GQ-3650DS
 
Multifunction QAM Modulator
 
     GOSPELL GQ-3650DS can receive MPEG-2 transport streams from 8 ASI inputs and 2 E3/DS3 inputs (optional for GQ-3650E), and then multiplexing, scrambling and processing it with channel coding, finally output 4 channels of adjacent RF signals after QAM modulation, GQ-3650DS/GQ-3650E is our economical core product of digital cable TV head end solutions. Users can get these functions upon their system needs and budgets by purchasing the update package from the suppliers.
