Alex Muir explains what an oscilloscope is, how it works and how to perform two tests: a relative compression test by measuring current into the starter motor, and a full pressure test using PicoScope's WPS pressure transducer.
I took a course in college over electronics and how to properly utilize an oscilloscope, and I believe I learned even more here in the span of about 20 minutes than I did in a whole damn course. Bravo.
So far, the videos produced on this channel have really astonished me, and, as an avid car lover with a decent depth of automotive knowledge, it has already answered questions that no other place has been able to answer for me. And the live presentation of the information is so incredible smooth that it is breath taking. Good job, and, please, keep up the good work!
Thanks this is a good video. I liked it, and for a mechanic I'm impressed you are actually troubleshooting! not part swapping! You blew me away! I was totally surprised when you clearly and actually described how the oscilloscope works. This is a great video. Thank-you. Well done.
Amazingly easy to follow introduction to automotive use of a scope. And not boring either, watching the whole video was fun! Best explanation on the use of the amp clamp ever!
I never knew how I could apply an oscilloscope to the automotive industry. That was one impressive video. It not only explained how the scope functions but what else it can be used for. Thanks for posting such a great video. Barry
You’ve done an excellent job explaining how a scope works and how to use it, I haven’t found this on any other channel most times they just use it with very little explanation thank you for this series. You have a new fan!
Maybe you can also learn how to save and check the oscilloscope waveform with the comprehensive diagnostic equipment: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xgJQ8nncl1g.html
Such a well done, and EXTREMELY informative video! been trying to find a video that lays it out like this for a minute now! Thank you very much!!! Keep it up!
Thinking of get an oscilloscope. For my DIY interest on cars. With the way you demonstrate the use of one. I really will look into it. Thanks for your time on doing a great understanding video. 👍
I purchased this course, and the alternator video (the one after oscilloscopes) is WOW 😲💣🤯!!! Best explanations ever... 👍👍👍 My recommendation to everyone for this course... I learned in this course so many things about how cars work, that I couldn't in few months researching on the internet...
Nicely done this video. Thanks for putting it together and sharing it. I am in the process to buy one but didn't know how to use it. Now, this is a start for a DIY on my vehicles.
Alex this is a fantastic class for the use of Oscilloscope and also the use of the Pico. I was looking for a class which was it helpful and detailed on oscilloscope. Hopefully you can make more videos like this on the use of the Oscilloscope Pico on different uses like how to check maf sensor or map and others will be awesome.
Excellent stuff, especially the comment about knowing what to look for and how it works. Many times I have tortured a student by not giving the answer and asking more questions perhaps the smallest of clues because I know they know the answer and to watch that moment when the light goes on in their brain and they fix the problem on their own. Their confidence is then doubled in their own abilities.
I don't use oscilloscopes for automotive applications, but this video finally helped me understand what triggering does. No one else has dumbed it down like you have.
Greetings, Mr. Alex Muir, I am Divyansh Sharma, and I love your video course. I’m a man who wants to learn about cars and spend my life with them, and this video course is really, for me at least, the bridge to a life of automotive excitement. I love how you go into extreme detail about everything, and explain it with all your heart. It’s really helpful for car enthusiasts like me, who want to go into cars, but know a fraction of what there is to know before you can pop the hood and get to work. I especially love those little bits of humour you include in the middle, they really brightens things up. I admire how you really know what you’re doing, which gives me, and I’m pretty sure everyone else, confidence, that we won’t screw things up when we try to do something as little as change the oil. Since I love your course so much, I ask (in the best way possible): When can I get to see the rest of it? You explaining gearboxes, differentials, and with your amazing 3d graphics, the braking system, the power steering, and suspension. I really admire what you’re doing, which is why I’m so excited to see the rest of your magic. Thank you so much for taking time to read this, and I hope you’ll get back to me soon. Regards, Divyansh Sharma
Man I love this course . It's very detailed , well explained , it has great quality. It's really worth it I would say the best 18 € I have ever spent. Looking forward for the upcoming videos ! There is something I would like to ask though, I am unable to find the 3D animations on the website , I don't know about the app because I haven't installed it yet but I would love to have that feature on the website so that I can access it from my laptop. Wish you all the best and keep doing your great job!
