Back in the day used "tune scopes" a lot for engine analysis as a mechanic,. And yes that is a very old CRT scope, it does the basics and while I would like to have a fancy new digital one I do not use it enough to justify the cost of one.
@@AuMechanic I'm pretty old and remember seeing the early Sun diagnostic machines. First one I saw was in the very early 80s. I didn't have a clue what I was seeing on the screen. I knew what oscilloscopes were, just not in that context. Always dreamed of having one growing up in the 70s and playing with electronics and CB radio. In the very early 80s, a shop owner in a TV shop gave me one when my new wife and I were buying our first TV from him. Since then I've "upgraded" a couple of times. My newest scope is a Rigol DS1102C I bought about 12 or 13 years ago, at least. I hope you get the chance to get a digital scope at some point. They are very useful, but an analog scope is also still quite useful on cars. If you're still working on cars, perhaps you could justify a DSO by the efficiency of being able to analyze fuel injectors, ignition primary and secondary systems, fuel pump current tests and relative compression tests. You might find that you would use a digital scope much more than you currently think. Thank you again for the video and for the response. I look forward to more videos from you, you are good at getting information across.
whats the voltage and current from a magneto pickup? there must be a way to simulate this to make an ignition tester, PWM maybe but it's probably above 5 V
If the oscilloscope has an "invert" feature, the image will be correct flipped vertically. I work with oscilloscopes measuring secondary and many other signals captured with the tool. 20:1 attenuation correct? Thanks for taking the time, and great work. Friends that work with small engines also thank you.
Hi The scope I used back then was a very old CRT scope so no invert or other features. Also the signal is taken from the primary side of the coil however due to mutual inductance of ignition coils you can still see the secondary winding behavior through the primary with some variation to the pattern, as opposed to taking it directly from the secondary where you can measure actual voltages.
Thanks for doing this. There are virtually no youtube videos on using a scope to look at small engines. That's quite the vintage scope there. ;)

Did you ever get a newer scope? There's so many small ones now.

Thanks for the video, and sorry about the crazy politicians.
