I did not discover anything new by "just" working with the usual functions. |

I update with FW 00.03.01.00.04 from 00.02.01.00.03... Bug 17) is still there... :( I took a look at the waveform update rates and here are my results. I used only 70kHz Sinwave to test because I don't have a SigGen... Sorry! |

Sorry! --- End quote --- Well, thanks for doing that, but your 20ns/Auto/Vector number is most definitely missing a zero. I'm getting 17,820 right at this moment. Also, your input frequency of 70kHz is close enough to the highest update rates that it might negatively impact some of those numbers. I've never seen anyone make these tests with less than a 1MHz input signal - to make sure there isn't any chance input triggers might be missed due to timing mismatches between the input frequency and internal clock. |

I have noticed that the waveform intensity of my 2072 in hires mode becomes significantly lower at low timebases. This is also the case if I use hires in roll-mode. It seems to happen if the timebase is > 100 ms/division. See attached screenshots. Basically the waveform becomes almost invisible in normal light, it is rather annoying. Am I missing something, is it a known bug? (could not find anything) My DS1074 does not exhibit this behavior. So I switch to that instrument when looking hires at low-frequency stuff... |

So you're basically just looking at a brighter waveform that is barely (if at all) being averaged. I just checked Roll mode on both scopes (@ 200ms/div), and the DS1000Z is definitely not averaging to 12-bits (i.e. no High Res) - while the DS2000 does it perfectly. |
