Help me choosing new Oscilloscope

Hello everybody,

I have no decided yet, but I'm looking around to see which is suitable for my application. I had in the past the DS1054Z unlocked. Recently I've sell it on eBay trying to upgrade my bench.
In general I do not use scope for "fast" signals (I have never measured signals faster than 10MHz) but just for power supplies ripples, data bus, and so on. Never used for any kind of HF application. So my question is, can you help me choosing ?
My budget: 1000-1500€ and I have seen the MSO5074 and the HDO1074. I know they are pretty different from each other, but thinking about the future I don't know which is the "best" choice. I know that MSO5000 have huge sample rate with respect to HDO1000.. but is it really important?

Thanks in advance for any suggestions.

"Data bus" implies a digital waveform implies you are measuring fast signals. Hint: the clock rate is irrelevant: all that matters is the transition time.

FFI, with a little theory and some demonstrations: https://entertaininghacks.wordpress.com/2018/05/08/digital-signal-integrity-and-bandwidth-signals-risetime-is-important-period-is-irrelevant/

We know even less about your future than you do.  :-//

HDO1074 is best for power supply ripple.

MSO5074 is best for data buses.

What sort of power supply ripple do you need to see? Are you worried by 50mV, by 5mV or by 0.5mV?

That's pretty interesting article! Thanks a lot.

Good point. The answer is that I don't know  |O
Basically I'm looking for a valid upgrade. Usually 5mV is sufficient on most of my application.
