  • ATSC 3.0 gateway/modulator with control of all preamble-, subframe- and PLP parameters. Output directly in RF, or as I/Q samples.
  • Real-time IP input (ROUTE or MMT), offline input from an IP capture file (PCAP), or built-in PRBS generator for BER measurements.
  • Channel simulator for adding white noise and/or multipath echos (multiple fading models), for accurately simulating reflections.


  • Test-signal generator for the development and testing of ATSC 3.0 receivers, chip sets, televisions, monitoring equipment, etc.
  • Affordable and convenient way to experiment with or demonstrate any ATSC 3.0 feature, or organize field trials.
  • Generation of ATSC 3.0 I/Q samples for simulating system performance, for receiver algorithm development, etc.
