Upgrade your X2000 or X3000 to the new 2.10 firmware. The noise you guys were complaining about is fixed. I'm satified and I don't have to tear into it and make all sorts of modifications on my DSOX3024. The new firmware also supports a USB Keyboard and they added an on screen "Annotation". You can also use Control codes to access functions like Cntl "T" for trigger or Cntl "U" for utilities.

Nice if Willco788 can come with some more details about what he found as fixed in the new firmware (noise problem).
There are two aspects in this noise case: 1.The software treating of the signal to filter out the eventual noise, or lower the noise level. 2.The hardware treating of the signal in the internal circuits, to minimise the (electrical/EMI) noise in to device it self.
I`m very sceptic about fixing by the new firmware of the hardware noise problems... If it was fixed something in the new firmware, an more minimising of the noise over the signal, then it is about an more (sophisticated/improved) filtering through the scope software... I personally do not think is a very basic solution (by software) to get in fact rid of noise problem. But an improvement is always welcome...

I`ve installed me too the new firmware. Related to the title of this thread, and to my previous post, I can say that it seems to me (after a quick analyse) that what is to be seen on the screen is a little bit different than before (in a positive way...). Else, on my device I could not noticed yet any change in the quite low figures I`ve get (concerning noise levels) than before installing the last firmware. If it will be confirmed that the new firmware have some sort of improvements in filtering out the noise over the signal, then in my already hardware treated device, may be not very much yet to be filtered out... This may explain why I can not register any change in the measurements (figures) of the noise levels after installing the new firmware...

Will be fine if many comments can come from another members here about possible improvements of the noise level after installing the new firmware. It will be nice also if Agilent it self can confirm/clarify if the last firmware come in fact with such improvements... In the firmware`s release notes I couldn`t read something about this subject.
Agilent efforts to improve their devices it is only to be appreciated anyway...

I don't think they actually reduced the noise. They did something in software to reduce the pixaltion.

Is also my opinion, that in the new firmware is about an improvement in the graphical quality of what is showed on the screen, or something like this... Related to this subject/case, an more cosmetic improvement... Anyway is positive!
At least the title of this thread do not "sounds" very real, I suppose...

The title of this thread state something which is not true or a fact. The author himself admit this. I just wonder why the author of the thread do not modify the title or just delete the entire thread...
I suppose, the moderator should do something to prevent that false informations are spread out in this forum. Or if any supposing noise problem it were fixed in this firmware, then Agilent should confirm/clarify this...

    Nice to see a correction is made in the title... It still now to be clarified what particular noise problem is in the new firmware, comparing with the old one...
    I personally mean that the noise (problem) is based in the hardware. A firmware/software can only filter out what is hardware generate. I just notice that the scope behave better after installing the 2.10 version. I can not yet explain very well why... But the noise measurements (by the scope it self) still be the same as before.
    
    I can see that quite many visit/read this thread, but no one else take the "risk" to have own opinions here, or comment the new firmware... :-(

      Normally I don't use the lower volts per div scale and for me, the noise isn't a problem. If I need to measure something in the low level audio range, I just turn on the BW limit. If Agilent ever provides a modification kit or even if I have to send it in, I'll have the noise reduction installed.
