Features

  • Supports all constellations and modulation modes for each supported standard in VHF, UHF and L-band.
  • Excellent signal quality through direct digital synthesis of the RF output signal and an on-board ultra-low phase noise oscillator.
  • Can be used for wide-band advanced modulation schemes, such as 16-MHz multi-segment ISDB-Tmm, DVB-S2X and 64-MHz DVB-C2 channel bonding.

Applications

  • High-end general-purpose test modulator in your R&D lab for developing and qualifying DTV equipment, or for experimentation with new RF modulation schemes.
  • Automatic test equipment (ATE) for tuners, demodulator chips, receivers, TV sets etc.
  • Play-back of arbitrary I/Q sample files that are recorded or pre-computed (e.g. with MATLAB), with a bandwidth up to 72-MHz.

Block Diagram

The DTA-2115 reads data from the PCI Express bus and forwards it to a baseband modulator, a channel filter, an optional channel simulator and an upconverter. The digital RF signal is converted to analog with a high-speed D-to-A converter and output on a main and monitor output.
