Description and purpose:

​

MDQ13-R QAM Modulator supports 4 channels TS input with optional ASI/DVB-C/DVB-S/DVB-S2 Tuner. It provides one channel tuner and 3 channel ASI inputs, which can multiplex the digital signals, come from satellite or cable and TS come from 3 channel ASI inputs. After multiplexing, the modulator will dispose output channel signals by RS encoding, convolution interlacing and QAM modulating. In addition, the modulator also has the function of real-time bit rate monitoring. Furthermore, this is a professional device integrated with TS multiplexer and digital QAM modulator, which can effectively reduce the system cost. User can also take it as a single digital QAM modulator when only ASI input selected.
