Description
 
• High performance QAM modulator with 61 dBmV low noise agile upconverter.
• Economical multiplex of 2 ATSC format streams from dual ASI inputs.

The R. L. Drake model MQM861 is a professional quality, digital headend product that accepts one or two MPEG2 digital inputs via two Asynchronous Serial Input (ASI) connectors. These signals must be ATSC compatible streams if multiplexing is to be performed and usually will have originated from a local TV broadcast station and may have been transported over fiber links to the MQM861. After multiplexing and null packet management, the MQM861 QAM modulates and upconverts onto any desired CATV or off-air output channel between 54 and 860 MHz. The MQM861 can also operate as a non-multiplexing QAM modulator when a single ASI input is selected.
