Drake MEQ1000 Multiplexing Hybrid QAM Modulator

The R.L. Drake model MEQ1000 is a commercial grade hybrid QAM modulator. The MEQ1000 features plug in input modules that include an ATSC/QAM tuner, an ASI input, an IP input, and analog NTSC inputs; thus the description 'hybrid' is used to describe it. A multiplexer is built in to combine the transport streams and input the filtered and groomed transport stream to the QAM modulator.

The MEQ1000 has two input module slots and the outputs interface to the MEQ1000 multiplexer, internally, where they are MPEGprogram filtered, multiplexed, and groomed. Programs, among the total group from input module A and input module B, may be selected or not selected by the operator to be sent to the QAM modulator. Each input must contain no more than 20 programs and a maximum of 20 programs per input may be selected. Also, the total bitrate of the selected programs must not exceed that of the output QAM channel capacity. Some common applications include: drop/add, cherry picking programs from ASI or IP MPTS inputs, digital channel processing, or local origination additions.

The MEQ1000 contains a high performance QAM modulator that can operate in most ITU-A or ITU-B modes up through 1024 QAM. The very low noise, high output, upconverter provides coverage from 54 MHz to 1002 MHz while maintaining exceptionally low phase noise and broadband noise. Output level can be selected at a value between + 45 and + 61 dBmV. The MEQ1000 operates in a fixed output clock mode and processes null packets when required to maintain the set fixed clock rate. PCR correction is included.
