Thank you for your software. You will find here included The Hantek6022 Digital Back End drawing, from page 16 of your Manual. Tell me if you find some mistakes.
Regards.

I didn't look at EEVBLOG for a longer time, so I only discovered your picture today - merci !
I see three small necessary changes:
* The upper text in the upper square box of the AD9288 should read ENCA instead of EAYCA (my bad writing), it is ENCode channel A
* The lower text in the lower AD9288 square must read DB instead of DA, because it's Data channel B.
see also the ADC datasheet
* The text for the quartz below the CY7C68013 is 24MHz instead of 24MH7, also probably due to my quick writing.
Regard, Martin

Hi raxix13,
I changed the three text entries in the drawing, it is now included in the manual that is provided by the latest version 3.1.1
https://github.com/OpenHantek/OpenHantek6022/releases/tag/3.1.1
It provides a roll mode for slow sample rates up to 10s/div, mouse wheel zoom scrolling and a user config option to use the AC coupling HW modification:

Hello Martin
I just bought the scope partially based on your code. It seems my version is not compatiable with the hardware. SimpleScope and the Hantek one work, so I am thinking perhaps they changed CPUs and blocked your sofware.
FWIW I tried on Windows 10 64 bit and UBUNTU 16.04.
The other thought that occurs to me is the windows driver might be the issue. Which driver do you recommend for me. Windows would be my preference. That is my laptop.
softfoot:
I need to put a USB isolator between the system that I run OpenHantek on and the system under test as there is some cross interference, probably due to a ground loop.
The cheaper isolators only go up to 12Mb/s and the 6022 fails to work over these, and the majority of isolators capable of the required 480Mb/s are way out of my budget.
However I found https://hifimediy.com/product/hifime-high-speed-usb-isolator/ at a more reasonable price --- has anyone experience of these units ??
Thanks in advance
Dave
Gyro:
At that price it ought to be able to support 480Mbps as they claim. It's about the same price as a complete VDS1022I though. :(

Hello Dave,
Two other solutions come to my mind, either a potential-free laptop or this program on a smartphone:

P.S.: Isolation to fight a ground loop can work, BUT ...
