A lot of great stuff!
The Frequency Response Analysis (FRA) is a great tool for my ham radio needs.
@ebclr and HKJ: Ground loop / USB-Isolator / floating scope hints are great. I still have two differential probes for stuff like this. But yes, this is something I should keep in mind.
@Andreas:Such an "angle cursor" for direct measurement is a really a new cool way to do somethink like this. Wow!
@MrW0lf: Great stuff in you picoscope threads! I need to reproduce some of your examples to get to the bottom of it. Excellent!
It looks like my new PC-scope offers some versatile and advanced possibilities I would have easily missed.
Thank you!
