--- Quote from: marmad on November 09, 2014, 08:43:32 pm ---No, the amount of noise won't make a difference: in High Res mode, it's already displaying the lowest intensity level possible. <snip> You can prove this by turning the intensity level to 0%, then running the DSO in High Res mode. It will always be a perfectly black trace. --- End quote --- Yup confirmed. But if the algorithm is so simple what would be the problem (for Rigol) to just upshift the intensity to get better visibility? If I understand you correctly there already is only one (1) intensity level in this mode, so no intensity information will be lost :-// |

As I mentioned, I guess some Rigol engineers thought it was better to keep it consistent to reflect the reduction of data by averaging when the DSO was running. But it would be nice if it was at least an option you could turn on and off (e.g. Intensity Averaging - or something like that). Since there is only one level at >=200ms/div High Res, you might as well set intensity to 100%. Do you still find it too dark if you do that? |

There is a new issue with 'Rigol DS1000Z & DS2000 Oscilloscope Jitter' related to the Trigger mode/method. See -> https://www.eevblog.com/forum/blog/eevblog-683-rigol-ds1000z-ds2000-oscilloscope-jitter-problems/msg550964/#msg550964 This is already up to 12 pages in only two days. I'm posting this alert here because I didn't see Rigol O'Scope experts here such as 'marmad', 'teneyes', etc there that could be valuable contributors to understanding the issue. And further we should all at least be advised that this issue is being discussed. I also believe that some DS4000 users are experiencing the trigger jitter issue (with the AC trigger mode). |

As I noted over in that thread, we've been talking about problems with AC-coupling the trigger for over 2 years now in this thread (check out the bug list or search the thread). Few of us original owners use that setting because of these problems - and I've never found a single instance in my use of the DSO in that time where I needed it. The other jitter being discussed is not present on the DS2000. |
