ClaveFremen · 17th July 2011, 12:35 AM

Someone has seen/buyed this oscilloscope?

NEW MINI ARM DSO203 4 CH Portable Digital Oscilloscope | eBay

Opinions?

Thanks in advance

We bought one. Nice toy.
But both hardware and software will need another year of development to mature.

If you are a uP guy then go ahead.
Everything is in the public domain. Codes are open source.

That is my impression also, it's a cute little toy for use as a maybe a front panel display or similar application, however like most inexpensive "'scopes" it lacks a serious "front-end" (vertical attenuation) for any sort of earnest test/lab application.

You are asking a LOT for your money.

Interesting review...

Yeah its not a 'serious' scope now but its looking good for the future. It won't be too long before many of the functions requiring external chips will be fully integrated in silicon. For example here's a taste of things to come in this area - it dispenses with the need for the FPGA in some data acquisition systems:

AD6641 | 250 MHz Bandwidth DPD Observation Receiver | All A/D Converters | Analog to Digital Converters | Analog Devices

Next up this part will get integrated with some on-board ARM Cortex CPU I'm betting.

Hi.I bought one and it came several days ago.But there is no file on virtual flash and i copy and paste some of hex files but it does not work.Does anyone know which files should i copy into this virtual flash by order?I am not experienced in microprocessors and firmwares and no help documents came with the box.There are many documents on internet many different versions of firmwares but i could not work it.
Here is the screen.Can anyone help?Thank you very much
