All scopes are a jack of all trades though. They're mostly useless in the frequency domain, the time domain isn't all that accurate either and the voltage measurements aren't that good really. This is why we have DMMs, frequency counters etc as well.
However it's the only tool that does all of the above at the same time and draws them on a pretty picture and in this case allows it to hang around longer than the phosphor would :)
The bugs that remain for me in the Rigol are the shitty FFT implementation, some UI lag, naff probe coax and the DC drift that plagued my last unit resulting in a self cal needing to be done every week.
The big non bug is the price, crackability and the fact it has an ethernet hole in its bum.
Tradeoff really which it still wins pretty well. Keysight's offering I was looking at was about £1300. Versus £370 it's a no brainer. Siglent is pretty good there too (nod to tautech) but the distributors in UK are shit so you have to buy it from EU which has a worse statuatory warranty on it than if you buy it here in the UK

I thought that was the last thing a redneck said before death overtook.

I believe that in the canonical form the words "Hey y'all" are required to appear somewhere. Something along the lines of:
"Billy-Bub, hold muh beer. Hey y'all, wuch this!"

My turn for a crap out. The recently purchased 2465. Complete power loss. Shit! Check the fuse and it's OK. So I tear it apart. I have AC power in. The EMI filter is OK. No blown caps. But no mains AC to the primary rectifier bridge at the input of the DC bulk for the switcher. That's strange. Finally found the culprit. The power switch itself. It's a DPST switch and one side was open. So as a temporary measure I jumpered that side of the switch and the scope powered up. For now it's fixed. But I really doubt I'm going to find the proper replacement switch unless I rob it off a carcass. So I'm thinking about a more permanent solution.
While I had the Regulator and Inverter boards out I looked them over real good. They both have original factory caps. No bulging or leakers that I could see. But I'm now definitely going to order replacements and get it done soon. And figure out what to do with the power switch.

Does that have one of those schaffner filters in it? I'd swap that out if you can if it does. That'll be the next thing that blows up and they go off in style.

I would like to apologise for the toast incident. I have punished myself by eating toast last night and this morning :-DD

Nah this is Telonic. They're pretty good. Next working day delivery with one hour delivery slot for free. The free meter is a "how can we screw someone for another 8 quid and use the word free at the same time" pitch.
Talking of which my new scope is due to arrive in the next hour :-+

We do not speak of the toaster incident.
