This trainer should be a classic analog circuit training system which should be suitable for experiment teaching courses such as 'Analog electronics technique' and 'Electronic circuit'
It should adopt a portable box-type design with an aluminum profile frame, easy to carry for flexible teaching purposes.
Various experiments are to be performed by using basic unit circuits with external components or other unit circuits, all the schematic diagrams are printed on the front panel for clear identification
With a two-layer design structure, an extended circuit board can be mounted easily on the basic panel to build a variety of experiment content while saving space.
The basic service area should come with a DC power source, DC signal source, function generator, digital frequency meter, digital DC voltmeter, etc.
The open experiment area should be provided with multiple IC sockets and electronic component insertion sockets to achieve various experiment extension and course design.
