In this tutorial I used the ISO-TECH IDS 6072A-U oscilloscope and a bench power supply to demonstrate how you can use the single shot feature with triggering to capture a signal event / glitch / transient. I also the demonstrate the use of the cursor feature to measure a signal.

I do appreciate your videos. I bet just like tons os people are waiting for this series to continue. Thank you.
Exactly what I was looking for, funny that over 50% of the time I always end on your channel! :-)
Thanks for sharing all this great knowledge and videos with us!
Great series. Just "captured" my home built dc power supply rise event. Thanks for being patient and explaining the basics, you give me confidence using my first scope a Siglent SDS1202X-E 200 mhz
I am a novice at the oscope and was having a lot of trouble trying to capture a single event and this video was perfect. After capturing it a few times, I noticed that I wasn't capturing what happened AFTER the sudden rise of voltage during an event (a cap charging) so I used triggering on the "down slope" in addition to the single event mode and bang, I got the whole thing. Thanks for making the difficult concepts of using the oscope and particularly triggering easier to understand. As you said, it is an iterative process of looking at what you are getting to set the horiz and vert scales properly.
Great video, Martin. Please continue the oscilloscope series. One of my favorite channels.
Omar Assaggaf My pleasure Omar, thanks for the post. More to come and on spectrum analyzers.
@@mjlorton I can't find video about acquiring signal as you mentioned at the end of video? In which video did you mention about acquiring signal? Thanks for the great video
Another great tutorial video. I bought my scope in connection with a project involving an LVDT and measurements at the micron level. So the quality of the voltage inputs to the LVDT and the S/N ratio of its output will be one of the first things I will use the scope to assess, along with measuring the effects of signal conditioner alternatives. Also, I have a momentary button that produces bounce, and I will be using it to assess the timing on that so that I can implement anti-bounce code for the microcontroller to insure it is eliminated. And the information you've provided in this video should enable me to accomplish those objectives. I can't wait to see the next on in your series now ! Thanks again !!
I found this video very educational! Even though my Siglent SDS1102CML oscilloscope isn't exactly set up the same exact way I was still able to find the settings. And most importantly understand what each setting was for. It really helps to have the oscilloscope in front of you at the same time watching these videos. I learned what the triggering is for and how it's used. Thank you very much!! :-)
thanks again Martin, you are a very good teacher, little by little you are helping me to learn to use my new scope. keep'em comin!
Thanks a tons mate! This is great instructional videos for oscilloscopes. Your videos are top notch Martin
It's 2:34 a.m. and I am eating these videos! Great work and the simplest explanations
Thanks Martin. I've used a scope for awhile at my job but never had to use some of these features. Very helpful.
My pleasure Robert...and yes...some sensitive electronics may not like an overshoot like that.
Thanks for the post.
I am a retired programmer and have been playing around and learning robotics using the raspberry pi and Arduino like micro computers (as can be seen on my TH-cam channel “LotBot Robotics”. I have been using servos and software that produces Pulse Width Modulation without really understanding pwm. So I thought I would get an oscilloscope to see if I can really learn what pwm is and how it really affects a servo. I have spent a lot of time looking at videos on the oscilloscope and was still very confused when I happened to see your videos. I just had to thank you for creating videos that give a novice a good understanding of an oscilloscope and it looks like other equipment that I plan to review in the future. Again thank you very much for spending the time an effort to create great educational material.
Very nicely done. Smple, easy to follow examples that others can do alongside with their own scope while watching the video.
your videos have saved my ass! (4 years after you posted them!) I have an exam tomorrow on oscilloscope function and my professor is horrible at explaining... thank you for the videos.
Legend! I had to do an electronics module at university for my computer science degree and let me just say that your explanations are far superior.
Thanks! Gave me the ability to get started quickly with this oscilloscope!
Huge Thank's for your thorough explination of these procedures, your explinations from the basic principles is superb, and huge help A++++
Very good...the best I've seen regarding triggering.
