Just so people can see it before downloading and printing, here are a couple of snapshots of what it looks like. And please be kind, I know I am not the best designer by far...... I do what I can.

And can anyone help with being able to read the internal temps via SSH in the command line? I am sure we can get some more accurate temp inside this way. My Siglent bench unit can only handle 1 temp probe and I have also used an infrared for external temp reading, but it would be good to see the temps at the core of the CPU at least. But again, after 1 hour of continuous sampling (two channel @4GSa/s) it shows stable at 43c approx. in a 25c degree room, so it is a very effective solution. Huge improvement no doubt.

Anyone?

I did a IC Identification for the back side of the Main PCB of this device:

Thanks CChin254, I guess I like your style a bit better then what I did here: https://gitlab.com/riglol/rigolee/-/wikis/MSO5000-teardown

Though as I want to keep it as one picture, I'll have to see how that can be done; but some new items here is good!

Btw, the reason my picture looks so 'weird' is that it's very high-res close ups and double sides overlayed. But for the chip identification, using a clear single sided picture probably works better :)

Also, I'm in agreement with
Hi CChin254 I do not understand why they use Spartan 6 for communication between Kintex and Zynq the both Kintex and Zynq have a Gigabit Transceivers the more efficiently would be use GTX for sending data between Zynq and Kintex...
Probably Spartan 6 placed for other purposes...
I don't think the Spartan sits there exactly like that, as we can very clearly see the high speed communication lines between the Zynq and the Kintex7 (especially on X-ray). So are you certain that the Spartan6 is not some sort of 'controller'. IIRC the spartan6 only has a (slow) SPI link ... It's been too long since looking at the architecture, and sure want to pick it up again :)

Yeah I need to figure this thing out, I'm just too busy now of days since school started (last year of High School). Hopefully I can figure this out and fix the block diagram soon enough. Thanks for letting me know anyways!

Any progress on line thickness in XY mode?
Thick marker line is terrible :(
