Do you have some experience with fan replacement in 1000x? I'm looking for silence one.

I swapped mine for a Noctua fan. It’s a fairly simple task doesn’t even need breaking any seals. It’s still quite noticeable, but not nearly as loud as the original one. I later got another 1000X which already came with a much quieter fan, maybe just a little bit louder than the Noctua one. I feel like most of the noise is actually coming from the air being pushed through the vents, not the fan itself, so there isn’t much you can do really to get it super silent. But if anyone had success making a super silent 1000X, I’d be happy to hear.

I also switched to a Noctua fan (NF-A6x25 FLX) with the same result.

Since the air turbulence through the narrow fan guard slots in the plastic case is making most of the noise, I made the modification shown in the photo.  Much quieter!
It could possibly be improved a little bit further by doing the same mod on the air outlet vents (on the right side of the case) but I didn't want to go to that extreme.

Hi,

This is my unassuming contribution to this thread that Dave started long ago. I'm sure that if he had had access to this table his life would have been a lot easier (but surely less fun!).  Nonetheless, and for historical/reference reasons, i attach below a table of all the IDs that the 1000X app code (WinCE and Linux) accepts.

(Don't bash me, i know that most of this information is now old news for the more knowledgeable.)

My analysis is based mainly on the appcode analysis and validated with all the information shared by all of you throughout this thread (specially with the videos that started all of this). Unfortunately, I don't have any of these instruments.

All the Product_Configs that are not in the table have no significance whatsoever and result in invalid configurations. (As you see, there aren't so many scenarios as one might think.)

As you all know, executing the resistors_mod sets the voltage levels read by ADCs 0-7 (ADC 4 value is not used anywhere in the code).

Of course, one thing that is possible to do with a software patch, that the resistors_mod is unable to achieve, is that, by tweaking the table params, we can further change the behavior of each Product_Config setup. With that we can try different configurations that have not been tried before...

I marked in red the 2 cases that Dave found strange in his video and the parameters, that in my analysis, affected them. For example, further sample rates of 2.5GHz could be attempted by placing 0 in the SampleRate field of the "usual" Product_Configs 21-24.

It's also perfectly visible which are all the configs "FPR (Final Production Run)".

WinCE versions only go up to Product_Config 27. The remaining ones are only visible in the new Linux software.

As a final note it seems the famous "Baldwin" is a reference to "Matt Baldwin" (whoever he is), according to some info inside the app.

If you see any errors please report. If you would like to test some software tweaks, maybe I can help.

Hello, this is my first post.
I have a DSOX1102G with firmware 1.20 and by reading these threads I understand that the Fercsa mod. is for rev. 1.10.
Is my assumption correct, or have I misunderstood? Is here is a solution rev. 1.20?

ps I can't seem to find rev 1.10 anywhere. Perhaps once rev. 1.20 is installed, there is no downgrade path.
Thanks in advance for the help

Yes you can load Fercsa version over 1.20 .
Please be patient , update wil take more than2 minutes .First splash screen wil be a red bug and after that Keysight splash .
In Help-About you will see all kind of licenses loaded .
Good luck !

It is useful for DSOX1102A,but not DSOX1102G.
If your DSOX1102A has 1.20 FW,you can use FERCSA file to hack it.
If your DSOX1102G has 1.20 FW,you can not use FERCSA file to hack it

FERCSA file is also useful for EDUX1002A.
If your EDUX1002A has 1.20 FW,you can use FERCSA file to hack it.

I see somebody using modified file to hack 2000A 3000A 3000T 4000A OSC,these files modified  Infiniivisioncore.dll.
but FERCSA's file didnot modify the Infiniivisioncore.dll.

Here is my contribution. The list of components to replace in the front end (both channels), trigger, product code, and three more resistors (display, edge adj and ext view) .

I also attached a few images from our colleagues in a different organization.

Moreover I'll update the list with the signal generator.
