DekTec IP to QAM Quad Modulator

DTE-3114

The DTE-3114 is a stand alone, four channel QAM modulator, with TSoIP inputs that are directly synthesized to VHF/UHF outputs. The device is completely agile over all VHF/UHF frequencies up to 1000 MHZ and provides RTP with FEC decoding on each channel.

Sencore is the preferred distributor of DekTec in North America.

  • Stand alone four channel QAM modulator with TS-over-IP (TSoIP) inputs and directly synthesized VHF/UHF outputs
  • 2D FEC decoder for IP error correction
  • Web and SNMP interface for setting parameters and observing status
  • Unit can be powered via the Ethernet cable (Power over Ethernet) or through a DC power supply jack
  • Removal of IP jitter with programmable size of jitter tolerance buffer
  • Full support of SMPTE 2022-1/2
  • LCD status display shows device identifier, QAM mode, carrier frequencies, output level and IP/MAC address
  • Install up to 12 modules in 3U 19" rack space using DekTec rack mountable rail
  • Cable-TV modulator with TSoIP input
  • QAM test generator
