Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Your question interests me - I may be one of the few Experts here who has been trained on and has used an oscilloscope.
What aspect of operation do you need instruction on?
And, what sort of measurements or observations of what circuitry, do you need to do?
To measure a digital line, in other words?
Not an analog line?
Is your oscilloscope a one-lead (one input), or a two-lead (two-input) scope?
Better and better.
Set one channel as the sync channel (if that's the term your scope uses.) That's the one that provides the reference signal that all the other signals, as displayed, will be lined up with.
Set the probe for that channel to the sync signal source or reference signal source. The 'trigger' source, it might be termed.
Then you can set another probe, another channel, on the digital line, and hopefully you will get meaningful results and a meaningful display.
(But I confess: I have not been trained on automotive signal measurement or analysis. I'm used to 'bench' stuff, devices, audio or computer. So I may not have all the tips you need for this task. But I'm willing to help and advise further as needed, as much as I can.)
Does this answer your question, or do you need further advice ?
