EEVblog #978 - Keysight 1000X Hacking

[skander36]

I don't think that it's that simple. Frontend needs substantial rework and sign gen section is  missing  quite a few components. Don't forget about the trigger too.

For EDUX to be recognized as DSOX and to receive the promise 200k wfs and serial decoding, indeed is only need to change the value of a two resistors as TK said.
The other modifications are needed for bandwidth increase , awg to work and hardware callibration to pass .
But still need to wait for rumors to be true ...

L.E. With Fercsa mod, protocol decoding work . And is only software mod.

[TK]

At the embedded world yesterday I was told that in a couple of days there will be a new firmware for the Non-EDU versions to increase waveform update rate to 200.000 /s and to always enable serial decode/trigger!
Now I'm waiting quite excited to finally play with the serial options on my 1000x

I just checked the release note and the free serial decoding seems to be only for the 1200X models purchased after March 1, 2020:

Serial decode and trigger is now standard for DSOX and EDUX models purchased on or after March 1, 2020, with the following exceptions:
o DSOX1204AmodelswithaserialnumberlessthanCN59356100willrequireserial option license(s) (D1200EMBA, D1200AUTA)
o DSOX1204GmodelswithaserialnumberlessthanCN59357100willrequireserial option license(s) (D1200EMBA, D1200AUTA)

Increase in wfm/s:

200,000 wfm/s for DSOX1200 and 100,000 wfm/s for EDUX1200

The 1000X firmware release note does not mention anything about changes in the serial decoding or screen update rate.

Bummer... That's to bad, I guess with my old one I eventually have to buy the licence...

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 !

[johnnieo27]

Thanks Skander36. that's good news.
Follow-up question for the group:

I read through a number of threads regarding some front-end hardware mods that folks have done, but it's not clear (to me) if they are needed in addition to the SW unlocking that the Fercsa mod enables.

[luiz_aug]

Taking a ride with your question, can someone help me compiling all modifications (HW + SW) to get the most out of an EDUX1002G v1.1?
I read most of the thread discussion, but it was unclear to me what was testing and what was the final mod pack.

I've postboned this for a while, but now with this quarenteen thing, it seems like I'll finally have some time to 'get my hands dirty'...

Hello friends, is it possible to update to the official firmware 1.20 with the Fercsa firmware already installed?

Thank you.

[wxqhigh]

You mean that you have tried the Fercsa mod on rev1.20 or over 1.20 ?    And it works successfully?
That's a really good news!
THX~~!

[Cesarsound]

No. Actually I have Fercsa installed on my DSOX1102G and I would like to know if I can install the new official update V1.20 on the Fercsa version.

[TK]

No, FERCSA's hack is a full self-contained firmware pack that replaces the one supplied by KS.

So，it means FERCSA's hack is also fit for the new rev1.2 or over the 1.2?
 It seems skander36(#655) had installed it.~~
THX~~

[TK]

FERCSA firmware is based on 1.10

If you have official firmware 1.20, you cannot install FERCSA as KS does not allow downgrade the firmware level

If you have FERCSA installed and install official 1.20, you will loose all the hack and you cannot reinstall FERCSA firmware.

Have you installed FERCSA’s hack on new rev1.2 ？
It works？It seems nobody tries this on rev1.2....except you~~~
I also have a EDUX1002A with new firmware 1.2..but I'm afraid to try it.... Because TK said it can't be installed~~
THX~~~~

To be more clear .
As I said before, Fercsa hack can  be installed over 1.20 rev and 1.20 rev can be installed again over Fercsa hack.
But only when Fercsa hack is installed you will have hacks efective . Installing official rev. 1.20 will replace all hacks . To have it again you need to put again Fercsa hack .
For EDUX1002A (as mine) the hacks that work are Serial decoding(CAN, LIN, FLEX, ARIN, MIL Std.) + training signals, Mask . For other functions you don't have necesary hardware. Segmented recording does not work . You need other hw id .
I hope this clarify this problem.

Fercsa hack let's you downgrade the firmware and you can install any version.  But it is my understanding that he never released any hack for version 1.20.  Unless his hack presents itself as a very high version number, that any KS official firmware will think it is a valid upgrade.

We might need confirmation from FERCSA.

I have not tested firmware 1.20 because I sold my EDUX1002G

[skander36]

People ask if is possible . Yes is possible .

[Fungus]

People ask if is possible . Yes is possible .

But you'll have the previous version of the firmware.

What do you mean ?

Wow,that's realllllly a good news~~~~~THX~~~

Do you have 1.20 installed?

Do you have 1.20 installed?

I'm going to try，I bought a EDUX1002A and it’s calibration date is 2019/08/26 ，so I guess it has the new 1.2 frameware.
It's still on the way~~~
I'll push the picture here if I have any good news~~~（Actually I hope it has 1.1 frameware ）

External trigger area, mysterious(no one measured it) cap under LMV7219

Is it on the other side of the PCB ?

Nope. Same side as most of the mods. Just look for U9 on this picture:
https://www.fercsa.com/keysight/trigger_mod_before.jpg
Then top-right, there is a 10nF cap. I used 10nF, because I already had one. Others used a 33nF cap, so that could be good too.

I tried 22nF and it didn't pass the self cal, so I'd say that 10nF is the maximum here.
