How to Use Trigger Types on a Digital Oscilloscope - Workbench Wednesdays

A powerful, but underused feature of digital oscilloscopes is the trigger circuit. Learn from James how to use an oscilloscope’s trigger to find glitches, measure pulse widths, see transients, and stabilize a scope’s screen. This video explains the difference between Auto and Normal sweep modes, shows how to use a Pulse Width trigger, and explains how to use Hold-Off bit.ly/3yKeziE

at 0 second, you can see James pauses and smiles for the start of the shooting. Thank you for your hard work and excellent quality of your videos.

James I absolutely LOVE the Workbench Wednesdays. Each one of them contains neat tips that everyone has "heard about" but isn't too certain about. As a student, I've found them exceptionally useful in giving me more tool confidence. Keep it up!

[@MaxWattage]

Great video, well presented. I especially liked the explanation of the nuances of hold-off time.

[@ronaldschild157]

Yes, a "very modern" counter @3:07 indeed. 😂

[@wb7ond]

Yeah, the nixie tubes were a "give away"... I almost spit my coffee... Great video by the way

[@anthonycalia1317]

Nice Job explaining this

[@klausfortschbeck8369]

Great video James. Keep on doing

[@bald_engineer]

Thank you Klaus!

[@mikheilbeldishevski2776]

Thanks

I would love to know your recommendation for the best quality scope an advanced hobbyist could shoot for. I've decided that I want 4 channels and probably 200MHz but there are names I run across when searching for such a scope that I don’t know much about such as Siglent, Rigol, Hantek, and Owon. Are any of these brands that you would steer clear of? If you were on a budget and could not afford the expensive brands such as the Rohde and Schwarz, what would be likely to look at? Thanks.

I don’t even know if my Hantek 6022bl even has a trigger, I have heck of a lot to learn. Now I’m retired I’ve plenty to keep my mind occupied. I’m definitely going to try the Arduino thing but with the cheap east oscilloscope outside the kits I’m not holding my breath.

@@stiaankruger2699 Thank you very much for the info and your encouraging words, it’s genuinely appreciated.

[@markharrisllb]

@@stiaankruger2699 It’s not so much my budget as much as it’s a hobby to keep the brain working. I’m a boomer and I retired last Monday but I’ve made sure I have enough hobbies to keep me learning. Thanks again.

[@lezbriddon]

i have a 1980s analog no buffer no memory crt scope with a reliable very stable trigger, for christmas i treat myself to a hantek dso2c15 with a trigger choice of none or random guess mode.... at least i kept the old faithful

[@jstro-hobbytech]

you're a great teacher. you're bench gear is worth more than a home where I live hahaha

[@shadimurwi7170]

Android smartphone is amazing good job Sir

[@johnnguyen8508]

thanks for not explaining scopes like your audience are fools, but now I know I am a fool

Anyone else triggered by this video?

[@GwynDelight]

I normally love element14presents content. However, teaching on a Rohde & Schwarz oscilloscope that few of us will ever be able to buy or afford is pretentious, entitled and arrogant. Teaching on equipment the average person can afford makes much more sense for a channel like this. Please keep that in mind in the future. Additionally, teaching using equipment the average person can afford leads to greater levels if interest in your feed.

[@Gengh13]

There really isn't much of a difference in Rigol or Siglent scopes.

[@bald_engineer]

Models from Multicomp Pro and Digilent were also shown in the video.

You are talking too fast, this is not an advertisement 😊
