@marmad have you found any changes to security with the new FW, ie have rigol closed the door on down grading FW, DSA9 keys etc with the all the recent revelations lately its got me curious.

DSA9 key appears to work exactly as before.

Are you telling that Rigol calculates the rise time in wrong way?

Well if those cursors are auto placed, then I would say that's very poor placing.

Anyone else think the same ?

There in the picture is rise time from 20% to 80% measured with cursors as 840 ps.

Then rise time from 10% to 90 % can be calculated as Ln(9/1) / Ln(8/2) * 840 ps = 1331 ps = 1.331 ns, which is not far from by Rigol calculated value 1.32 ns.

No, cursors are not placed automatically. They are for rise time from 20%to 80%, which is 840 ps. Look at the table on the upper left corner. Rise time from 10% to 90% is at the under left corner and it is 1.32 ns.
darrylp:
Ahh yes, too quick looking at the picture and typing a reply. I see the delta x is not the rise time its measuring. Sorry my bad !
