Digital Transmodulators including:
  1. MDH-3000TM-10S Digital Cable TV QPSK to QAM Agile Transmodulator
  2. MDH-3000TM-10C Digital Cable TV QAM to QAM Agile Transmodulator
  3. MDH-3000TM-30S Digital Cable TV DS3/QPSK to QAM Agile Transmodulator with Ethernet port, DS3 option
  4. MDH-3000TM-30C Digital Cable TV DS3/QAM to QAM Agile Transmodulator with Ethernet port, DS3 option

MDH-3000TM-10S Digital Cable TV QPSK/QAM Agile Transmodulator
Features:
  • Both ASI input and SPI (LVDS) input
  • DVB-S QPSK Input as basic configuration
  • Automatically convert DVB-S symbol rate into DVB-C symbol rate
  • Empty package stuff function
  • 16, 32, 64, 128, 256 QAM Mode selectable
  • 1~7 MBauds Output Symbol Rate
  • Output full agile frequency (48~860MHz) digital RF signal
  • Adjustable RF output level by front panel control (100~113 dBuV)
  • User friendly operation interface through LCD monitor
  • Automatic last parameters memory
  • Store up to 99 channels of parameters

NOTE: The main difference between MDH-3000TM-10S & MDH-3000TM-10C is that in MDH-3000TM-10C, the QPSK tuner is replaced by QAM tuner.
