Problems solved by technology

For some signals, the more suitable trigger type is not edge trigger. However, the existing AUTO function can only be identified and configured for edge-triggered trigger types. Therefore, a new trigger type identification method is urgently needed.

Abstract

The embodiment of the invention provides a method and device for automatically identifying a trigger type and an oscilloscope, and belongs to the field of oscilloscopes. The method comprises the stepsof analyzing characteristic parameter data of a to-be-trigger signal, wherein the characteristic parameter data comprises change information of at least one characteristic parameter and / or bus protocol matching information; and obtaining the trigger type capable of stably triggering the to-be-triggered signal so as to allow a user to select or automatically select trigger. According to the methodfor identifying the trigger type, provided by the invention, the trigger type relatively suitable for the current to-be-triggered signal can be identified according to the change information of the at least one characteristic parameter of the to-be-triggered signal and / or the bus protocol matching information, and the to-be-triggered signal is further observed and tested very well.

Description

technical field [0001] The invention relates to the technical field of oscilloscopes, in particular to a method, device and oscilloscope for automatically identifying trigger types. Background technique [0002] The triggering of the oscilloscope means that the user sets the conditions according to the requirements. When a waveform in the oscilloscope sampling data stream meets the set conditions, the oscilloscope captures the waveform and its adjacent parts in real time. The conditions set by the user are called trigger conditions. The role of the trigger is to capture the event of interest and to stabilize the waveform display. Oscilloscopes have various trigger types, and the parameter setting process is also relatively complicated. This makes it impossible for users who are not familiar with oscilloscopes or have no operating experience to choose the trigger type reasonably according to the characteristics of the signal, resulting in more time-consuming signal debugging...
