Title: Rigol DS1074Z Teardown
Post by: echen1024 on January 23, 2014, 03:38:56 pm
I finally teardown my DS1074Z, without voiding the warranty! Sorry for the unclear pics of the boards, as I need to get my shit for teardowns figured out. I will also upload some high res photos if I have the time.

Thanks for the teardown, but LOL at how you opened it.

You could have used a credit card to pry it open, it wouldn't have left those dents in the plastic.

Edit: Altho, it wouldn't have been as funny as hammering the case off with the pliers and the screwdriver :P

Huh. That was a stupid mistake of me. I did not realize there were screws in the handle.

Good effort. I think for you a bit of preparation could go a long way. Your video feels like you were attempting this teardown off-the-cuff like how Dave does. Remember that Dave is an engineering veteran with many years of design experience through which he has built an intuition about how electronic systems function.

I suggest you consider doing a dry run with the camera off so that you know how exactly the case comes apart and what tools for disassembly. Before turning the camera on, you can also look for part numbers on the components and check the datasheets to help add some insight as to what is going on on the board.

I look forward to potential future teardowns from you once you figure out your camera setup.  :)

Ah yes. Preparation. I had decided not to do a dry run, unlike with my Agilent teardown or the DS1074Z review videos. Well, next time I do a teardown of my function gen, a dry run is in order.

Thanks.

Ah ha! Now that's good to know, so in total... 4 screws?

Also, if possible, mono is much better for this type of thing.

In the future I think You should prepare in advance with some proper tools to. Using a hand drill to loosen up some screws isn't the right way to do it. Why not use a ordinary screwdriver?

Sorry, but You lost me there...

Are teardowns the new fashion?
It's good when someone like Dave does one, offering great insight.
I don't think it is the way forward for a beginner to be doing them for the sake of it, especially without having learned the proper techniques first!
Take apart some junk and/or broken stuff!

If I could even afford such a scope that last thing I would consider is lets take it apart for sh!ts and giggles

Nice review and teardown.  But please invest in some screwdrivers.

I have practiced on a cable box. I will try it on the scope this time.

Sorry I didn't mean to be rude but you have to get some tools. That poor scope!

Get yourself a few junk items and pull them apart to get a feel for how stuff clips together.
As a very rough rule of thumb, lever plastic with plastic and metal with metal etc etc.

Good luck with your teardowns.

I was confident pulling the scope apart afther the Agilent using metal to pry it open. The main fault of me was not seeing the screws in the handle.

Oh god, I had to look away...

But then again, I probably left a few screwdriver marks on the first few things I opened, years ago. You live and learn.

However, if you want to repair others people's devices, and be appreciated for it afterward, please learn how to use credit cards, plastic pry's or round (not sharp) edged small screwdrivers to *carefully* look for and sense if and where any plastic clips are located. And look for screws hidden away, under lids and handles (as you now learned) but also under stickers and under rubber feet. Sometimes a screen or UI element has an aesthetic bezel that hides the screws.

But you get points for the attempt. If I ever need to open up mine, I now have at least one video to refer to first. That is in fact a new tool in the 'how-to-open'  arsenal of tools: YouTube. See if someone else found the hidden clips and screws already.

Can't remember the last time I enjoyed myself watching a teardown. You better have used a bigger hammer to open the damn thing.  :-DD
By the way, is the warranty sticker still okay? The case isn't, that's for sure.  :-/O

However, thank you, you made my day.

rather painful to watch...but A for afford hehe
the scope itself seems to be quite a nice piece of tec thou

Great effort I recently got this scope and wanted to see inside it but I didn't want to void my worrenty thnks for that

I recommend you get some nice big handled screwdrivers for some grip it makes it easier to un do tight screws . I feel sorry for you poor scope as long as you didn't break it its fine you should also have. An anti static mat and wrist strap for teardowns it will protect the ic's just keep it in mind next time.

This is a great teardown. Why? Because you learned a lot and you were brave and willing to share with us.  As they say "Good on ya!"  You absolutely have to make mistakes in life, you cannot become expert unless you make mistakes. Just try not to make any that last a lifetime or end a life.

Thanks again I am envious, that's a nice scope!  Keep us posted on how you like it and how you're using it. I don't have a scope yet so I'm very curious to know all about them.

Yes, Dave often refers to nice internal shots as pornographic. Well, then this was an S&M scene.

I was actually wearing one on my ankle. It's what I typically do, since the power strip and grounding point are under the desk.

That's actually not a bad idea. It would avoid swiping things of the desk.

Also, strictly speaking, it may be safer. the 1Meg resistor should already prevent it, but still if you grab hot with one hand, the path to the armband is through the heart to the other hand. On the ankle goes down.

I may follow your lead here.
