I've got to stop looking at all these reviews for cute little multi-scopes. I have a bench HP, a handheld Fluke, a smaller than the Fluke but good $190 handheld multi-scope in my tool bag, and a couple of $15 to $30 'toy' scopes. But the Chinese keep coming out with interesting handhelds every month with more bandwidth, better triggers, ever more features that work better, and at a lower price. I'm almost glad this one has problems. I could turn into a scope junkie if I'm not careful. :) I would so love send some of this tiny gear back in time to my 13 yo self. A handheld multi-scope, a TinySA, and a NanoVNA would make a heck of a start for just about anyone back in the 1960's.

It may have a few problems, but from what I can see they are not any worse than other devices in this class. Comes with the territory.

[@sa8die]

i like how you went over everything with this one part,.

[@uni-byte]

Thanks!

[@jerril42]

Thanks, it looks interesting. I'm still not sure If I want to go with a portable cheap scope or wait until I have the funds for something more substantial. Something is better than nothing, but I'm in no real hurry. Loads of other things to keep me busy. I hope Reggie is recovering well. Take care.

[@uni-byte]

Agreed. Reggie, unfortunately, tore out some of his sutures. Still need to see what can be done about that, but otherwise is recovering well. Thanks for your thoughts.

[@andymouse]

The idea that you can't extract the images in this day and age is almost a deal breaker even if you say' its 70quid ' I find that bizarre but great review. I think I will stick with it's little brother which I'm quite happy with as my portable.....cheers.

[@uni-byte]

Yeah, I think that is a real miss on their part. Even if it added $5 or $10 to the price a way to get the files off would have been a real improvement.

[@electrifire1059]

Wich one is better between zeeweii dso3d12 and dso2512g

[@uni-byte]

Understandable question. The DSO3D12 has a larger screen and a pretty good DMM, the DSO2512 has a nice rubber cover and video out. Other than that they are pretty well the same.

[@electrifire1059]

@@uni-byte thank you sir. Now im going to place oder for dso3d12

[@yeroca]

Is the firmware upgradable?

[@uni-byte]

Yes it is. Mine came with the latest firmware already installed.

[@jean3xyz]

Hello; could you tell me how to delete an image view?

[@eggmangoogle3146]

It's in the video, you press the button to the right of the on-screen garbage can.

[@uni-byte]

Press Shift -> Save to view the images. Select the image to be deleted with the cursor buttons. Press the x1x10 button to delete the image.

[@uni-byte]

Correct.

[@mikebond6328]

I think I would buy it if it had all the bugs worked out but as is I’m not really crazy about it.

[@uni-byte]

I'll try to mention some of this stuff to Zeeweii. It remains to be seen if they respond.

[@HenrikHvalpen]

​@@uni-byteAny updates?

[@uni-byte]

@@HenrikHvalpen Their reply was (paraphrased) "We don't have bug reporting process". I still use mine nearly daily. The little issues don't really bother me as I'm used to them.

[@HenrikHvalpen]

@@uni-byte Thanks for the reply. I was originally looking into buying the ZT703s but it seems to have a lot of bugs. Then I looked for a DPOX180H because it seems to have some good reviews, but also a bit more expensive and it only works as an Oscilloscope. Then I saw the one you tested and it's quite intriguing. I have also looked at a HDS2102s which also is a 2-1 one solution, but it's pretty expensive too. It's my first time buying an Oscilloscope and I really want to make the right choice the first time.

[@uni-byte]

@@HenrikHvalpen I Understand. When I was buying my first scope I only had one option in my price range .. a Heath Kit single trace 5MHz analog scope (and I had to build it myself!). These days there is too much to choose from and that in itself can cause issues. Good luck!
