I am at the scene: "separated" to do experiments

"Classmates, the experiment begins!" Professor Wang Xinhuai made an order.

At this time, there was no student in the Electronics and Electronics Laboratory of Xi'an University of Electronic Science and Technology.

Wang Xinhuai explained to the reporter: "Affected by the epidemic, many courses have turned into online teaching. How to do experiments has become a problem. What you see now is the remote online smart experiment platform that the school has just built. Students pass remote access, so they will go, and then they will visit. You can control the equipment in the laboratory. "

Wiring, building circuits, building test points, starting experiments ... Sure enough, with the deepening of the experiment, on the dark screen of a oscilloscope in front of Wang Xinhuai, the yellow square wave and blue triangle wave began to change.

"In the past, online experiments were mostly calculated through virtual software. But with less practical exercises, the experience is not real enough, the learning effect will be greatly reduced. Now through the oscilloscope, you can turn the invisible electronic signals of the naked eye into visible waveforms. If the student We have major errors in the experiment. This system will automatically call the police to prevent the experiment from continuing ... You see, all the experimental data obtained in this way are real! " Experimental equipment express to the student's house, making it more convenient for students to do experiments! "
