Hello Martin,

thank you very much for your helpful hints.

I had seen this video about earth/ground problems before I started oscilloscoping.
I thought I were safe because my Acer Netbook has no connection to earth.
It's switched PSU only has a two pin connector so I supposed it's USB interfaces earthfree too.
Also the measurement object, an audio amplifier, has no connection to earth.
I really don't know what happened.

Hi,

Some HW progress with Hantek6022: AC coupling - a nice 1 hour job. My SW supports this mod since v2.17-rc6.

Have fun,
Martin

EDIT: Fixed a small regression at the 10x probe setting, please upgrade to v2.17-rc8.

horo:

Version 3.0.0 is out (I've switched to a new version scheme):

- Better marker handling.
- Updated manual.
- Binaries for Linux, Raspi, Windows and MacOSX available.

Martin

Hi Horo, I didn't see the new mods or manual pdfs in win-x86 or x64 archives. I opened the source zip and copied it from docs. Hopefully you do not object to me posting them here for the benefit of others?
