(BTW, to the owners: I haven´t found the possibility to save all the screen content to the stick, when doing a screenshot, all open menus won´t be captured, so I must use a camera)

On the web interface you have menu "Print screen" . There you have both options Screenshot and Screen Capture.

Thank you but it should be also possible without web control..Something for the wishlist.
Not for me,but for the current and future owners.

(1.2ns when 2 channels are active).
When all channels are active, the overshoot of the pulse gets "blurried" while the risetimes decreases to 1.5ns .
Hm...

Sinc interpolation is supposed to introduce pre-shoot and overshoot, when applied to an undersampled edge. I guess the frontend is too fast to prevent aliasing at 1GSa/s and 2GSa/s. Is it possible to turn off sinc interpolation?
Martin72:
Just powered on again*, there is no possibility to do it.
*(When plug in the scope to mains, it will switch on for a second (fan starts running, display lit)before it reaches the standby condition)

No, you can't turn off sin(x)/x interpolation in these scopes, it has been confirmed by Rigol.
