Abstract

The invention relates to a trigger system and a trigger method of an oscilloscope. The trigger system comprises an industrial control device, and a signal output device and a pulse output device which are connected with the industrial control device, and the signal output device is also connected with a pulse output device. The trigger system of the oscilloscope receives a tested signal through the signal output device, the tested signal is processed at the signal output device by adopting a first control parameter of the industrial control device to obtain a first signal and a second signal, and the first signal is directly output by the signal output device; the second signal is transmitted to a pulse output device and processed in the pulse output device through a second control parameter of the industrial control device, and the pulse output device outputs a pulse signal with a pulse waveform corresponding to the waveform needing to be captured; according to trigger data set according to requirements, the trigger system of the oscilloscope is used for processing a tested signal, so that a corresponding pulse waveform of slope trigger, pulse width trigger or under-amplitude trigger can be obtained.

Description

technical field [0001] The present application relates to the technical field of oscilloscopes, in particular to an oscilloscope trigger system and an oscilloscope trigger method. Background technique [0002] As a general-purpose electronic testing instrument, oscilloscopes are widely used in various industries. An oscilloscope that is easy to operate and has various functions can be favored by more users. The trigger function in the oscilloscope is one of the basic functions to ensure the user's use: the user defines the trigger event by setting the trigger condition and parameters, and the signal of interest will be captured and displayed on the screen stably. [0003] Existing oscilloscopes can only capture signals with simple trigger conditions. The signal waveforms for capturing trigger conditions include rising edge triggers, falling edge triggers, video triggers, and other trigger modes. For complex trigger modes (such as slope trigger, pulse width trigger, runt tri...
