horo:
Nice solution, well documented!

There was a long time discussion on github, where users proposed important probe attenuation values that should also go into the drop-down list:
https://github.com/OpenHantek/OpenHantek6022/issues/33
https://github.com/OpenHantek/OpenHantek6022/issues/37
Finally it was solved by the current solution. Either scroll - or just click into the number and type in your personal probe attenuation between 1..1000, e.g. 103 in your case.
Please look at github: https://github.com/OpenHantek/OpenHantek6022/issues/107

Gotcha, thanks Martin

My little project was a way of saying thanks! see... people are using your program!

Mind you, all I had to buy was the wee box, everything else came out of the junk box. It would cost more if one had to buy BNC fittings.

I had read all of this blog but had not followed the github thread,

Welcome to the forum. Are those PCB photos your mods? (very extensive shielding!  :-+)

Thanks!
RichardK did the shielding.

I tried to collect all useful software, info, manuals, datasheet etc. about Hantek6022BE.

I intend to make some more mods besides the ones mentioned in the forum (RichardK shielding and additional PSU capacitors).
My intentions are:
1. Separate power supply (5V - done).
2. USB insulation.
3. Separate power supply to the audio part of AD9288 and CY7C68013A, and if possible separate ground plane for these two chips and the input stage (AD8065).

I try to remove nasty hi freq. spikes (noise), but I think that we have bad ground plane.

This piece of hardware is designed very badly, very badly.
No one thought when they designed the hardware.
