Automatic trigger type identification method, device, and oscilloscope

An oscilloscope comprising a memory and a processor, wherein the memory is configured to store a program, and the processor is configured to execute the program to implement:

• acquiring a to-be-triggered signal from an analog-to-digital converter (ADC) of the oscilloscope;
• calculating characteristic parameter data of the to-be-triggered signal in real time, wherein the characteristic parameter data comprises at least one of bus protocol matching information or variation information of at least one characteristic parameter;
• determining a trigger type capable of stably triggering the to-be-triggered signal according to the characteristic parameter data;
• displaying the trigger type capable of stably triggering the to-be-triggered signal on a display;
• and
• causing the oscilloscope to select a trigger type to trigger the to-be-triggered signal based on the determined trigger type capable of stably triggering the to-be-triggered signal according to the characteristic parameter data.
