The training kit is based on a group of experimental cards that features different types of communications components and circuits to help teach the most common communications application and measurements and their parameters. The system demonstrates the principles of operation which most communication devices based on. The training system will guide students in learning the theory and practical aspects of communication circuits measurements such as AM modulator/demodulator, DSB-SC & SSB Modulator/ Demodulator, FM Modulator/Demodulator, etc..

  • Analog Communication Experimental Cards present techniques that modulate continuous carrier signals.
  • The training system is a comprehensive solution to teach communications circuits and applications via a wide range of experimental cards supplied with one or more card holder.
  • The system supports cascaded connection for the card holders by connecting up to three card holders in series. In other words, the output of one card holder is fed as input to the next one.
  • Communications circuits contained in each card are presented by their schematic diagrams and test points to learn about the circuit wiring and components and connect between terminals using safety cables.
  • Each circuit and terminal on the card are labeled for easy recognition and understanding of circuit elements and components also to assure more accurate and safe wiring during experimentation.
  • The system introduces the student to different types of communications concepts, and how to connect between components to apply certain functions and read different parameters.
  • This package includes 5 Cards: AM modulation/Demodulation, DSB-SC/SSB, FM Modulator, FM Demodulator, PWM Modulator/Demodulator.
