Here you go.
100 KHz 5ns pulse with 2ns risetime, fastest I have from a SDG6022X. Siglent 1 GHz rated BNC cable.
NO clock syncing, just 2 standalone instruments.
Dots and Infinite persistence.
It is quite obvious that there is no visible jitter for a digital trigger system with properly implemented trigger point interpolator and the screenshot with infinite persistence shows just that.
The measurements however, including histograms, work with the raw sample data, which leads to a fairly evenly spread distribution at +/- 1 sample period around the trigger point. So while there is no visual jitter and cursor measurements would be just fine, the standard automatic measurements yield valid results only if the average in the measurement statistics is used.
In case of the SDS5000X, we already have improved measurement strategies for frequency, period, transition time and cycle to cycle jitter. These can provide better resolution and accuracy than the sample period even without averaging. Any attempt to apply this concept universally for all time related measurements as well as horizontal histograms would require a lot of additional processing in many cases, especially considering the deep measurements offered by the current platform.
I don't think the 100ps jitter specification is really meaningful, since I've yet to come across a case where jitter becomes actually visible, even at 200ps/div. This is clearly some worst case specification "by design" and it's a peak value and not RMS on top of that.
That said, there are currently no plans to add an eye-diagram to the SDS5000X series.
