    I really like how the touch controls work. Someone put a lot of thought in how to present the control elements to the user.

    I've been using the DS4T1012 for some time now. In fact I use it more than any other scope I have because it's so portable. I use it so much that I want it to be able to do more. Maybe they're being careful and want to release good code which makes the software development slower. Their code does seem above average in quality. I really would like the ability to import and export raw sample data because right now you can only do screenshots. Multiple triggers/memory segmentation would be awesome too. After that, more math functions! Custom protocol decoders, etc. :) I like the scope and this one seems to be using the same firmware. Some sort of screen protector would be good too because it tends to get bashed around due to its size. They seem like a good company, I hope they get recognition!

      No waveform save is a fail for me :(
      Internal storage is tiny, probably.

    Impressive. I have been very happy with my DeamSourceLab logic analyzer. I would not hesitate to purchase this unit at $100.

    Good to see your review of the DS4T252, I ordered one based on your review of the DS4T1012 and it has been great.

    Thank you for this video, I have been using the DS4T1012 for a while now and it never let me down, I find the quality of the scope and the software are excellent for the price.

    Another great video. I have a DS4T1012 based on your recommendation and have been quite happy. This 252 could be a great value for purposes where 50 MHz is adequate.

    Thank you Kerry. That’s a lot of oscilloscope in a tiny package for $100. I particularly like the protocol decode. This looks like this should be number one or number two on the list of scopes for people just starting an electronics hobby.
    Something of interest is the number of waveform acquisitions per second. A proper oscilloscope should have ring buffer capability in its DSP ASIC so that the buffer does not need to fill between acquisitions. The scope should be able to trigger from trailing data already in the buffer if trigger conditions are met. That makes it easier to spot on the screen a sporadic glitch which follows a periodic event which meets trigger criteria.
    I own an Owon HDS-2102S and a Zoyi Zotek ZT-703S. The HDS has 500M sample/s shared and the ZT has 280M sample/s shared. Those are two closest in capability scopes which I own. Owon rates the HDS 200 series at up to 10K waveforms/s. Zoyi does not publish that figure for the ZT models. I set both scopes to 1 mS/div to be a relatively fair comparison and look at the audio signal from an FM radio. Qualitatively it looks like the HDS might be updating the display at up to ten times the rate of ZT with the same signal, sensitivity and trigger conditions.
    I still feel that for the RF hobbyist, the Owon HDS-2202S is one of the best values, even if it isn’t least expensive. HDS-2202S has 1G sample/s on _both_ channels. The 200 MHz bandwidth lets radio amateurs examine RF signals directly up to the 2 meter VHF band. The downside is minimum 10 mV/div vertical sensitivity and maximum 25 MHz output from the function generator, though 5 MHz from the fixed set of arb. waveforms is decent.
    For a small signal audio frequency hobbyist, it looks tough to beat the scope shown in this video.
    If I were just getting started, I would put savings aside a little longer and go for a better scope instead of jumping in with a cheap model and then being stuck wanting something better.

    Thanks Kerry. Finally something sensitive so just ordered 100 of them.

    I bought the DSL pro logic analyzer and very impressed. So with Christmas on the horizon I'm tempted to treat myself to this scope 😊

    Thank you for another good review. I would have bought the DS4T1012 right away had it been designed in a way I could replace the battery without a destroying the the unit. I'll probably order this one. It will be handy for working on switching power supplies. If only the battery was replaceable, I think the DS4T1012 is off offered at a very fair price considering how powerful it is.

    Very nice. I need the protocol decode for my microcontroller projects, and my bench scopes are older and don't have it. But I have old eyes and hands and I'd want a control and display interface to use it most often from a tablet or PC. This 'scope seems quite stable, a 'real' o'scope, and has everything I'd need at a great price-point, but it's just too small for me to see and use well. The tiny touch-screen is made for younger hobbyists, so I'll have to wait for something comparable with a good USB PC interface.

    I wonder how to decode the SPI protocol with only two channels.
    Nice video, thanks.

    An interesting scope for light portable field work for sure. I wonder how much run time you get on a single battery charge? Is it as bad as the owon HDS2102S scopes?

  • @totalab.eletronica
    @totalab.eletronica หลายเดือนก่อน

    Excellent vídeo! About the scope, I really miss a sample rate info on screen and a frequency counter by hardware. Could you ask them to implrment that in Future FWs :) ?

  • @svofski

    This is my main scope. I love it, although the screen could be larger. The trigger options are lacking and setting the level can be very fiddly as it often misinterprets touches near trigger position as timebase change.
    I also miss TV sync options and trigger pulse width options.

    • @jheissjr
      @jheissjr หลายเดือนก่อน

      What do you work on that needs the TV sync?

    • @dannotto78
      @dannotto78 หลายเดือนก่อน

      He is repairing old analogue stuff (VHS and CRT TV). I also need TV sync feature. I have seen this feature on ten years old Owon handheld scope but is quite expensive for the specs that has. There are currently portable oscilloscope with TV sync feature but are very expensive, close to 1000 USD.

    Do you think it's possible to remove the rubber cover to change the battery?

      Not easily. You can watch my DS4T1012 review video, I did a teardown towards the end.

    The UI seems good, as demonstrated; but, a lack of connectivity to a bigger screen, for display purposes, is a deal breaker for me. There needs to be connectivity.

    I think this is not "Pushi Oscilloscope", maybe Pushy, probably "Touchy Oscilloscope" - (DSTouch DS4T252)
