DTA-110T Features

  • DVB-T modulator / DVB-H modulator fully supports EN 300 744
  • ISDB-T and DTMB modulation options
  • NEW: ATSC modulation option
  • Low cost, low power and flexibility is achieved by performing part of the OFDM modulation process in software
  • Supports DTA-110 modes: QAM-A/B/C

 

  • Integrated UHF Upconverter with on-board 400…862-MHz synthesiser
  • RF output can be connected directly to a DVB-T terrestrial receiver
  • Programming interface (DTAPI) compatible with other DekTec digital-video output adapters
  • With DtLoop: DVB-T modulator replacement
  • PCI rev 2.2, 32 bit, 33 or 66 MHz bus

DTA-110T Applications

  • Driving DVB-T / ISDB-T / DTMB receivers or
    DVB-H handhelds for demos, at shows, in electronics stores
  • Set-top-box development, repair, production testing, performance testing
  • Signal validation: check out whether your receivers can handle a new transport stream
  • Output adapter for generating a modulated
    RF signal directly from your custom application

PC Requirements

  • PC selection is critical because of software processing. The DTA-110T will not operate well in PCs that lack sufficient CPU power, memory- or PCI bandwidth
  • P4@2GHz minimum, or equivalent AMD
  • 512 MB RAM minimum
  • SDK for Windows-2000/XP/2003 and Linux