Martin great set of video's using the oscilloscope, content really useful and love the use of your analogies; thumbs up. Kind Regards Bob (UK)
Martin - You're the man!
Great series!!! Really appreciate the professionalism and quality of the video and its content. Being new to electronics repair this is a great jump start vs researching the User manual. Thank you and keep them coming.
Thanks for your nicely paced lessons - just right for a beginner in oscilloscopes like me.
This tutorial really saved me! Thanks a lot!
Thanks for your feedback.
Great comparison to the camera analogy.....Thanks, as usual a Great Video !
Thanks man, quite helpful and clear to understand.
Well described thank you, now capturing wave forms no problem!
Great presentation, very useful information I can apply to my bench work. Thanks
This was awesome 🖤
Great video, just what I needed very helpful.
thank you for the great video with all the information i needed. :)
thanks man! It's been really useful
Thanks Martin,
I don't really use long time base sweeps, mostly a few ms or so, recently though I had to use a time base of 5s per div. I couldn't think why my scope couldn't single sweep. Your information answered this. As my display is 18 squares across the trigger sweep took a lot of time to produce.
Altering the trigger point to the second vertical Graticule and a trigger level of around 800mv, gave me the signal I was looking for.
I've used scopes for years but never had to address this situation.
My Scope is a Siglent SDS1102CML and I love it. Great price at £275.
I would love for you to be able to do a review on it.
I hope your financial situation improves, I like your content. It would be a big loss to lose you.
wonderful! explanation about single trigger...
Hey dude, you are really incredible.. Thank you very much for this beautiful video.
This was really helpful! Thanks!
Thanks for the post!
Great explanation.
Great video Martin. You have a great presentation style =D
Thank you, excellent video.And thumbs up.
Very informative Martin..Thanks .
Thanks...yes...Hantek will happen in the future...it looks like they have some nice scopes.
Very instructive. Go on with it!
its really excellent teaching
Excellent!! Thanks a ton
Very Good Presentation and Informative. Thanks!
Keep up good job. Well understood! excellent!
Great video - thank you
My pleasure!
great video finally being to understand how to use my scope
Brilliant. Thank you for sharing. Now I can trigger :)
Really helpful! Thanks a lot.
Thank you, excellent video.
My pleasure, thanks for the post.
great video
well done!
Thanks Pete.
Excellent!
My pleasure.
great video!
The video is very helpful,and youtube is a good tool ; )
It is very helpful 👍
Thanks!
Much appreciated!
There is an importatnt setting in addition to the time base setting: the pre-post trigger amount! It's handy when you want to look events before or after the trigger event.
thank you professor!!!!
very helpful thank you very much !!
very helpful video THX
Thanks, it works
Brilliant.
A few comments:
When using a slow timebase, you could just turn on the power supply to see the slope and the run/stop button would probably freeze the curve.
When using the trigger, turn auto mode off, this way you will only see events that triggers the scope. Auto mode will automatic trigger, when no trigger condition is found to keep a line on the scope.
Thanks...Dave Jones of EEVBlog I think does a comparison..I've not yet had the Tektronix in my hands.
Hi Martin great video!just wanted to know how to check and set up to check flow or gpm from a hydraulic manifold valve.
Wah g maza as gya. But behtreen traeeqa Hy teaching ka
Great video thanks! Was wondering is there a way to monitor the signal as you are waiting for a trigger to happen?
The scope should show a signal still when in single shot mode until the trigger occurs. the reason why your particular scope takes forever to 'trigger' is not because it doesn't trigger right away, but because it triggers and then has to collect data for the rest of the screen/memory buffer to fill.
All 3 tutorials are great! Our company bought a B&K 2530B scope. I am trying to learn how to use this thing.
Could you please create a video, on how to test quadrature encoders. Maybe show some problems in the signals generated and how to troubleshoot them.
Also, how do you hook up a scope to troubleshoot for "Noise" in a electrical cabinet?
