Good morning and thank you for posting and welcome to the forum. As an electronics engineer your knowledge will be invaluable and we look forward to any input you may have on an array of automotive issues we all have to deal with on a day to day basis.
A good place to start would be to download and install the PicoScope software on your PC and use in "demo mode". This will give you full and complete functionality and allow you to view the "Automotive" help files stored under the AUTOMOTIVE tab. To down load the software please visit, https://www.picoauto.com/download-software.html
, where you will also find the minimum PC requirements.
Here you will find complete instructions and how to use the scope and apply numerous measuring techniques to all forms of sensors and actuators. The software does not time out and is continually updated free of charge with new features and help files.
The software is not manufacturer specific as we are measuring signals from components and not communicating with the vehicles on-board diagnostic system.
The PicoScope is an incredibly reliable USB based oscilloscope which is sold the world over and forms part of many vehicle manufacturers’ diagnostic tool kits, accompanying their own dedicated scan tools.
What you get with the PicoScope is a true oscilloscope with no interruptions or modifications to the signals you are measuring, so revealing the signals produced by the vehicle whilst preserving the integrity of the signals for display on your screen
With the signal captured on screen you can then choose to filter accordingly, safe in the knowledge what you have captured is “fact” and not an interpretation of the signal as many combined scan tool/oscilloscopes will have you believe.
For information about the kits we produce and the leads contained in these kits please visit, https://www.picoauto.com/diagnostic-kits.html
Starting out in diagnostics you will also require a dedicated Scan Tool for the vehicles you intend to work with. This can be in the form of a dedicated manufacturer tool or a generic tool. The choice is endless and it may be worth you asking the guys here on the forum what they use and more importantly what they don’t!
I hope this helps and please feedback if you need any further information.
