Educational Electronics Training Kit Engineer Lab Equipment Teaching Device XK-SZDZ1 Digital Electronics Educational Equipment
1,System overview
XK-SZDZ1 Digital electronics training set can carry out experiment and practical teaching on digital electronics, electronic circuits, fundamentals of circuit and other related courses. The training set adopts modular structure, can be collocated flexibly according to different needs. The lower part of the test bed is equipped with four functional modules containing DC stabilized power supply, signal source and the required test instruments and meters. Experimental screen can be put into two sets of digital circuit multifunction test modules, to meet two students doing digital circuit experiments independently and easy operation.
