Siglent SDS7000A 3, 4 and 6 GHz 12 bit DSO's
J_in_MN:
A video from Siglent that talks a little about the design decisions and differentiation compared to competitors.

Well, well,
I do not get any more blamed by any OXCO, before you measured it or tear down what crap you have!
In addition the final performance counts and the possible measurements as RIS or similar required.
At first, IMHO the base oscillator counts (any different as seen on the old LeCroy WM8xxx or SD6xxx series).
So as Siglent & Rigol are new on that Jitter Tools, a real tear down & compare with a reference would show up how the really performs.
Using various DSO as from Teledyne, Keysight, R&S, Siglent & Rigols & etc. The Jitter Tools setup is also not a easy task.
Its like a fast pulse, as real 30ps Rise time and lower DSO brands will show up false values.
Attached Teledyne Wavepro HD given figures as for me a better reference. :phew:

Being a WaveprovHD owner I well comparing 4Ghz 7000 Siglent shortly
I expect it to perform very well i may even purchase one when the Wavemaster HD arrives
The R&S MX05 is notb being this league its a well engineered and specifically designed scope for a different sector of the market
The MX05 is basically two 04's in one box with another 500Mhz on top its analysis tools are basic at best currently it's also 5GS/s not 20GS/s it certainly has its place no question.
But we are comparing apples to oranges imho
The internal claimed jitter on the Wavepro hd is 60pS with its internal clocks.

It is 60fs NOT 60ps, otherwise 20ps time scale would be unreadable...
The other question rises about the claimed 60fs RMS and it's PN figures. I expect here a 10MHz internal oscillator.

You are quite correct HP, I should have spotted that schoolboy error, in my defence I was using the pad in the small hours of the morning!
The Wavepro HD/Signal genny/RTA are also slaved to the lab's a 13.2fS jitter reference 10Mhz clock which is -123dbm @ 1Hz no distribution box just eight outputs from the clock direct. Even the industry standard FSWP doesn't have that sort of phase noise (or lack of it)
However the Siglent 7000's base line spec I don't know but I'm sure some one will enlighten me, the 7000 is due here in the UK before Christmas so I will be spending some time with one very soon.
