Harris Offers QAM Demodulator
Harris Corp. has added QAM (quadrature amplitude modulation) capabilities to the company's Videotek DDM-800 digital demodulator. The feature allows demodulation of both 64 QAM and 256 QAM signals in support of both cable and terrestrial digital television requirements.
The DDM-800 converts QAM signals to DVB-ASI. The demodulated MPEG-2 streams then can be decoded and muxed or passed on to a cable television facility via QAM modulators.
"The cable market presents many opportunities for us, and enhancements such as this recent addition to our demodulator line will help us stay ahead of the competition and provide our customers with added value," said Tim Thorsteinson, president-elect of Harris Broadcast Communications Division.
The DDM-800 is supplied as a 1 RU package and can accommodate up to three additional demodulator units.
The Harris Videotek division has been producing television demodulators for more than three decades and provides a full range of models for applications ranging from simple off-air monitoring to FCC proof-of-performance measurements.
