I spent my time in jail working on getting these videos and checking sources for information on inverter (not just the Eg4) light flicker. Even the high end units have been thru this problem. It was productive use of my time.
I saw some of the sine waves posted here in the forum by users that probably have limited scope experience. I use my DSO's in the shop daily on DC circuits and I'm quite well versed in aliasing, bandwidth and sample rate. The scope I used was a cheap scope but one you see members had purchased, I purchased it for the high voltage probe which I did not have one. The scope is capable using only one channel and a time sweep that doesn't alias and drop data points.
I'm a tech, not an engineer but I certainly see some issues. If you want to start a thread and link some videos, I don't have a problem with it. It could use some discussion.
