That’s my stop.
This engineer is determined! Built a test circuit to identify one part.

You probably already watch him, but Marco is also great when it comes to similar content (he loves his multimeters) https://www.youtube.com/@reps
I have one of these scopes, with exactly this issue after a long period in storage. When I was looking into it a few years ago the failure mode was known but I couldn't find a recovery procedure. I'll need to give this a try when I get a few hours. I have been putting off getting a new scope in hopes that I could repair this issue.
Flash memory bits wear out after 100,000 to 1,000,000 writes. Thus, file systems must keep track of the number of writes and have a strategy to avoid wearing out storage, such as by moving popular data. —Patterson & Hennessy, P.23 Computer Organization and Design 5E
That quote would've been true in the 90s or early 2000s at the latest. These days it's more like 100 to 10K cycles for most mass storage flash, with the majority trending towards the former.
This is very interesting. I just have one minor nitpick. Broadcom did not buy Avago, Avago bought Broadcom. They then changed their name to broadcom as it was more recognizable in the industry (while keeping their old stock ticker AVGO as that was more recognizable in the financial industry). This is entirely a tangent but the rise of Avago from a minor second rate spin off from a spinoff from HP to one of the bigges…
Oh wow, I was just transplanting some TC702 amplifiers to save the doubler in an old 50GHz HP signal generator... would that have been designed by these guys back when they were part of HP? https://www.keysight.com/us/en/assets/7018-04165/application... EDIT: that's registration-walled, but this HP Journal article isn't. https://archive.org/details/Hewlett-Packard_Journal_Vol._42_... The amplifiers in question are bl…
> the MSO adapter can accept low power signals up to 40v, but it offers no input protection when the host oscilloscope is off. Thus, if the DUT (Device Under Test) has a short of some kind near the area of probing, and the host oscilloscope is not powered, there's a good chance you've just damaged the Maxim MAX9201 comparators in the logic analyzer section of your scope! It's worth checking all 10 pins for voltages o…
