Radio Signal and Electromagnetic Interference Simulation System

Radio Signal and Electromagnetic Interference Simulation System is designed for generation and transmission, conductively or on the air, of required simulated radio signals and interference, as well as specific combination thereof.

Types of generated signals:„

  • Oscillation (harmonic, amplitude-modulated, frequency-modulated, frequency-modulated with linear frequency sweep, phase-modulated, amplitude-manipulated, binary phase-manipulated, binary frequency-manipulated, frequency-manipulated with linear frequency sweep);
  • „Noise (white, pink, Brownian, blue, violet, band, deterministic).

The system includes:

  • test signal simulation control and monitoring computer;
  • „test signal generation unit;
  • „unit for transmitting test signals to a higher frequency band;
  • „test signal amplifier.
