Someone blew up one channel of our very expensive Keysight scope at work last year. Never found out who did it; Keysight repaired it under warranty.
Someone blew up MY OWN MSOX6004A at work without letting me know (but I watched surveillance and know who he is). He then graduated and fled.
Keysight replaced its acquisition board under warranty, so I didn't pursue further.
Grrrr, people can be so dumb. On the bright side, ours also got fixed for no charge AND proper use of the thing is going to be included in the mandatory training that will be required, no exceptions, for using the lab once they finish remodeling.
If you use common sense and the right tools you won't blow it up.
And a fixed 10x (or 100x) probe - none of that 1x rubbish.
Yeah, and an HV probe too. I have a couple of Tektronix P6015s...sadly out of Freon but 1000x divider if you respect the frequency derating curve, and still quite useful with the derated spec when not filled with a dialectric fluid.
