DekTec XpressSim fading and AWGN simulator

DTC-305-CM XpressSim

Fading and AWGN Simulator

DTC-305-CM Features

  • Software option to add real-time channel simulation to the DTA-115 and DTU-215, and to other DekTec modulator cards
  • Addition of Additive White Gaussian Noise (AWGN) with well-defined SNR to the output of DekTec modulators
  • Distortions are applied in the digital domain for consistent operation and repeatability

 

  • Simulates up to 32 fading paths of either Constant Delay, Doppler, Rayleigh Jakes or Rayleigh Gaussian path distortion on the modulated RF signal
  • Simple interface to add calibrated noise to the output of a DekTec modulator card
  • Noise bandwidth is adjusted to suit the modulation type

Applications

  • Cost-effective evaluation of tuner and demodulator performance in R&D
  • Production test of tuner performance giving a fast, reliable and accurate method of ensuring quality control
  • Demonstration of the capabilities of tuner and demodulator chip sets

Minimum PC Requirements

  • Number of simultaneous fading paths that can be simulated depends on CPU performance
  • Windows XP, 2k3, Vista or Windows 7
  • Core 2 @ 2GHz, Core i5 or higher
* Or equivalent AMD processor
