4 Chnnel ASI MUX-Scrambler Modulator
Overview
4in 1 ASI QAM Modulator with Scrambler multiplexer is a cost effective integrated QAM modulator scrambler
multiplexer designed by SoChuang Company. This device support ASI input. And ASI signal has been sent to
signal processor after synchronized process. After Scrambling-multiplexing and modulation of the signal
processor, then 4RF output with 4 channels DVB-C directly. Therefore, the device is featured with excellent
RF performance index. Hence, one PCS 4 in 1 ASI QAM Modulator with Scrambler multiplexer can work as 4
stand alone scrambler QAM modulators, significantly reducing the network operators’ head-end cost. Also it
can support local and remote control to set its working parameters.
