Have there been firmware updates?
Are they still improving it or is it not longer updated?
about the ARB mode:
I'm not really sure yet what Rigol is doing with the given settings.
I assume I can interpret it as resampling on a different frequency?
For freq X, points Y[] gives you all the points in time, then it gets resampled at 500Ms/s
(I can reproduce that with matlab)
And in step-by-step mode a fixed freq of 500MS/s divided by 16384 is used to have an exact match with the resampling hence no jitter or skipped points.
But there are more frequencies without jitter, all multiple periods of it.
Correct?
It's itching to place the order
edit:
Placed my order for a DG4102
(in stock) although there are things I don't like, there is nothing better out there for this price now. (968 Euro incl. VAT)
