Description Additional Product Specs Extended Information
 
The R. L. Drake model DQT861 is a professional quality, digital headend transcoder product that tunes and demodulates MPEG2 digital VSB or QAM modulated signals from an off-air broadcast or CATV source or accepts an ASI input source. After error correction, it remodulates and upconverts the recovered MPEG2 transport stream onto a new QAM modulated digital output channel.
Features
  • Front panel backlit display and buttons allow easy setup and monitoring of operating mode and parameters.
  • High output, 61 dBmV, agile QAM modulator and upconverter are built in, operating up to 1024QAM.
  • RS232 serial interface provides for remote control programming and monitoring.
  • The field installable ASI input or second tuner/demodulator modules (if not factory installed) add the transport stream multiplexing function.
  • Input tuner/demodulator(s) tune off-air or CATV channels between 54 and 860 MHz and provide demodulation of 8VSB, 16VSB, or QAM modes from 16QAM to 256QAM. ATSC, ITUA (DVB), or ITUB (DigiCipher® II) FEC modes are supported.
  • A wide range equalizer suppresses multipath effects on ATSC signals.
  • Off-air ATSC mode incorporates a NTSC co-channel rejection filter.
  • Major channel number pass through or remarking to RF output channel is selectable.
  • Operates in a fixed output clock mode and processes null packets when required to maintain the set fixed clock rate.
  • Program filtering allows the user to select which MPEG programs present in the input streams are to be included in the output or discarded.
  • PSIP options include several modes of operation.
  • MPEG program numbers and minor channel numbers of input B or the ASI input may be offset to prevent duplication of the input A numbering.
  • Rewriting of the MPEG tables is provided when two input streams are multiplexed.
  • PCR restamping is performed when necessary.
  • 61 dBmV QAM low phase noise output is agile on CATV or broadcast channels from 54 to 860 MHz.
  • High MER output signal quality.
  • Meets or exceeds DOCSIS 2.0 Downstream output specifications.
  • 1U tall package with internal power supply conserves rack space.
  • Manufactured in the USA.
