To power it, I'm using SigRock/Pulseview[3], which sees it as a compatible clone. It's wild to be able to see signals a few tens of nanoseconds wide so cheaply.

The new Rigol DHO800 series are fabulous bargains for the money, and extremely well designed in a lot of ways: - 12 bit ADC frontends - Actually usable touchscreen inputs - Super simple to drive remotely over a network connection (though getting the IP address with just the touchscreen is a little tricky) - USB-C power input - you can run it from a battery pack if you like! - All the essential decoders built in for f…
These start from 450 euros.
Maybe a bit pricy for the hobbyist.
This is crazy. The ones we used in the Navy were heavy and delicate. Now it fits into the palm of our hand. Just incredible how far things have come.
The cool thing about this one is that it’s open source and well documented.
There are a lot of downsides: The front end has poor input protection and the entire unit is much less resilient, calibrated, and trustworthy than what you’d use in the Navy.

I think projects like that would have been a godsend 2-3 decades ago, when even a basic oscilloscope costed as much as a used car. Nowadays, very good oscilloscopes with 200 MHz bandwidth, good user interfaces, and responsive displays are selling for $300 - I'm talking Siglent, Rigol, UNI-T. So the merits of DIYing something much worse just aren't quite there. It's that one piece of equipment you use to troubleshoot…
> very good oscilloscopes with 200 MHz bandwidth, good user interfaces, and responsive displays are selling for $300 This is a very strong first world POV. Those U$D 300 rank pretty high across world's minimum salaries [1], not to mention that prices can very likely double in countries like my own. Moreover, a large % of people that can really get a very good use of this (Kids in high school) usually have a lot less…

For about the same price ($13), I'm happy with this logic analyzer I bought through amazon[1] a month ago. I spent more on probes[2] ($24) than I did the analyzer. ;-) To power it, I'm using SigRock/Pulseview[3], which sees it as a compatible clone.

We're all looking to do the best we can from different baselines.

I'm an old timer so I'm familiar with the traditional scope front panel, but have come to like the touch screen for changing settings.
Perhaps my only gripe is how long it takes to boot.
