FUTV4440B 4 in 1 QAM Modulator (Optional 4*ASI / 4*QAM / 4*DVB-S tuner / 4*DVB-S2 tuner Input, RF Output ) with NMS

R: V20150918-14-26 Data sheet   User Manual

 

Input:ASI, Tuner   Output:QAM, DVB-C  




Overview


FUTV4440B 4 in 1 QAM is a cost effective integrated QAM modulator newly designed by FMUSER Company. This device is integrated up to 4 channel QAM modulating carrier outputs, in which each carrier has independent signal channel encoding and direct RF output. Therefore, the device is featured with excellent RF performance index. It supports 4 channel ASI inputs (4 QAM (J.83 A/B/C), 4 DVB-S tuner input or 4 DVB-S2 tuner input). Alternatively, this device can take various RF inputs of DVB-S/DVB-C/DVB-S2 signals by installing the relevant build-in tuners. Hence, one PCS 4 in 1 QAM modulator can work as 4 standalone QAM modulators, significantly reducing the network operators’ head-end cost. FUTV4440B can also support local and remote control to set its working parameters.
