You could always hook up to the FPGA JTAG connector and do a device scan to see what FPGA it is

I would like to see a teardown of a peice of test gear while sat next to one of the designers. It would be interesting to get clarification on some of the things dave cant answer.

There appears to be a short between pin 6 and 7 on U32, it's on about time 10:15. Some of the solder work seems to be How Do You Do, thumbs left right on this one Dave.

Another osciloscope teardown. Cool. Now I can apply to service osciloscopes. "What are your qualifications for the role?" "Well, I've seen all 800 EEVblog videos, some of them repeatedly." ;-)

Your sure thats a clock and not a bomb?

[benadams]

Thanks for the quick tour of the inside.

It looks good, maybe time for one more scope.

8:37 The Blackfin are used for two reasons, low cost and the abundance of skills in china for that platform (They trade IP between companies as well), the BlackFin (in today's standards) is the cheapest high efficiency fixed point 32bit DSP. I own a BF533 board and SHARC really amazing stuff. Your`e right assuming its the processor used for the Display UI and Management.

The processor architecture was a collaboration between INTEL and Analogue Devices.

They also have a 100MHz version @ $500, would be interesting to see what the actual bandwidth difference is between the two. I doubt there is any difference in the frontend design.

You get a Thumbs Up for the Proper Reference to Muntz! With a photo yet! Dave, you surprised me with that one; I cannot believe you knew of him!

[Grim_im]

I often find myself craving a cough to clear my throat when I hear you speak in the lower tones. Maybe it's just me. But otherwise you are a saint for this channel. 10/10. Would subscribe again. Would recommend at parties.

A Haiku

Silly engineer
Why do you disassemble
that oscilloscope

[blueslayer]

I'm pretty sure that state diagram at 13:20 can be used for human transmutation.

[dorota]

Thanks for the schematics when discuss parts eg. Micron RAM. Always too lazy to check datasheets myself...

[vandalest]

@15:28 and @18:56, there is a bunch of NEC UD2-4-5NU relays

[DoItYourselfMusician]

Should've written your name inside. I kinda like this scope, might have to get one. I mostly do audio so it's plenty good for that.

Looks like not all caps on the secondary side are Rubycons.
the 35V ones are definetely NOT rubys, but I can't see what else they could be.
Seems that some of them are also Lelon...

PS: nothing wrong with saving a penny on the primary cap. They are most likely the last things to fail. Well at least when your electrical grid is decent and they don't get many surges...

6:24 I guess it is not the completely finished and polished version.

[FrankenPC]

I love how you peeled off the tamper sticker on a video Siglent will see. Classic Dave :D

[jaa]

factory testing / calibration maybe? J16

Threadlocker practically guarantees metal inserts because it uses a metal-ion reaction, binding two metals together