What do I look for? And how much,is too much?
thanks for the post
Have you done a video on network analyzers? I appreciate your videos/teaching style and haven't found a decent video regarding the tool on youtube.
Great work! How to use an Oscilloscope #4 please
nice tutorrial
The rise time is measured from 10% above base to 90% of top. A trigger should only ever stop your scope, not start auto mode. if you want to run from a stopped condition you should just hit the run button. the scope doesn't constantly trigger in auto mode, it only triggers when the trigger condition is met (raising edge over your 2.something volts in your case).
Thank you
Thanks a lot :)
hi martin, I really like your channel!!
I wonder if it would be possible for you to review some of the cheaper USB or portable oscilloscopes (like the Hantek ones)? As i'm looking to buy a 'scope and don't know what to look for in terms of specs and they get very pricey.
You should perhaps mention that the ground pin on most scopes is mains earth referenced. so if you measure some equipment that is also having it's internal ground mains earth referenced, you will have a problem if you connect your scope's ground clip to anything but the earth referenced ground level on your device. In extreme cases you may blow up your scope and/or whatever you're measuring and/or your hand.
Great video, Martin.if you can upload video " how to measure RF With antenna connected in the oscilloscope through the measurement will only antenna
Thank you so much. Suppose if I want to capture a jump from 10v to 15v what would be the settings. In my case the lower cursor always starts from zero
Hey Martin, this is great. I followed your video step-by-step and found that instead of a linear ramp-up to 12v like your power supply delivered, my power supply, a Thurlby Thandar PL330QMD, overshot 12v up to 13.2v before it rippled down to a steady 12v. I guess this is worrying if a circuit you are powering is voltage critical. I have a Rigol DS2072 oscilloscope for the analysis. Thanks again for the great tutorial,
Great videos. Thank you. Question. How did you learn? Self taught? School? What's the best way to learn. Just get this stuff then do it?
hi martin great video
im a radio ham here in the uk and getting in to the kit building side of the hobby so im getting some good pointers towards what test gear to buy
good work pete m0mnu
That was a huge help, many thanks (im using a UTD2051CEX) ...
I would be interested to see the comparison with the agilent scope.
0:18 where is the lost episode?
Joking. Excellent video.
I am using a floating oscilloscope and not getting that straight horizontal line when I turn a power supply on. Could it be because of the floating setup?
Tutorial: How to use an Oscilloscope #4 would be greatly appreciated
I saw a label printer called as LM160 of Dymo, which was placed on the top layer of the bench behind you.
As you mentioned a few lessons back, you can't just go and plug in your oscilloscope straightaway into the mains! And here, you are connecting into a stepped down power supply. So, what is the max volts that you can place into the scope? Is there any built in protection for such an accident? Say if you are probing around and you get across mains or plate (yes, I'm dateing myself here... ;-)) voltage of a valve? And what about the dreaded direct short to ground from power supply to scope...how to avoid? Even a "cheap" scope is "expensive" (so says my wife) ;-)
Thank you for this video BUT can you repeat it using a regular down to earth oscilloscope.?
really awesome video, but MAKE SURE YOU CHANGE THE "SWEEP" MODE TO EITHER "SINGLE" OR "NORMAL" so that your oscope can stop right when the signal happens.
This is awesome - definitely going to try it out! Unfortunately I have a really basic problem with the scope I'm using (Iso-Tech IDS-2204E) - I don't think it recognises my USB stick?! I thought I'd saved a bunch of stuff to it (definitely selected 'To File' as the destination) but none of it was on the stick when I checked afterwards. I can see the files listed in the scope's internal memory, so it looks like it just ignored my USB stick. There was definitely nothing else plugged in to any of the other ports at the time. Have you (or anyone else here?) had this happen before? I can ask around for another USB stick to try but everyone's gone home for the weekend now, I'm hoping maybe I'm missing something really obvious. Sorry to ask here - I can't find any kind of forum on the official product site. :-(
