How much do you know about the trigger function of an oscilloscope? (superior)

An oscilloscope is an Electronic measuring instrument that graphically displays a changing voltage signal, usually a two-dimensional image of one or more signals changing over time, and is known as the “eyes of an electronic engineer.” If you want to observe and Display oscilloscope waveforms stably, and capture characteristic signal events, triggering is the key factor. Therefore, a full understanding of the concept, principle and setting method of triggering is a prerequisite for effective use of an oscilloscope.

Since the birth of RIGOL more than 20 years ago, RIGOL oscilloscopes have also shifted from the original analog trigger to full digital trigger, and the trigger functions of the oscilloscope have been continuously enriched and enhanced. This article will explore the ins and outs of the “triggering” of the oscilloscope together with everyone-

01. What is trigger? What’s Trigger?

Triggering is to set certain conditions of voltage amplitude, time, waveform change rate, etc. according to requirements. When a certain waveform in the waveform data stream meets the set conditions, the oscilloscope will capture the waveform and its adjacent parts in real time and display them in ON the Screen. Only a stable trigger can have a stable display. Trigger is also the most important means to locate the problem after the problem is discovered. Good use of trigger can easily locate the signal you are looking for.

02. Two key factors of Trigger

The oscilloscope has gone through two main stages: analog oscilloscope and digital oscilloscope from its birth. The trigger system in the analog oscilloscope is a good starting point for understanding trigger related content. Then we start with the most important comparator circuit in the basic concept of analog triggering.

Single limit comparator

A simple comparator with only one reference level and a reference level of GND (0 level) is called a single-limit comparator. As shown below:

When the input signal of the single-limit comparator is greater than the reference level, the output is positive”
