, multiplexes ASI/SPI with all TS from various connectors, and modulates it into RF output, or output TS directly. DMB-5100 QAM Modulator not only meet the demand of broadcasting business economically and efficiently, but also ensure the promoting of advanced business in the future.
