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.

Main Features:

Support 8 ASI inputs, support CBR and VBRSupport ITU-T J.83A/B/C, output frequency range: 30 MHz ~ 860 MHzExpandable up to four RF modulating output (GQ-3650DS optional)Support two E3/DS3 inputs and two ES/DS3 loop outputs (GQ-3650E optional)Support PID filtering, pass-through, PCR auto-correction4 adjacent frequency output with output-channel selection switch88/204 self-adaptive packet length with real-time input data format displayExtremly large buffer design, support both burst & uniform input streams, and also support re-uniforming of the input data, in order to improve the output efficiencyModulated transport streams can be either directly passed through, multiplexed or scrambledNIT mapping & forwarding up to 45 frequencies8 groups of PID filtering and re-mappingSupport various customizable PSI/SI table extraction, resolving and modificationSupport SI table information replacement and insertionSelf-adaptive filter circuit design ensures outstanding out-of-band rejectionCentralized Web, SNMP(GQ-3650DS) management and remote upgrade / maintenanceSupport monitoring of operation temperature and power supply status
