The Owon SDS1102 is a no-nonsense 100Mhz 2 channel oscilloscope for the benchtop. Here we go through the opening and initial testing of the scope. Quite impressed.

In addition to the information in the video I now know that the USB connector on the front is for storing snapshots.. and on the right hand side is a USB connector for connecting to the PC. Sadly, the version 1.x software that came with the scope does not seem to want to talk to Windows 10 64 bit USB. I'm awaiting a link for the 2.0 software and will report back in the blog. I'll also have more up to date information as I'm waiting for a precision reference and a new signal generator.
At the slowest end of scanning the scope is able to handle 1000 seconds per division - something checked and verified overnight as I set my Feeltech signal generator to 100 times faster than it's slowest speed!!!
Update July 2020: Comments welcome from readers who own one of these SDS1102 scopes - does it work well for you? In 2019, Elektor magazone reviewed this scope and seemed to verify the 1 Gsamples/s (500 Msamples/s when using two channels) and an input bandwidth of around 100 MHz.
Other reviews are a confusing mix of everything from likes to utter hatred so I'm happy to hear back from people who have actually spent time with this model as against those with a general dislike for inexpensive Chinese scopes. I can't update my own thoughts as I no longer have the scope, not for any negative reasons, but I have several other models and so this one ended up in the hands of a colleague. I only have so much room in my office/workshop.
