Oscilloscope Triggering Techniques:- how to trigger a scope

Ғылым және технология

One of the key controls for any oscilloscope is the trigger control. Knowing how to trigger an oscilloscope properly enables the best images of the waveforms to be seen on the scope screen. In this way it is possible to properly see what is happening in any circuit and this helps locating and faults and issues. It helps, in electronics development, service, repair and within education.
This video explains what the oscilloscope trigger is and how it works. It details the basic functions and shows the effect of the controls on the scope triggering.
There are two main controls for basic scope triggering. The level or threshold and the slope. Changing the threshold or trigger level changes the point at which the signal triggers the scope to display the waveform. The slope determines whether the oscilloscope should trigger when the waveform is on the positive or negative going slope.
The video also discusses some of the more advanced forms of triggering available on many oscilloscopes. These include triggering on pulses, waveform trains and even packets of data.
Finally the video gives some key tips on how to trigger a scope. Everything from using the external trigger input to making sure the trigger signal is steady and free from noise.

    If one wants to synchronize two oscilloscopes, would it be better to use the auxiliary trigger input or an analog input channel?

    Let's say I have displayed an input signal (of an ac system or whatever) and afterwards I also display the output signal. Does the triggering the phase difference between the two signals? If so, Why?

    Whats the difference between these 3 - Normal - Scan - auto..- Im familiar with "single", as that, will wait for input before almost taking a screendump , but these 3 other trigger modes look like the same- thx for the video.

    What is the difference between before and after triggering on my DSO oscilloscope. The square wave looks identical either side of the trigger? There is a memory display of the record length at the top of the screen that shows a trigger and how much of the record length is displayed on the screen. I can scroll indefinitely in one direction in this record length box but only to the end of the record in the other direction. It is a Rigol scope

    The various formats for trigger can help in some situations where there are complicated waveforms, or a particular part of the waveform needs to be monitored. In many cases it will to make a difference.

    I am sorry but we cannot provide advice on individual scopes and how they work. I suggest that you contact the manufacturer directly - they should know.

    thanks for reply.i understand that each scope has different feature.have you ever captured multiple trigger on single channel?if yes than kindly share how.may be I get some idea about the scope which I am using

    I think you have to come back with more information on triggering , I still do not understand how to use the trigger and what exactly it means …

    Yes, I seem to remember I had a bad cold at the time and was under pressure to get the videos out, so I had to go with it. :-)

    So what a waste of time. Where's the info about AC triggering ?

    Sorry to hear you didn't find the video useful. We try to do the best we can, but obviously don't always hit the mark for everyone.
