DNQ-3 is a Digital Video Broadcast-Cable (DVB-C) TV QAM 49~750MHz Agile modulator. The QAM modulation could be chosen among 16, 32, 64, 128 and 256 level numbers. DNQ-3 also has the package stuffing function for low rate stream input. DNQ-3 has LED monitor and front panel key pad for easy operation, and it is suitable for 19'' rack with 1U height. It is the most economical and the most efficient choice for up-grading the current CATV systems, MUDS systems and MMDS systems.
