4 in 1 QAM Modulator

1.1 Outline

JXDH-6303-N All in1 QAM Modulator is a high performance device developed by ., integrate up to 4 routes QAM modulating carrier outputs, support 1-4 ASI inputs or DVB-S/DVB-S2/DVB-T standard RF input(optional by built-in tuner), after 1-4 separated encoding and modulating, then RF out directly in high performance.

Support local and remote control to adjust the device parameters, equal to 1-4 individual QAM modulators, so cost and space saved.
