●Multi-functional QAM Modulator
●GQ-3650E

Multi-functional QAM modulator GQ-3650E is a QAM modulator with multi-channel inputs and multi-frequency outputs. It is able to receive TS from ASI or E3/DS3 (optional) inputs. The input TS can be passed-through/multiplexed and QAM modulated and output as RF signal, with 1 RF test output.

Main Features:

·Supported modulation modes: 16/32/64/128/256QAM
·Support ITU-T J.83 Annex A/B modulation with pass-through, multiplexing and scrambling output
·RF output frequency range: 30MHz~900MHz
·Internal extra-large buffer design supports both burst and uniform input TS with re-uniform of TS
·NIT mapping and forwarding of up to 45 frequencies
·Support 8 groups of PID filtering and mapping
·Customizable PSI/SI table retrieving, extraction and modification, with support of SI table replacement and insertion
·Support input data null packet filtering and output data filling
·Precise PCR correction of multiple PCRs in the input data separately
·Track filter circuit design ensures outstanding out-of-band rejection
