The R.L. Drake model MEQ1000B is a commercial grade hybrid QAM modulator. The MEQ1000B features plug-in
input modules that include an ATSC/QAM tuner, Satellite L-band tuner, GigE IP input, an ASI input, a SDI/HD-SDI input,
HDMI (non-HDCP), Composite input, Component 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. This manual includes feature examples utilizing the Drake DTD1000A Digital Tuner and
Demodulator Module, IPI1000 GigE IP module, SDM1000 Satellite Tuner and the ASII ASI-Input Module. Other available
input modules include: SDE24A Dual SD MPEG Encoder, HDE24A High Definiton MPEG Encoder and SDI24A SDI/
HD-SDI Input Encoder. In addition, the MEQ1000B also supports older versions of these modules.
The MEQ1000B has two input module slots and the outputs interface to the MEQ1000B multiplexer, internally where
they are MPEG program filtered, multiplexed, and groomed. Programs among the total group from input Slot 1 and input
Slot 2 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: Channel Drop/Add, cherry picking programs from ASI or IP inputs, digital channel
processing, or local origination additions.
The MEQ1000B contains a high performance QAM modulator that can operate in most ITU-A or ITU-B modes up
through 256QAM. The very low noise, high output, up- converter 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 b 46
dBmV and + 61 dBmV.
The MEQ1000B operates in a fixed output clock mode and processes null packets when required to maintain the set
fixed clock rate. PCR correction is included.
