EEVblog #675 - How To Reverse Engineer A Rigol DS1054Z

Dave shows you how to reverse engineer a PCB to get the schematic. In this case the new Rigol DS1054Z oscilloscope.
How does the discrete transistor analog front end and the software bandwidth limiting work?
How do you decode SMD transistor codes?
How does it compare to the old Rigol DS1052E?
Dave also discusses the low voltage ohms function of a mulitmeter, how it's useful, and how to test your multimeter to see if it will have any issues with in-circuit testing.

This Dave Jones character is pretty amazing.  It would take me 4 lifetimes to come close to the depth of knowledge he has.

Quick solution to looking at inner layers - take a trip to a vet or dentist & get it x-rayed.

Dohn Joe's comment is very disturbing. Have you even watched the WHOLE video? I did. Dave is just interested in how these circuits work. I highly doubt he is trying to copy their design. Don't just assume he has bad intentions. I highly appreciate the work he has done to get all these videos and knowledge out onto the internet where anybody can access them. It's a big help for others, like me, who are interested in a future EE career.

Fantastic work. I would love to see more of these reverse engineering teardowns. It really shows how the design comes together and how the manufacturer thought out the production. Best video so far.

I see you've finally upgraded to the latest version of DaveCAD! Exciting times :D

If you have a photo editing software that supports layers, then you can put the two images on different layers of the same document. Set the upper to 50% transparency and align/adjust. Crop the document so that everything is contained in the same rectangle.
Then, for printing, set the upper layer to 0% transparency and print, then to 100% and print.

Excellent episode, EEVblog (Dave). I've seen every episode up to this point and I must say I prefer episodes like this. I enjoy soaking up your decades of experience. I realize it's a lot of work to put together an episode with this much content, but well worth the effort in my opinion.

If you have a larger board and a via disappears, you can also use a stainless steel pan scrubber as a "really big probe" to narrow down the area in which it surfaces again.

Wow, thank you soo much for your hard work here. It is really interesting and your approach is very pedagogical. Thanks for sharing so much of your knowledge. The quality of your videos is great. I'm really a big fan.

[TurboAdam]

So THIS is what Dave's been up to for the past few days.  I was starting to worry!!

[groovejet]

2nd time ive watched, theres no videos like this available anywhere! Depth of info and effort...Top marks

[victornpb]

I don't usually rate videos, but this definitively have my like. Please, more like this.

"Always have a rubber on your pencil." Made me laugh :P

[timrotunda]

Great video, as usual, but I was hoping we would be looking at the finished DaveScope towards the end.

[rowlandcrew]

I like the intellectual logic. EE and proud of it.

[djscottdog]

I was going to say ab xray might help with the traces but you said it at the end . Great video

[andreblue_]

Cool. Now I have a urge to try this with an old rc car board I have just to learn it by practice.

[Washburn-rreh]

Excellent video! Your knowledge is truly amazing!

[untitled]

hey dude, seen almost all of your videos now.. Just thought i'd say i'm a huge fan. Thanks for all the knowledge and all that jazz :)

Another brill vid DJ!

Don't shoot PCBs up close, use zoom from far away to eliminate paralax(?) error (getting only 4 leads of a DIP-8 pack).

More rev-eng vids!
