Oscilloscopes allow you to visualize how electrical signals change over time. This means you can measure periodic and transient signals, which might be too fast for your digital multimeter to catch. Oscilloscopes can be indispensable for debugging circuits.
In the video, I talk about why 10x probes are useful, how to tune the compensation capacitor in a 10x probe, how to measure periodic signals, and how to set up a single capture trigger for a transient signal. I hope that this works as a starting place for someone who might be just beginning with oscilloscopes.
I here 10 min before my test keep posted to know how I do
You said we only needed to use one or two knobs.... but then you turned them all. You made my brain hurt. I'm not giving up regardless. Though my brain be small, my will is gigantic. This still makes my brain hurt though. I think I mentioned that.
Chris Norton
It is only when the brain hurts that knowledge is being applied.
When I was studying Electronics Engineering decades ago, whilst working for PHILIPS,
My direct boss and mentor made my head hurt.
I could have strangled him then.
Years later whilst serving in the Military, I asked him why he was so tough.
He explained it this way.
Knowledge is like hammering a nail into a wall.
To make sure it penetrates one has to hammer it hard.
When one just 'casually throw the nail (knowledge) at the wall, it will bounce off.
I realized that by being tough and a pain sometimes, he did me a great favor, in that
I never forgot what he taught me, and by doing so made me a great Engineer.
Ultimately leading to being posted as an exchange officer to the USAF, and having the
opportunity to work on some special projects, in electronic weapons, robotics projects for NASA/UASF
working with avionics specialists on the Presidents Jet(s), and having learned much during this time,
as well as solving some specific problems.
Stay with it. Success is achieved by 'DOING'. Trying does nothing, trying does not even cure constipation.
It will only give you pain the A _ _
As a side note .. I am still good friends with my one time mentor and former boss.
He is still alive and exceeded age 85.
Yeah this was at the 4:45 mark or so. I saw your comment first so when he did the setup before taking a measurement (pushing every button and choosing a setting for everything I barely grasp) I laughed out loud.
mee too man
I could watch this 1000 times and not be able to remember everything to explain it.
This is by far the best oscilloscope instructional video. The instruction was very clearly explained and covered all the bases to get up and running to diagnose equipment. Thank you for making this video!
Scopes are a must for debugging effectively and not just throwing parts at an issue. Great video!!
I don't know how Shawn does it, but his videos are _always_ exceptionally clear, and very information dense!
This is one of the better oscilloscope tutorials I have seen. Very detailed and concise, extremely clear, I intend on saving it and watching it again. Thank you.
I like people like this. Tell you information and not talk like they know it all or put things down or try to say you must buy this to get the job done.
Great video, love the humour whilst still maintaining a high level of useful and important information; a big thumbs up from me, subscribed and saved to watch again at a later date after I’ve bought my first oscilloscope! Many thanks!
Thank you for this video. It's literally the best scope tutorial on youtube, and I've watched loads of them over the last few days
This is a perfect video. Extremely informative and easy to follow. Ive just bought a new OS and you have filled in many of the gaps in my knowledge with this one video. Nice job. Thank you very much. 😎
It would be helpful if you could give practical examples of WHY one would need to use an oscilloscope. I’ve seen many videos telling me what oscilloscopes measure, and how the machine can be dialled in to take these measurements, but I still don’t understand what kind of circuit problems or situations require an oscilloscope.
Excellent presentation. Nice commentary, clear audio, high quality video, and very practical short to the point demonstration. Great work. I liked your video. Thank you for educating.
The last 5 seconds and the smirk did it for me. Thanks.
A very instructional and well produced video on using oscilloscopes
This is a very informative tutorial, especially the part on probes. It's also very well produced.
True, it is pretty dense and I admit I can't absorb everything in but one viewing.
But Shawn is very precise and exceptionally clear, so the trick (at least for me) is to watch the video repeatedly until I'm satisfied I've learned everything I can.
And if I have any questions, I can always ask my friend Google!
Thanks for a great lesson.
Thanks for the clear explanation. I'm not sure I caught every detail on tuning the capacitor for 10x operation but I learned a lot anyway.
So well put together. Clear, rich, interesting, straight to the point. Thank you 😃
Doesn't get any better at teaching than this video. Excellent.
This is the best tutorial video. Really helped me understand what each function means
it is nice to see that Tucker from "Something About Mary" was able to move on and do something with his life
awesome! all important basics neatly packed in 1 video
This is going to be very useful as I've just bought and old 'scope. Thank-you... and now I find you do lots of interesting products, cool!
Haven't had to use one in years. We were cleaning out clutter from my job, and boss was going to toss one. I asked if I could have it, and here I am brushing up on my basics. Mainly want to use it as a display piece on a shelf with my audio output connected for a cool frequency display. But will likely use it for more.
