Why do you want that, there are 1.10 and 1.20 available now. 
Several people have told you LNK method  used for 2000X-4000X scopes is NOT working for 1000X. Connect a serial console to the scope and you will see error messages if you try using a Lnk file.

Thank you.
When I go into 1000X WinCE and 2000X WinCE,I find they have similar file structure.
So I am thinking why we can not add 1000X options like 2000X-4000X with link file.
Is there other segment in infiniivisioncore.dll or some file needing to change?

[Bud]

They may be similar but it does not work on 1000X. This is what you get if you try making a LNK file

There is no -l argument option available in 1000X.

Good luck if you still want it.

I learn more.

Can someone please share their EDUX / 1000X Factory Cal files ?  They are in  the hidden \Secure\Cal  folder. File names are or similar to :

ServiceCal.dat
FactoryCal.dat

[Bud]

Can someone help me with the Factory Cal files please  ?

There you go, they come from a DSOX1102G though, hope it'll help you.

[JDubU]

Well, I've tested the 1khz signal from another scope and it looks the same.
My bet is that somewhere on the front end there is a weird thing. Maybe the output filter (after diff amp)
Can someone confirm that on DSO1102 the filter has 47uH and 4.7pF?

Did you mean 47nH instead of 47uH?

[Bud]

Good catch, should be 47nH.

Thanks a bunch, it did help, more good stuff will follow shortly.

[liviux]

No, my typo I used this one: LQP18MN47NG02D 47nH

[JDubU]

No, my typo I used this one: LQP18MN47NG02D 47nH

2.2 Ohm series resistance is a bit on the high side for a 47nH 0603, but don't know how relevant that is in this particular circuit.

[Bud]

Another problem I found last time is a jitter on external trigger. Scope can't align trigger edge with time 0.

Can you provide details of a test setup so I can try to replicate ?

[Bud]

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.

Two errors spotted in the Excel spreadsheet components list and the PNG screenshot (refer to the quoted post for details). An updated screenshot is attached.

[JDubU]

Does a list exist for the 1000a --> 1000g wavegen components?

I successfully applied the 1.20 Hack made by Bud to my DSOX-1102G which had firmware 1.10 previously, it works like a charm! Great job Bud, congrats! Julio.

Hello! Thank you for the work you put into this. Would it be possible to get a re-share of the download? TIA!

Super, worked perfectly on my scope. Thank you kindly.

Hi all,

I just received my new DSOX1202G and i noticed the FAN is noisy. It makes a noise like "grrrr" not that loud but if you sit at the bench for hours it's getting really annoying.

It looks really interested that you managed to hack DSOX1102. Is there a hack available for the newer model DSOX1202? I see all the replies are mostly for DSOX1102

The DSOX1202G has temperature controlled fan and noise should go low after a few seconds after turning the scope on.
This scope is linux based and there is no software hack available

Thank  you for your fast response. Well it doesn't seem to go low after a few seconds, i have kept it on for 1-2 hours because i was working with and the noise was stable all the time. At least to my ears. The annoying thing is the noise type, it's not the air flow that you hear but something like grrrrr in higher frequency.

So for the linux version needs some further investigation.

...

In my experience, the high frequency "grrrrr" is caused by the turbulent airflow between the slot pattern in the case and the input side of the fan.  I modified my 1st gen 1000x by cutting out the slots in the case and replacing that function with a wire fan guard that is spaced farther away from the fan.  It almost completely eliminated the annoying high frequency noise and is now mostly just the lower frequency "shhhh" of air movement.

Here's a photo:

[candrian]

This is a good idea. I gave a try with a quick 3D printed grid having in mind to reduce the possible FAN turbulence.

It made a small difference but there is still some noise.

(There is a cut in half to the printed part as it was a quick design and there was a mistake in the distances but it was still a good fit for test)

[JDubU]

I wouldn't think that an added grill would help much.
I think that the annoying, higher frequency noise is being generated by the turbulence between each moving fan blade and the slotted grill in the case.  The sound would have already been created before the added grill comes into play.
As an experiment, try removing the back case of the scope to hear the difference (it's only four screws).
