This teaching system consists of 2 learning boards on the subject of communication technology.
The modulation board illustrates the most common analogue and digital modulation methods. In this way, you can teach learners the basics of communication technology.
The Demodulation Board is an extension of the Modulation Board. This learning board contains all the important demodulators.
All output signals of the Modulation Board can be demodulated with the Demodulation Board. Due to a well thought-out concept, the preparation time for experiments can be reduced to a maximum.
Note: The matching experiment instructions must be ordered separately.
Our products are designed for the European market and meet CE requirements. For international use, regional regulations apply which must be observed. The usability of the products shown must therefore be checked in advance.

Mechanical specifications
The front panel of the training board is made of 5 mm thick laminate, colour matt blue, and is engraved with white switching symbols corresponding to the built-in function groups. A sturdy plastic cover protects the rear of the unit and, due to its shape, allows it to be placed at an angle on the table to suit the work.