thanks- some basic settings i always got confused is now clear in my mind,thanks Alex. good job ,now i can start using my pico on cars to check signals,injectors -commonrail where high current is drawn, cam sensor,crank sensor,timing ,wow a whole world opens.on todays car forget the meter, check canbus speed,signal well inside the ecu whats happenning . Respect
I luv how you analyze the function and the conversion of the scale patterns /voltage you did it in a way that just got through to me set me up on some more research thanks much
You my friend are an excellent teacher. I have been looking for such a long time on the Internet to find someone who can teach me how to use an oscilloscope. You made it seem so easy. Answered so many questions that I could never find on RU-vid . This is why I've subscribed to our channel. Thank you so much for all the details you presented in this video. 👍 👌
Maybe you can also learn how to save and check the oscilloscope waveform with the comprehensive diagnostic equipment: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xgJQ8nncl1g.html
wow nice example showing how a multimeter(voltmeter) really works and how and oscilliscope is different. Ive watched so many videos on oscilliscopes and never was that point really made. Ive heard other electonics channels mention something about votlmetes being an average, but this example makes that really clrear, thank you.
Just the information I was looking for! I'm looking into getting a scope but I was curious what the real difference is between this type and the automotive type that has the scanner included. Very helpful video, and came across it by chance.....thank you!!
Excellent video i have hantec coscilloscope connected to PC never really understood how to use it properly your video has made it much easier to understand.Thanks

Hey Alex, great stuff going on here. Keep up! Would be really keen on something about mild hybrid systems and how an Integrated Starter Generator (ISG) system works. Maybe Suzuki or Bosch could lend you one of their engines/mild hybrid systems. Many new cars are coming up with those systems and the open market technicians are absolutely unaware of the builds. TIA
dunno who is this guy..but apparently he has a state of the art knowledge and plus state of the art ability to explain/ I wonder why this video hasn`t gather millions of views like some others :/
That final pressure peak that appeared to be lower than the rest was not accompanied by current draw. So it was the engine's inertia facilitating the compression stroke. You can also see it is a somewhat wider/slower peak.
I toughly enjoyed this video, having a degree in Automotive Service Technology, we went over basic oscilloscope operation but never delved into anything except electrical theory and a quick check for spark plug wires. Thanks
I commenced using O-Scopes back in the linear days. Since the inception of the digital age and the availability of sensor units, the O-scope is much more valuable across the board. With the correct supporting programs almost anything can be scoped for diagnostic purposes.
The future of automotive diagnosis. Very informative video. I can see how a younger tech savvy mechanic would easily adapt to this but I can also see how the old school guys will dismiss this. Either way very helpful video.
That was very interesting to watch, specially the correspondance between the various input signals to give a more complete view about what happens! I as not actually looking for a video about how car works, I was just looking for information about what was specifically different between Automotive Oscilloscopes and other models. I'm still not 100% certain about the differences, but I guess it's about: - Specific probe management to do conversions of current into human readable units - Higher range of input voltage not quite sure if there's anything else? Basically what I'm wondering is if a bench oscilloscope can be used on a car, and if an automotive oscilloscope can be used to do electronic, computer and audio-video repair/diagnostics. And yes, great video :)
im ok12 I love a good puzzle problem. I bought a autel mk908 and their 4 channel oscilloscope. About 2500 total but it will more than pay for itself with time
Thanks for this. I think it would be great to take it a bit more advanced. I'm very keen to understand the parameters needed for a good automotive scope, and why. For example, what is bandwidth and what is optimal for automotive, and why; further, what sampe rate capability is best, particularly to achieve a good sample rate at a timescale that works well for automotive use --- ie in the ms no micro or nano second scale. what buffering capability is needed. Explaining these parameters, and what to look for in an automotive scope in a simple accessible way would be magic.
I'm so thankful that as a young novice technician I had a certain instructor when I was working at a subaru dealership and he was a kinda rough around the edges older guy and alot of the techs complained about him and said he was old school and you can't make any money doing things the way he would teach ect but he made sure that we could use and understand the 4 channel scope that was built in to the factory scan tool of that time and I thought it was kinda cool anyway so I really drove into learning how to properly use it and just anything I could do with it and fast forward 10 or 12 years I'm working at a European and exotic car dealership and I found that I was able to make very good money mainly working on electrical problems and electrical diagnostics that most of the guys ran from ... I'd much rather make the same money as the guy next to me and not be filthy at the end of the day lol but seriously if it wasn't for joe the Subaru instructor I wouldn't have been able to find my niche in the dealership and make the money I was able to
