It would be interested to see if the fuzzy traces with 2 channel at fast scan rates shows on the Siglent like the latest DS2000 FW. With and without SinX/X?.
On the Rigol it seems to me to be related to SinX/X and intensity levels. That have changed on latest Rigol firmware releases.

No problem, Teneyes. I have the Siglent for a couple of more days, so I can post some images. Can you please tell me exactly what you want to see; e.g. test signal, timebase, etc.?

Teneyes:
A while back , WIM13 noted that the traces are a bit more fuzzy when 2 channels were on after the last few FW updates.  This is with FW 00.03.00.01.03

1 , 2   Bellow I show Chan 1 Only in Vectors and Dots with 70 MHz sinewave input

3 , 4   I then show both Channels 1 & 2 on, in dots and Vectors

5       Then I show a close up of the input and the noise appears to be some sort of sine wave on the traces
6        50msec Persistence

Could this be SinX/X extrapolation??
It would nice to be able to turn off SinX/X .

or is a change in the Intensity levels with no change in the min. persistence calculation?

Teneyes:
Fuzzy Traces
here I show fuzzy traces at Persistence settings of   Min,  50ms,  100ms  , 200ms. 500ms
It looks like Min. Presistence is set to an incorrect value!!!
and is about 200ms
