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. |

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? |
