Novel high-frequency electronic circuit experiment box and operation method thereof

Abstract

The invention provides a novel high-frequency electronic circuit experiment box. A USB data communication interface, a power supply interface and a power indicating lamp are arranged on one side wallof a box type casing, a signal source interface, an oscilloscope interface and a multimeter interface are sequentially arranged on the other symmetric side wall, and an inverted integrated circuit board is arranged on the opening surface of the casing; a row main socket interface, a nut and a row pin are arranged on the upper surface of the integrated circuit board, and an MCU (microprogrammed control unit), an A / D conversion module and a DA converter are arranged on the lower surface of the integrated circuit board. The invention also provides an operation method of the novel high-frequency electronic circuit experiment box. The experiment box integrates the oscilloscope, a signal source, an adjustable power supply, programmable digital IO, digital input / output and the multimeter interface, can be combined with a matched high-frequency electronic circuit experiment board for multiple circuit experiments, realizes various tests on the high-frequency electronic circuit experiment boardand is particularly suitable to be used as a teaching aid to assist teachers and students in teaching or learning in electronic circuit experiment courses of colleges and universities.

Description

technical field [0001] The invention relates to the technical field of teaching experiment boxes, in particular to a novel high-frequency electronic circuit experiment box and its operating method. Background technique [0002] The electronic circuit course is a theoretical and practical professional basic course for electrical engineering and electronics majors, and the electronic circuit experiment course is an important teaching method and approach. At present, the basic structure of the general electronic circuit experiment box is made of aluminum profile or ABS plastic. The box is equipped with a simple DC power supply and a simple function signal generator. The box is made of a unit circuit experiment area made of copper-clad board. Each experimental unit in the experimental area is equipped with an appropriate amount of test jacks. However, there are many defects in this experimental box in actual use. And it has not been fundamentally improved for a long time. The ...

However, there are many defects in this experimental box in actual use

And it has not been fundamentally improved for a long time. The structure of the simulation experiment box provided by each manufacturer is basically the same, which is difficult to meet the current higher quality teaching needs.

The main problems are: (1) the current analog electronic circuit experiment box is too large, occupying too much laboratory space, and it is not easy to carry; (2) there are few external interfaces of the experiment box, generally only oscilloscope and digital The test function that can be realized by the multimeter is relatively simple, and it is difficult to complete more circuit test experiments. If the test box is equipped with more test interfaces, the test box will be larger and occupy more space.
