I find the trigger jitter was specified 100ps. At the beginning, I assume it's a typo. But comparing the 2000X's 10ps-rms, they might specified in different ways. Doesn't know if they are on the similar level.
Trigger point is interpolated.. It's resolution will be influenced by vertical resolution (vertical part of the slope), sample rate (horizontal part of the slope), interpolated timing resolution (internal math representation) that will be dependent on timebase available....
It's fastest timebase is 2ns/div (opposed to 2000X+ 500ps/div) and worst sample rate is 250MS/s... So factor 10x doesn't seem unrealistic...
But... on my SDS2000X HD I get trigger jitter in hystogram to be about 220 fs RMS (yes ,
femtoseconds !!).... That is best case scenario, super fast edge, fastest timebase, single channel...
I can see that worst case could be 10ps RMS.
BY same token I presume whatever the spec for SDS1000X HD is going to be very conservative worst case spec... and could be 100ps...
Which by the way is spectacular anyways if you think about it.......
