Product Overview
QPSK modulator supports ASI input to receive data of DVB transport stream from encoder, multiplexer, DVB gateway, scrambler, video server and other equipments, and then after RS coding, convolution interleaving and QPSK modulation channel processing, it gives RF DVB-S/QPSK signal output. It suits 1U rack and can be configured by front panel LCD and NMS (network management software) . Its high-integrated and cost-effective design makes it widely used in varieties of digital wireless broadcasting distribution systems .