What is this thing for?
Thanks a millioon for taking the time. I am a rookie and learned a lot. I wanted to use my digi scope for stepper motor work.
Great video. Also props to the bowtie and and love the background/set too. Mise en scene aside, very informative and well presented. I had a scope in high school and had no idea how to make it work. I wish I had hung onto it. Looking to add one to my workshop.
I studied electrical engineering in college but worked outside my field after graduating. I'm looking to go back now after 5 years and you brought back so much buried knowledge. Thank you
Do you nake any money doing so?😀
Really appreciate your videos. They are clear and to the point. Keep up the good work!
Thanks! Glad you like them :)
Wonderfully clear and well-structured, good speed, only few concepts not defined
The best desciption ever about an oscilloscope
This is an simple to the point video.....new subscriber.....hope you have videos like this on capacitors too.
Excellent Tutorial , THANKS !
This guys videos are the best!
Perfect video, just what I needed, being new to scoping!
Very informative I've always wanted one and this vid certainly explains things keeping it to a good level
Brilliant, Thanks OP!
Howdy.
The 10X feature is to enable measuring high voltages or to provide very low loading of the measured circuit.
Tuning the probe capacitor means that the probe R/Xc ratio is the same as the input R/Xc ratio. This delivers best signal fidelity.
Using an oscilloscope be aware that the signal grounds are galvanically bonded. One could introduce short circuiting when using both channels doing measurements in an appliance. Worse still. Older cathode ray scopes also have their signal grounds connected to the chassis and the power Protective Eath ( = power ground ) is also connected to the chassis. There are real dangers to smoke one's appliance or getting shocked.
Always feed an older scope through a separation transformer. Always use a galvanic separator in one channel when doing dual channel measurements.
In my digital scope there are galvanic connections between the power ground ( = Protective Earth ) and the input grounds. However. I use the scope in an older apartment where there are only two prong outlets in the room. Old wiring may, totally legally, be as they were done originally. So I do not need to feed the scope through a separation transformer.

Looks legit.

I never play around with electronics without my bow tie.
Bowties are cool.
@@polymetric2614 I caught that reference ;)
@@robertturner4913 since i made that comment i also have gathered additional evidence that bowties are cool: michael from the good place wears one
A great scope tutorial so far! Thanks!
Glad you like it, thank you!
This is a great 101 Oscilloscope video. Thank you!
the last seconds are the best part!!
Great video. Thank you for making time and share with us.
I was looking for a good video on how to use an oscilloscope. Then I found this . I think it's informative. And the last words were funny - " If you want to do some sciency.....whenever somebody walks by... all you gotta do is just measure a sine wave " :D
thanks, i found one at the side of the road and it WORKS thanks for the video!!
Nice and clear explanation. Thank you very much Shawn.
excellent production
Glad that they didnt scare off any newbies with the fact that the scope shares ground on all channels and that ground is not isolated from the rest of the circuit in your house so if you go probing AC voltage and connect your ground to live or neutral you gonna have a really bad day.
Most excellently done, just the right combo of pragmatics & KISS, perfect for me. I'm on the east coast of the US. So tomorrow I will bow humbly in your westward general direction. Weird well yes, but it's a geek/nerd physicist tradition/thing. Thks again
Fantastic work, and made simple to understand
I like this. Making tech talk cool my dude. Very nice.
Fantastic and very well explained. Thanks a lot for this nice tutorial.
Great Video, I am new to using a scope, and this is probably the best explanation / tutorial I have seen. Thank you!
Easy to assemble, good strong materials, feels good, looks good.
I needed this. Thanks
Great tutorial!
nice job! very good video, right to the point.
Thank you. That is the scope I am about to buy, so this tutorial was credibly helpful. Well presented as well.
Nice job guys! Alan Lowne
Thank you very much. It is nice guide for me (I am a little bit skilled, but bought an oscilloscope for the first time).
Nice and simple explanation of the basic functions. Good work.
Thank you, glad you liked it.
It is very good informative tutorial. I use similar scope for my hobby and it really helped me to find sources of weird behavior or my circuits - without it I would be clueless. Even knowing already how to use the scope I learned bits of new things from this video. Thank you!
Awesome! Glad it helped :)
Stanislaw Pak lol me 2
Do you make any money doing so?
Excellent and up to date. Thank you.🌹
it's so much fun, big fan of Shawn
Great video! Thank you.
This was very helpful! Thanks!
Thanks for this, it was very helpful. I have several analog Tektronix scopes and could make them sing and dance. I think the newest one is over thirty years old. I just bought my first digital scope and was lost. Actually, it seems to be too automatic. I just wasn't ready for a "plug and play" scope. You gave me better and more information than the manufacturer documentation. Now, I'm off and running.
yeah first using a digital scope is insane.
