Oscilloscope training resources
Oscilloscope manufacturers often have "generic" basic tutorials - before they then discuss model-specific features, which wouldn't apply to your specific 'scope (if the tutorials are from a different manufacturer, of course).  Learning about oscilloscope probes and their effects on signals, is also important IMHO.

This page has links for Tektronix learning resources about oscilloscopes and probes, for example, much of which are applicable across all manufacturers:

I would expect other big 'scope manufacturers to have similar resources.



FYI on the link above, Tektronix do (attempt to) collect the person's name, email address, company and country, before the tutorial(s) can be downloaded.
