2 GHz scope: Rigol MSO8000 vs Siglent SDS6000
frankvh2:
I'm looking at buying a 2 GHz 4 channel scope for my workplace and would appreciate any comments or suggestions on the subject. The scope will be used mostly for measuring fast digital signals, and as part of the initial purchase I will also buy two single-ended FET probes. The contenders are:
Rigol MSO8204 scope, plus 2 x Rigol RP7150S probes
Siglent SDS6204A scope, plus 2 x Siglent SAP2500 probes
The package cost of either option is almost identical, at around US$15,000. Hence cost is not a factor in choosing one vs the other.
I am aware there are threads for each of these scopes. But if anyone has used both, or has opinions on why one is better than the other, I'd love to hear it.
Thanks.

What fast digital signal? Most of fast digital signals today are differential...Single ended probe is not optimal for those.
What speeds? What risetimes?
Both of these scopes are decent devices. As tv84 said, Sighound36 has MSO8000 and also used SDS6000A. He might be able to directly compare them. Both devices will do standard things, eye etc.
I did try MSO8000 shortly but never used it for real work. I can't really compare them directly because of that. I do use SDS6000 series scope and like the concept. I think they will basically be roughly comparable on basic features, Siglent is a little newer and has some options Rigol does not (and vice versa). If you have questions about Siglent I might be able to answer.
But since this is not entry level money (with two active probes ) you should really try to see if you can get demonstration or trial device to try it out.
Sighound36:
Have both scopes, the Siglent is better for tighter low noise power measurments, bigger screen. The Rigol just has more horsepower, small screen, but I like it's gui and its felxibility & apps. Both are good scopes, and deliver a lot of bang per buck as you chaps across the pond say. The digital logic channels are useful tool.
Recently I've gone all Lecroy in the lab, still run both Rigol & Siglent in home labs both on the audio side.

That's a bit brief.
Boot time ?
Fan noise ?
Memory/sampling management ?
Which maintains best sampling rate/mem depth with all channels active ?

I'd look at a used Lecroy with a bunch of software options for this kind of money.
I agree with 2N3055 here: a differential probe is much more useful to look at high speed signals. Especially since many of the high speed busses are differential nowadays. And using a differential probe as a single ended one, makes grounding the probe easier.
