Hantek 6022BE 20MHz USB DSO
jhotteoye:
I recently did a teardown wanted to do a review of the Hantek 6022BE myself but saw that Aurora has already posted a lot of good pictures and description of the instrument's guts - better quality than the cell phone pictures I took. What I can add is a review about the unit's functionality and usability (or lack thereof, as you will see below).

For anyone else that wants to make up the copper screening cans, here are the dimensions.
I made them up from some 0.4mm copper sheet from amazon.
The additional EMI shielding uses some Wurth Elektronik 30410S I had leftover from an audio project; effective stuff, but expensive.
Additional images show Richard's bypass cap mod's installed, BoM is included in my post on page 47.
Noise level is currently circa 8mVPP.
Just the AC mod to do.
How is AC/DC selected once the mod is implemented/

What are the criteria for choosing the right photo-MOS? Why was Panasonic AQY210EH chosen, and can it be replaced by Cosmo KAQV214S https://pdf1.alldatasheet.com/datasheet-pdf/view/89049/COSMO/KAQV214S.html ? As far as I can see from the datasheets, there is only one significant difference (besides a lower insulation resistance on the Cosmo), and that is I/O capacitance - Panasonic has 0.8pF typical and 1.5pF max, whereas Cosmo has 6pF typical (both at 1MHz). I'm not quite sure what the implications of this are. For example, will it badly affect the performance / signal quality; will it make the scope more susceptible to damage due to high voltage spikes, etc.? Does anyone have experience with using another photoMOS than the AQY210EH?
Edit: To clarify -- the reason why I want to use KAQV214S instead of AQY210EH is that my local supplier only has the latter in an SMD package, whereas the former also in a THT package.
