Description

Technical Field

[0001] The utility model relates to the technical field of oscilloscope devices. Background Art

[0002] An oscilloscope is an electronic measuring instrument with a wide range of uses. It can transform invisible electrical signals into visible images, making it easier for people to study the changing processes of various electrical phenomena. The oscilloscope uses a narrow electron beam composed of high-speed electrons to hit a screen coated with fluorescent material to produce tiny light spots (this is the working principle of a traditional analog oscilloscope). Under the action of the measured signal, the electron beam is like the tip of a pen, which can draw a curve of the instantaneous value of the measured signal on the screen. The oscilloscope can be used to observe the waveform curves of various signal amplitudes changing over time, and it can also be used to test various electrical quantities, such as voltage, current, frequency, phase difference, amplitude modulation, etc.

[0003] The existing handheld oscilloscopes are small in size and easy to carry. However, the handheld oscilloscopes are only wrapped with a rubber cover for protection. First, the rubber cover is directly attached to the handheld oscilloscope. Therefore, when it is dropped or collided, sharp and hard objects can pass through the rubber cover and collide with the handheld oscilloscope, causing damage to the handheld oscilloscope. Second, the rubber cover cannot completely isolate the buttons on the handheld oscilloscope from the palm. In hot weather or high-temperature areas, when people use the handheld oscilloscope outdoors, the sweat on their hands can easily flow into the inside of the handheld oscilloscope through the gaps between the buttons, causing damage to the handheld oscilloscope. Therefore, a device that can completely wrap the handheld oscilloscope is needed. Utility Model Content
