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.

Features

• 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.

• ATSC PSIP is supported.

• MPEG program and minor channel number offsetting when multiplexing.

• Major channel number pass through or remarking is selectable when multiplexing.

• Rewriting of the MPEG tables is provided when two input streams are multiplexed.

• PCR correction is performed when necessary.

• RS232 remote control and monitoring capability with the included Drake Digital
Headend Control Software.

• High MER output signal quality.

• 1U tall package with internal power supply conserves rack space.

• Manufactured in the USA.
