An overview,

"JXSM - type 2 the actual analog electronic technology experiment platform" is combined with the current development trend of electronic technology experiment, experiment box maintenance for aluminum alloy, easy to go bad, process the general characteristics, research and development of new electronic technology experiment box, can finish the virtual simulation electronic technology, virtual instrument using now for the development of electronic technology, the modular design, the new design at the same time the regulated power supply, all digital design, greatly improves the reliability and efficiency.

Technology configuration

* 1. The experimental platform is designed with a full range of molds and has a beautiful appearance. It is made of high-quality PVC and black engineering plastics. Leave virtual oscilloscope, virtual signal source interface, power interface, I/O interface and other common interfaces. Each bin can hold four modules at once.

The 2 modules are made of 2mm thick printed circuit board, with the graphic symbols of components and corresponding wiring printed on the front and the printed circuit printed on the back, and the related components and so on welded. Easy maintenance. High quality galvanized pole can be used to complete circuit power supply. Single tube common emitter amplifier, negative feedback amplifier, differential amplifier, operational amplifier circuit, RC sinusoidal oscillation circuit, provide: MOSFET amplifier circuit, photoelectric coupling linear amplifier circuit, integrated operational amplifier, LC oscillator and frequency selective amplifier circuit

3. The experiment box shall be equipped with voltage regulator power supply required for the experiment. Voltage regulator power supply (configuration shall not be less than ±5V/ 0.5a, ±12V/ 0.5a and voltage adjustment range 0 ~ 18V/1A;) , all digital design, with communication interface and full network data monitoring function, provide cloud tools such as LABVIEW and mobile APP software, with short circuit protection and automatic recovery.

4. One ac transformer (2-way 8V/ 0.3a with fuse protection)

5. Provide experimental instruction and other teaching resources. The wires have different colors.
