New Rigol DS1054Z oscilloscope
bd139:
I had a couple of spontaneous reboots when I had a DS1054Z so perhaps it’s semi normal crashing (crappy software triggering the WDT). If it’s doing it constantly though I’d be suspicious.
TurboTom:
Considering the DS1000Z contians the same application processor (Freescale IMX283) as the DP800 series of PSUs (which is notorious for rebooting unexpectedly), maybe the reason is identical as well. So it may be worth reading on @T2's findings and his suggested cure for the problem. Just an educated guess on my behalf, though. My DS1000Z never crashed without interaction, and even with me fiddling with the knobs, it only did so with rather early F/W revisions :D.

Weird that nobody else's DS1054Z is rebooting from that exact same software, don't you think?

That's a pretty poor statement to make really and a terrible terrible thing I hear a lot of the time from engineers. "it's only you who has the problem". At the same time, they're saying that to 100 people or aren't communicating between their account managers or support personnel properly.
If you consider the following which is usually the case from the last 20 odd years working on software and embedded systems...
1. Lets propose 100% of devices crash occasionally.
2. 10% of people report that, which is a realistic figure.
3. 10% of those people actually bother to respond to the ticket they opened.
4. 10% of those people actually help the manufacturer through debugging.
Say you sell 10,000 scopes, it looks like 0.1% of your userbase is crashing to the engineers. Most people say "fuck it" and power cycle it.
If you have a problem with 20% of your product base crashing, then that rounds down to very little data other than usually one pissed off and fuming customer who will tear you a new asshole the moment you say "weird that nobody else's DS1054Z is rebooting from that exact same software, don't you think?
Incidentally my DS1054Z issue was resolved by updating it in the end so clearly they managed to finally get that info together...

This thread alone has 4500 posts. How many of them report on spontaneous crashes of the DS1000Z?
