I am new to this sort of forum, I have only fiddle about over a few years, as I retired some years ago, just looking at this site it looks very complicated & above my head. I am only into very basic things with electronics but am interested in learning more. So hope I can get some answers very basic comments. I found out about this site from Workbook Wednesday on You tube. I recently bought a Hantek DS02D15 digital oscilloscope as I felt the price was cheap (its new, big boys toys) but not sure whether I have done the right thing, as struggling to work out how it all works. So I hope this forum can help me with it. I have found other sites on You tube that show you how to use different models of oscilloscopes, but not the Hantek DS02D15, yes I see they all do the same job, but to get some of hose things to work on my scope is a battle. I must say I would be lost with out my Multi Meter. So thank you in advance for what I may learn hear in the future.
