How to promote an USB oscilloscope to individual engineers? I am the Loto instru

never mind.

Ahh - new website --> http://www.loto-ins.com/en/

Very much still around.  Hmm.

What a horrible web site.  It is so hard to find anything useful.  :--

Now I went through the whole OSCA02 story and reviews. Some are good or even great regarding the modularity and the logic analyzer, but here   in the forum the owon 1022i is still ahead and OSCA02 had not even made it in a tear down or deeper investigation.

Considering the time I had to spend to simply get into the whole idea of modularity it was painful. The webpage is outdated or feels so.
The first real usefull source was the ali express shop site and of cause after digging into it the link to the google drive were you had to get the specification pdf with 21 pages of usefull content.

What a huge amount of confusion and model variants - an overkill for a newbie I guess.
1 year later and the whole mess of complexity has not been solved.

The idea to sell a product in a windows version and for additional 30€ an android edition is also a big deal breaker not telling the people what the really will get: the free hscope version or a licence one with all its glory ?

Not a single line and it adds more complication than value instead of simply doing what other have done before successfully: supporting hscope

I first got the hantek 6022BL and I plugged into the USB a 20 cent otg adapter (I always have in my wallet to use any USB device on my phone) and installed hscope: worked instantly and great , also got the first success with the calibration ports

But I had to sell it cause what I had not known was that the Hantek is fully missing the AC coupling

I would have gone for an osca L having the additional benefits like
* USB 2.0
* 72h data logger recording
* decoding UART/RS-232/485/422, I²C, CAN, SPI, LIN
* broader bandwith

but those come at the price of other limitations escpecially when compared with the Owon as mentioned by gyro and others like

- basic edge triggering only
- no galvanic isolation - if you purchase the add-on adapter, price? about 40€ I guess
- The LA capability could probably be bettered by a low cost ebay LA and Sigrok.
- more expensive in case galvanic isolation is needed
- nobody's done a teardown yet!
– Time range: 50 ns/div ~ 2 s/div (5 ns/div - 100 s/div VDS 1022)
– Input sensitivity 50 mV/div to 2 V/div (5 mV/div - 5V/div VDS1022)

I guees it needs more than just a nice and big hello to bring devices into the market.
Sad to see that the last year seems like a lost year cause hard to find any reviews and further details where the OSCA02 was outperforming others like the Owon. Hope you will get back some time with a slimmer approach than with an entry model where you need to become a doctor to figure out what you need and at which price point like the ali express site and your data sheets which also still have bugs visible for an amateur like me.

It seems the team is actively updating the demo videos, on both BiliBili (42 videos this year so far) and YouTube (12 videos this year).
