Please turn off "Stable Volume" in the video playback setting (the first menu item after clicking the gear icon) as for some reason, this new TH-cam playback feature made the video much noisier than usual.
The SoM is the CPU. It's labelled RK3568, which is a big RockChip ARM. The device under the heatsink on the mainboard is almost certainly the FPGA. Basically, the entire main-board is oscilloscope specific. I'd bet the SoM is common with some of their other devices. all they had to do here was hang their oscilloscope hardware off some of the spare IO. It's *probably* a custom Micsig part, considering it seems to be labeled "MS_RK3568_CORE_V1.0". I'd guess "MS" stands for MicSig. The device near the FPGA you point out as flash is I believe DRAM. The part number doesn't yeild any search results, but it appears to be the same as the DRAM on the SoM. The other large part near the FPGA is "NTSRAM", which seems to be a funky flow-through SRAM variant (seriously, look up S7N801831M. It's a interesting part). In any case, it's SRAM.
Right this threw me off too, it's in a standard SBC form factor (rpi has a pi in this form factor or similar iirc). The card is labeled as what it is and is likely not the oscilloscope side of things.
The label on the SoM points to the RockChip RK3568, an Android compatibel ARM SoC. So that is the Application processor. It makers sense as the oscilloscope part can stay the same for many years. However, as Android advances, so does the requirements for the application processor. So by putting that part on a separate board, they can keep the same design and upgrade the application processor in the future without a redesign of the oscilloscopes main board.
Thanks for the video - really useful to see the inside of the scope before deciding whether to buy! Looks well built, the question is how long is it likely to keep running?
I will be using this scope as my main scope and you will see me using it in future videos. So I will definitely keep everyone posted on the long term reliability.
Any idea how to recover the unit from a failed firmware update? I just got an STO1004 and did a firmware update over Wifi, rebooted and now all I get is a Micsig splash screen and constant reboots. Pretty poor design to brick a unit on a failed firmware update. Should have a fail-over to a golden image so the unit can easially be recovered....sigh.

Nice construction!
As others have mentioned in the thread below I got it reversed, the SoC module actually contains the OS the FPGA is on the main board. 🙂

@@KerryWongBlog I checked today with a reseller in the UK and they offer a 3 year warranty on these Micsig units - all looking really good.

Brother Please Review Hantek 6022BE....
Yes!!!
Don't turn it on!
Well you know what's next. Thank you!
