Maybe we'll get to see something from Dave.
As I said, I can't imagine it.
Siglent sees the 3000 series as a kind of entry into their "Pro" series, even if the "X" suggests otherwise.
I imagine their expectations of a review are accordingly.
Taking the thing apart and commenting on it, then playing around with it a bit to get the 20...25min full won't be enough to send a copy for it.
Of course, I could be completely wrong and he would have received one long ago if it was available.
Because that's the point, you can't get it at the moment, the last updated date was the end of May and I think even that is at risk.
