Agreed. Maybe also the Maker Hawk oscope. Thanks

I'd love to review it if I can get my hands one one.

Theyve been making the best budget logic analyzers for years.

500us. What's "us"?? Junk.

kelvin•hertz-huh?

Yes, it runs independently of the scope.

Yes, the UI is done with the MCU not the FPGA.

LeCroy scopes can customize the colors. Of course..... they cost a ton!

I did share this finding with DreamSourceLab and they told me they are doing some analysis and I am hopeful this can be addressed in a future firmware update.

@@KerryWongBlog Today is Feb 28 2024. Any news regarding this issue? Thanks.

​@@gregandark8571I have not heard anything yet. I will ask and see if there is any update.

@@KerryWongBlog Thanks for your reply.

Less is better! I have an oscilloscope with 125 uV divisions, but only before 1.2V in this mode.

it looks like it's mirrored - the extra pads on the PCB surrounding the BNC jacks is also mirrored (presumably for some kind of active probe! That's pretty impressive to have on such a small scope)

Thanks! You do pay a premium for the form factor of the DS4T1012. TO1154D is considerably larger. OWON HDS series are also larger than this one in size. If you are flexible with the form factor, you have a lot of choices. I should be getting a Hantek TO series next month so I will let you know how well it works. But the TO series is much larger compared to the DreamSourceLab one.

The Rigol 802 base is the only cost comparable model at 299. It has 12 bit vertical resolution but is only 70 Mhz BW. So 5ns/div. No sig generator, Shared ADC. You might be able to hack it to 100Mhz and overclock too. Of course it's a 7" touch DPO display so it's really a different class instrument, for a different use case. It's powered via USB C though so it's very portable and can be battery powered. The Rigol has much better connectivity.. LAN and HDMI and USB. You can connect a large touch screen monitor and the screen scales up and touch and mouse works. It's really what suits the needs not just specs. You can't toss it into your tool bag like this 150Mhz

Yes, its the better osciloscopio cuality/price

@@khl6367 What tasks do you need more memory for?

My omission. I did retest and the results were similar.

@@KerryWongBlog So it seems like nonlinear filters are applied to correct the frequency response. They shift the phase. It's a sad situation.

Depends on the quality of the material used. Some rubberized things do not go "sticky" even after a very long time (like good brand DMMs). When it goes "sticky" it's the plasticizer coming out of the plastic actually!

What its the better osciloscopio quality / price for you? Cheap, médium and low - High

$250, or there is a 70MHz model for $150

@@jaro6985 That price is too close to the Rigol 800 at US 299. Unless you need something portable/dc powered.

Sure the Rigol DHO800 is more capable, but it's not a fair comparison as the form factors are totally different. Specs apart, the form factor is what makes this DS4T1012 stand out in my opinion. The oscilloscope market is very competitive these days for sure. The more competition the better. And competition is what drives innovation.

they could have made a Android version of DSView and make their DScope models work with it, it would have been the much more capable option in my opinion while still being a tiny handheld formfactor and even dual-use everyone got a phone with hardware thats much more capable than their stm32 frontend. and everything else gets handled by the fpga anyways

@@gamerpaddy IMO, the STM32 is quite appropriate! It doesn't have to do H.264 encode / decode etc, it just displays a waveform and reacts to touch / button inputs. (The HARD work is done by the FPGA!). The waveform update rate and input responsiveness already looks quite decent to me! Sure, they could have used an Allwinner / Rockchip etc CPU but it would only serve to increase the BOM cost! IMO, a far more VALUABLE feature would be to add Bluetooth and / or WiFi thereby allowing the 'finicky few' to establish a _wireless_ remote connection

@@KerryWongBlog If they could rev 2 it and add an HDMI out with touchscreen input like the DHO800, it might be the perfect enthusiast bench and portable combination. Seems like it has the cpu power, might need some extras for the HDMI+touch in/out like Rigol has. Really nice boot and update frame rate.

Mee to

What about printing a new case on a 3D printer?

Just wanted to set the record straight. I do not accept anything beyond the products themselves for my reviews and the terms under which I do these reviews are that I would publish my findings as is. If you have watched my other review videos you will see that I have no problem pointing out issues with the products sent in.. So no, I don't promote anything on my channel. I try to present all the facts and give my opinion on things. The clip you pointed out, I cut out some of my rambling and yes I do have my theories but at that point it was way beyond the claimed 150MHz bandwidth so it really doesn't matter.

@@KerryWongBlog +30% amplitude increasement from 50Mhz to 155Mhz you have 200mV at 14:40 and 260mV at 155Mhz and it looks to go even higher? how does that actually stack up.? with a +30% gain in amplitude.. shouldnt it be linear or decrease? I dotn recall I seen that before... why such a massive amplitude increasement? And I have watch your videos for a while, and lately you do come acroos more slimey than previous.(sadly) but maybe its cultural differences and how you role, and you wanna push things on your viewers and be loyal to who'ever daddy is gifting you stuff, not leats when you have a financiel incentive to piggyback ride on your subscr. purses.. It does not look good, when your start talking about trickery on weird behaving products, and then its cut out.. hence info that could put the product in less favorable light. if vendord are using trickery to push up on specs, to decieve, like we have seen again and again from CN.. shouldnt it be something like that, that would be interresting to analyze for your subscr. who I guess Mr Wong is your most important factor, and not some sugardaddy in China that wants you down on all four while getting acces to your subscr. purses..?

Can you provide a model that's portable, 2 channel, 150Mhz, and half the price?? There is the Zoyi ZT703S which is 2 ch 50Mhz and ~$80 - it just JUST came out - only a handful of people have them in their hands so far... still waiting for mine to arrive
