There are many places to get known-good waveforms:

A free resource that I use, quite often, is a Facebook Group .
Another is the Picoscope Library, but you must have a picoscope attached to your PC to use it.
Keith Perkins has a very good library, at l1training.com . You must register for a free account to access it. 
.
As time goes on, I am seeing them, more and more, in Manufacturer Service Information.

A quick google search can, often, bring good results, too.

An expert is someone who knows each time more on each time less, until he finally knows absolutely everything about absolutely nothing.
