I've confirmed with Rigol tech support that DS7000 has the same "feature", only 10ns/div scale gives 680,000 wfs/sec update rate, any other time scale it is at least 5 times slower.

To me the most interesting question is how they managed to speed up the firmware for only one horizontal setting but not others? It's like making a car that can drive 5 times faster on only one road.

Maybe that's the only real HW rate the scope works on. All others are calc/emulated in software.

10GS/sec*10 nsec/div*10 div =1000 points. The display is 1024 pixels. So it could just write horizontal scale directly to display.  I am wondering about anti-aliasing/bandwidth limiting filters though, seems like they would be more time consuming than simple scaling.

Comming back to the self-calibration issue: Does someone have informations what the failed self calibration after the "liberation" patch means? Are the analog channels still correctly calibrated, even if the logic analyzer part fails?

The new firmware version v00.01.03.00.01 has been released. I don't know whether it can be hacked.