Professional instruction great job.
great tutorial, thanks
Very useful tutorial. I've never been taught how to use a digital oscilloscope works. Now I can go start up a scope in the school lab and do something useful instead of fooling around with nonsense signals :)
Great video, a bit goofy but quick to the point and informative.
This was very helpful thank you
Very good and helpful video; thank you!
Thank you, thank you, thank you! I really needed this. I was baffled about certain things. Or I incorrectly considered certain things like the 10:1 probe. When 10x means attenuation.
Very good teaching!!
Great tutorial, thanks :)
thank you
from Morocco
wow, this is exactly what I've been looking for!!
I wish I watched this about 8 hours ago :(
very good video, many thanks
Excellent video. Thank you very much.
Great video!
Good, informative video!
I could have used this info 50 years ago. But I had to learn everything the old-fashioned way, by getting shocked.
These waves are also used to make sound on old 8-bit Gaming Systems.
0:14 You totally look like a first wave artist from the '80s that my mom woulda listened to religiously. I guess we are dealing with signal synthesis Lol
Thanks for the useful info.
I bought a scope just so I can look like I'm doing something sciency.
Always a good call.
Yea? Me too! (LOL). Frankly, I bought it because I need to test and adjust my Tascam 32 Reel to Reel Record and Playback heads. I've got a lonnnngggg way to go before I can do that. So I joined a forum and I printed out 3 different "How-To" manuals and one owners manual.
Now I need to lock my home-office door for two hours everyday because my wife doesn't seem to understand that periodical intrusions while I'm reading these manuals requires my utmost concentration. I always wanted to learn how to use a scope but I've NEVER EVER touched or 'played' with one! I only recently realized that I wasn't near an oscilloscope more than maybe twice in my 60+years!
That's really wild in my mind because I'm a retired 1st class machinist and have worked for at least 15 different production shops, job shops, mold and tool-making shops and even 3 or 4 specialty R&D shops! (Not to mention a number of journeyman field jobs I was hired to do). At least two or three of those shops were geared to machine electronics related parts and equipment.
I may have seen a scope in the R&D shops, (one was an aerospace shop and two others were 'extreme-compression' operations). It just seems weird to me that as interested as I've always been about oscilloscopes, and the potentiality of one or more of those shops to have a scope, I've hardly ever even touched one... huh...
Well now, I own one... "hmm let's see, where the on/off switch on this thing..."
FWIW
Ahahah! i liked" the wife intrusion section!!"
I bought a load of books n shelves, and got rid of my T.V. to look more intelligent.
I'm a former B-707 and DC-8 driver and have made the mistake of exploring micro-electronics. I'm single so the wifey thing isn't gonna be a problem but the endless reading of manuals isn't my thing either. That's like engaging the auto-pilot and just scanning the steam gauges (or worse today, the glass screen cockpit displays now standard on flight decks...) and doing nothing but twiddling my thumbs for 6+ hours.
At least with a radar (doppler) scope I could see what was important and know what it is. With these things, I'm beginning to think I need an EE PhD to understand them :) Good luck with the manuals and the wifey separation time. LOL
Fills in a few details on digital scopes. Thanks!
This was very helpful.
nicely explained.
Hobbyist and appreciate a refresh. Thanks
Just bought a real digital scope, pulled this video up, ..... glazed over about half way through.... "uhhh let's watch it again." This is so much more powerful than I thought!
Great Video Thanks
My college just threw out about 30 brand new ones and I grabbed a few cuz I thought they looked cool thanks for telling me what they do :)
Where??
Abhijeet D.Srivastava my school
lucky lol
Phenomenal video! That really helped me understand the use of a scope! Thank you!
Excellent. Thank you.
This is a very interesting subject. I may not understand it, but at least I know about it.
Two thumbs up to you sir. Great tutorial.
Thanks!
Very informative video, thanks!
Two things:
1) How would you get from buying the SparkFun MiniGen kit to using it to test a scope? There seems to be some steps missing between having the MiniGen attached to a Pro Mini and actually having a setup that allows you to choose wave forms etc. (blue selector button and pot in the video)
2) What kind of software are you using to draw diagrams in the video? Are you using a pen or just a finger/mouse? Connected to a Wacom tablet?
This is by far the best beginner tutorial out there!
Thanks, glad you like it!
I've used scopes for years, but never knew what some things were for. Now I have a much better grasp of things - in particular, the 10x probe setting.
A few days ago I bought E-design's DS203 Mini Oscilloscope for digital oscilloscope. Not bad.
