MQM6000L Multiplexing QAM Modulator


Product Code: DRK-MQM6000L


The R.L. Drake model MQM6000L is a professional quality, digital headend modulator that accepts one to six single or multiprogram transport streams via six BNC, Asynchronous Serial Input (ASI) connectors. When six streams are input, the MQM6000L then multiplexes one program from each input and applies the result to the QAM modulator and up converter for output onto any desired CATV or off-air output channel between 54 and 1002 MHz. A program filter is provided to allow selection of the desired program from each input stream. Other programs in the incoming streams are dropped.

  • Front panel display and buttons allow easy setup and monitoring of operating mode and parameters.
  • +40 dBmV output, QAM modulator and very low phase noise agile upconverter are built in.
  • Output is agile on CATV or broadcast channels from 54 to 1002 MHz.
  • Six ASI Inputs.
  • TS Multiplexer for MPEG2 transport streams. Programs may be MPEG2 or H.264.
