No it's not. 2k for a fully unlocked scope is not 5k series money. Not even close.
Fully unlocked RTB2000 is very good price if you can get one.. Agree..
To the OP: I think you should keep in mind that it's not about the features. My advice is: don't listen to the gearheads. They will tell you that instrument X has better specs here and instrument Y has better specs there. That doesn't help you because you don't have any specific application in mind. At least you didn't tell us.
So, what are you paying for? The UX. It's for your hobby, so the question is: do you LIKE the instrument? Do you feel good with it? That's what you are paying for. Don't buy something because someone says "it has better noise specs" if you don't like how it feels in your hands. I am pretty sure that some borderline specs don't matter for a hobbyist who doesn't do any specialized things. A hobbyist wants to have fun with the instrument, so use that one that is fun for you.
Both the R&S and the Siglent will pretty much do the job, so the only question is: to which one do you feel attracted?
I personally use the RTB2004 (all options) and are very happy with it. Of course it has some quirks, like every instrument.
You speak like it's a girlfriend, not a scope...
.
Jokes on the side, if you read again, I specifically said capabilities.... I don't care about features that are only on paper.
I understand what you're saying, I was looking at Rigol MSO7000 and wasn't impressed by baseline noise and general "feel" of the instrument.
If RTB2000 is good for all your need, I'm very happy for you.
RTB2000 has nice math (it didn't initially but was added later). Decodes are nicely made. I really like bit pattern generator.
When fully unlocked it is a nice scope.
OTOH, it doesn't have histograms (very useful), TIE jitter measurements (very nice), 50 Ohm inputs... etc etc..
SDS5000X is an instrument one level up in capabilites from RTB2000. It is not as refined visually (yet?) as RTB2000 in look and feel, but nevertheless very good user experience. It might not look so fancy, but it is very good. Unlike Rigol that is sometimes laggy and, in my opinion doesn't have most useful screen layout. But, if I had it on my desk, it would do the job. You simply wait a second sometimes and that's it. If it's for hobby, even more important to not spend equivalent of the house just to poke some signals every now and then...
If I were OP, I would buy SDS2000x+ and be done with it. For a hobby, even that is total overkill.
And for the rest of the money, invest it in good soldering equiment, microscope, some multimeters maybe, PSU, and most of the all, materials for my projects..
Because it's all about equipment that allows us to do projects..
Otherwise it is "instrument collector" hobby, not "electronics" hobby. Nothing wrong with that, mind me, but just saying...
