Abstract
By way of the development to the school numeral experiments an AEDK- DEC1, analyze the problem of the existing experiment equipments existence: Lead the line contact not dependable; Be short of the breadboard, can't imitate the experiment; The continuous pulse signal source frequency undue lead high;Nil numeral voltmeter etc…The experiment box that improves the empress will make up these weaknesses, can make it satisfy the request that now experiment, even can develop the student's active and the unique.
The basis existing experiment box is a template, taking into the design to the total layout of the experiment box, making the combination that each parts can moderate been together, still increasing the all-powerful chip electric outlet and the breadboard specially in the design moreover, toing occupy the very big space in whole layout, each position of parts of appropriate processing, among them mainly include the power supply part of place the rationality of the choice in order to in experiment, two power supplies lead to the burden center area, to reduce the line high-frequency interference.
Keyword:The numeral experiments the development of the box, total design, breadboard, numeral voltmeter.
