Enhanced QAM Modulator

Over view

QAM6210 is a prefessional, high quality digital headend transcoder. After the processing of RS encoding, scrambling, interleaving, QAM, wave filtering, finally upconvert frequency signal into RF signal and transmit out. With the advanced QAM modulation, It max supports up to 1024QAM, which greatly promote and optimise the RF output performance.Its service to make it widely applied in medium and small scale DVB-C headend network fields and hotel TV soultions.
