Pico scopes and such

[walterk]

I have recently started to delve deeper into problem solving with a Pico scope. in automotive applications, they already have a wide use and many libraries with waveforms, applications, etc.
I am wandering if any of you guys use scopes on Cummins engines? Where can one find "known good" waveforms? And, what waveforms do you find most helpful? I understand that Calterm is a very powerful meta data analysis tool, but surly there is room for a scope waveform analysis when solving issues form many different angles.
