Problems solved by technology

[0002] At present, in many fields, electronic instruments are required to work outdoors or even in many harsh environments for a long time. Although at the beginning of the design of the instrument, there are many targeted designs in terms of hardware for the different environments it is suitable for, however, in the outdoor environment Incidents of instrument damage caused by natural or human factors also occur from time to time. Due to the lack of commonly used electronic instrument testing equipment such as oscilloscopes and signal generators, it is not convenient to carry out real-time detection of them.
