DTA-2131 Features

  • Tuner, I/Q demodulator and sample-rate converter, optimized for use with SDR technology (Software Defined Radio = demodulation in software)
  • SDR enables advanced features such as full demodulation of DVB-T2 to T2-MI, or forwarding all IP packets from ATSC 3.0, or MER per OFDM carrier, transfer functions, etc.
  • Hardware sample rate converter for obtaining I/Q samples at a convenient sample rate
  • MER measurements in OFDM up to an accuracy of 42dB
  • Programming interface (DTAPI) is fully compatible with other DekTec adapters

DTA-2131 Applications

  • Network monitoring of ATSC, ATSC-3, DVB-T, DVB-T2, DAB+, DVB-C2 or ISDB-T with advanced measurements
  • Universal receiver
  • Receiving DVB-T2 as full T2MI stream
  • Recording of I/Q samples
  • Front end for SDR experiments
