.. my collection ..
Welcome to the forum. Are those PCB photos your mods? (very extensive shielding! )
Thanks!
RichardK did the shielding.
https://www.eevblog.com/forum/testgear/hantek-6022be-20mhz-usb-dso/msg344749/#msg344749I 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.
