>> SSA 200Hz Span & 1Hz BW and synthesizer jitter (also wobbling)
The plots where also given on a SSA thread, currently do not find any more... even with search.
May split the board into engineering & bug tracking and hacking
This plots shows the analysis of its own 10MHz reference source. Same as using a 10MHz 120dBc@1Hz OXCO. This means the
limitation is the used synthesizer.... just as similar is used on SDS2K so the plots went here in.
I used my Tek Scope 2464B (400MHz) and shows up about a 1ns rising/falling edge with some more overshoots as seen on a Keysight MSO3104. All signal used by a SMA & 50E connections. Even the active FET probe as 1G /3pf shows more overshoots using shortest connections. Output is OXCO & TI buffer driver, as spec's about 700ps Ts/Fs.
The question rises about the required samples at the slopes.... IMHO about 5..10 samples to get any accurate about slope and overshoots. While new on DSO, but get the feeling about a required 20Gs DSO for 1h measurement ... XX-K$ to spend or better to rent.
So using a SDS2K model with limited synthesizer precision's and channel behaviors (I guess as from the SSA model) a Sampling Scope or xxGs DSO with nice jitter measurements
Just to understand an 1ps variation is at one Terra Hz
