I have to admit I haven't, I tend to do everything via ethernet as it's just easier in my setup.
I will probably have to move over to USB, assuming that is OK, to keep things running until I get round to sorting things out.

Rigol got back to me and asked some follow ups, including shipping information. Made sure I was running the latest firmware, etc.
It's very odd. I wish I knew what was causing it. It sure sounds like the LM317 issue, but mine is well after they fixed that. It also sounds a bit like some software watchdog bug...
Anyway, I'll post back when I hear more. If it was easier to reproduce, I'd be troubleshooting a lot more, but just because it runs hours without an issue doesn't mean it's fixed. =/ And since it's under warranty, I don't want to crack the seal to monitor the LM317 or CPU reset pin...

Not a lot of DP832A threads on EEVblog.
I was wondering if these issues have been fixed in the latest PCB/design/firmware revisions?
1. Easy to overload pass mossfet
2. Do people still prefer the DP832 instead of DP832A? Does DP832 have all the updates PCB/design wise?
3. Where's the DP832A hack thread to unlock more resolution? I saw the "Sniffing Rigol's Internal I2C Bus" thread, but that's like >160 pages, not realistic to go through that.

1 - The 832 and 832A use exactly the same PCB, so all PCB/Design updates should be on both. The MOSFET issue has been resolved on the latest models as far as I know.
2 - The preference between 832 and 832A is mainly just visual. A hacked 832 offers everything that the A offers without the Eye-cancer inducing colours.
3 - The hack doesn't require any I2C sniffing or opening the device. Just use the riglol software to create the keys you need.

There are no options on the DP832A to be hacked. The DP832A is just a DP832 with all options already enabled.
