Method and apparatus for decoding oscilloscope signal and oscilloscope

An oscilloscope, comprising:

• at least one processor;
• and
• a memory communicably connected to the at least one processor, wherein
• the memory stores instructions that may be executed by the at least one processor and that, when executed by the at least one processor, cause the at least one processor to execute the steps of:
• obtaining a voltage signal from a measured device;
• converting the voltage signal into a digital signal;
• determining whether the digital signal matches a decoding protocol;
• and
• when the digital signal matches the decoding protocol, decoding the digital signal according to the decoding protocol into an image, and displaying the image for observation by an end-user;
• wherein the determining whether the digital signal matches a decoding protocol comprises:
• determining at least one data frame in the digital signal according to a format of a digital frame of the decoding protocol;
• checking each of the at least one data frame;
• and
• determining whether each data frame is checked successfully
• when each data frame is checked successfully, the digital signal matching the decoding protocol is determined.
