The training kit is based on a group of experimental cards that features different types of Helper communications blocks but in advance from the Electronics side perspective, to help understand some common communications blocks used in Analog and Digital Communication Experimental cards and measurements their parameters. The training system will guide students in learning the theory and practical aspects of communication circuits measurements such as Oscillators, Filters, PLL, ADC, DAC, Signal Sampling and Reconstruction, etc.

  • The training system is a comprehensive solution to teach Basic communications circuits via a wide range of experimental cards supplied with one or more card holders.
  • 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.
  • Communication 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 and also to ensure 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 11 Cards : Oscillators 1, Oscillators 2, PLL, ADC , DAC, Signal Sampling & Reconstruction , Filters 1, Filters 2, TDM Multiplexer, TDM Demultiplexer, FDM Multiplexing/Demultiplexing
