Why the trigger jitter is not specified in the datasheet for the DSO-X series?
I can't find its value.  :-//
Thanks.

My English can be pretty bad, so suggestions are welcome. ;)

I just tested, original Firmware 2.36 did not work for USB boot, just resulted in cyclic blinking of the buttons with no software being started.

Then, I "updated" to the latest firmware available from the Agilent homepage (2.35) - as suggested by the scope itself.

Now, USB boot works perfectly fine.

Stick is a SanDisk Extreme USB 3.0 16GB.

Thanks for testing!! There were several user who affraid to downgrade scope to 2.35. Was there any warnining message?
Prior downgrade I reccomneds to reset scope to factory default, this help during my downgrading experiment with firmwares prior 2.35.

USB boot loops on 2.36 because of file versions mix I guess. It's no a true boot actually, the OS (and all files in OS directories) from internal flash is used, just the scope app is started from USB, so a mix of 2.36 internal and 2.35 external files occurs.

Somebody with that dreaded 2.36 should pull it out via telnet or USB stick batch copy script for study.

Neither problems nor warning messages at all. I expected a message like "you try to downgrade your scope" or "the latest firmware is already installed on your scope" but none of them appeared. I copied the cab file onto a USB stick, followed the original software "upgrade" procedure on the scope, then it copied files for 2-3 minutes, rebooted and the 2.35 version OS started without any hazzle. Also calibration is still fine. I think, it resets to factory default during the "upgrade" process, but I can't confirm.

Digging around in the software I found an interesting thing...

Dealer ex-demo scopes with all options enabled have a time limit of 9 months on those options.

The expiration date is built in the key, it is not related to the comandline parameter

It should be LAN module for 181 USD
http://www.home.agilent.com/myagilent/faces/partDetail.jspx?partNumber=75019-68705&imageStatus=NO&_afrLoop=1455775011571000&_afrWindowMode=0&_afrWindowId=null#%40%3F_afrWindowId%3Dnull%26_afrLoop%3D1455775011571000%26imageStatus%3DNO%26partNumber%3D75019-68705%26_afrWindowMode%3D0%26_adf.ctrl-state%3D39lnsndix_58
Wait, so Im confused. That LAN module you linked to says that it was replaced by the DSOXLAN-FG, if I already have the DSOXLAN module in my MSOX2024A does that mean that there is a new/updated LAN/VGA module. The link for the DSOXLAN-FG module says: "This part is not available for direct sale but an instrument repair is orderable through our service center. Please contact Agilent to inquire about returning your instrument for repair."
If at first you don't succeed, redefine success!

I wonder what's changed, FG can't stand for Function Gen so what could it be?

I just contacted Agilent on the DSOXLAN-FG module and apparently those links that were posted were not supposed to be exposed to the general public. He explained that the DSOXLAN-FG is a part reference for the entire assembly that is sold to us as the DSOXLAN. He said there is nothing different about its merely an internal part number.

Thanks for check, I just post it when I found it on website.

My DSOXLAN modul that I have ordered from Datatec a couple of weeks ago was marked with DSOXLAN FG.
 
@abyrvalg
Yes I'm also interested for a 2.36 Firmware packet to look inside the core dll

Also i have prepared a raw image with the Keysight Logo to replace the megazoom screensaver logo but until now i didn't had the time to change the data in the dll :)

Hi folks, I'm going to take advantage of the Agilent promo --- I have ordered a DSOX3k + LAN module.  The items are back-ordered 4 wks, so it'll be a bit of a wait...but I expect it to be loaded with v2.36 firmware.  Following what I've read here, I will telnet in, copy the files to a local USB, and share them here.  Hopefully we find a way to make v2.36 work from USB boot with configured options! Thanks people for all the ideas shared so far!  :)

Well, since we know that works already it is easy last resort.  I think it will be fun to try 2.36; several people are curious to see the core dll, so I can help with that effort.  And, eventually 2.36 might be on Agilents website for download.

I'm still trying to get the modified 2.35 version working on my scope. :(

Finally got it to work using a podunk 4G USB stick I got from Digikey for attending some training from ST Micro.  Go figure.

Hi,

I just wonder if I miss something?

Base on the Quote from: plesa on November 03, 2013, 10:24:37 PM

Instead of moving the startup on the USB key just live on the local disk

How to hack the firmware
1. Unpack the firmware *.cab by 7zip
2. Unpack infiniiVisionSetup.cab ( e.g. with WinCE CAB Manager 3.0)
    Find \Secure\infiniiVision\infiniiVisionCore.dll
2a. copy infiniiVisionCore.dll to infiniiVisionCore.old
3. Change at location 0x277e50 in infiniiVisionCore.dll
    byte sequence 04 00 a0 e1 to byte sequence 00 00 a0 e3

To reverse the change infiniiVisionCore.old to infiniiVisionCore.dll
Restart ...

Well only time will tell I suppose. We'll just have to hide and watch what they do.

I believe that would work, and you could also overwrite the infiniivision.lnk file with the original.  But, I haven't tried any of this yet...still waiting for gear to arrive.

In any case, you would want to make sure you have a failsafe USB boot key in the event something was corrupted on the local disk, and especially if you don't have the LAN module, as you might be unable to boot the scope and/or be "locked out" of it in some way and unable to resolve the problem.

Muahahaha! :-DD

Here is it the Enterprise Screensaver.

I did take a look in the dsox4000 dll and there are a lot more debug information and resources.
I opened the 4000 infiniivision with a resource hacker and I was able to extract bitmaps and Winform dialogs.
After disassembling the dll I searched for the text TREK and found the reference to this in a subfunction with other references to ...Screensaver...
So i tried it on my scope and bingo.

Regards
Kai

Today i was at the embedded world fair here in N├╝rnberg/Germany and i could try the Screensaver Easteregg with the text TREK which will work as seen in my video.
After I started the Preview it will show some credits.

It was a little bit sad that i didn't have a possibility to make a video of this.

It would be nice if someone which have a DSOX4000 available take a video of this easteregg.

It's coming next Wednesday (March 5th)! :)

Edit: It has arrived! Niccceeeee! As expected, it has firmware v2.36 on it.  The DSOXLAN module has shipped separately, so I need to wait few more days...  Will update again when I have everything!

I can add that the DSOXLAN module that I bought (from ZoroTools) was labeled "DSOXLAN-FG"; it came in a legit Agilent box, sealed and well packaged.

My Agilent DSO-X 3034A arrived earlier in the month and it took until today to get a DSOXLAN module for it.  The scope is running v2.36 firmware as has been the case for recent folks. It's been a pleasure to use so far, and I'm looking forward to unlock a little extra potential.

For the purpose of exploring v2.36, here is some details (for the complete file listing, see attached FileList.txt):

09/13/13  11:10a                      180736 infiniiVisionWebCom.dll


The infiniiVisionCore.dll is the same size (in bytes) as the previous v2.35 release, however the two files are different

The bytes previously mentioned to patch at location 0x277e50 are not there.  My best guess (just by comparing, and noting the same sequence of bytes) is that they are now at 0x277e30.

I patched the bytes at 0x277e30, and setup the USB boot key as per the instructions here.  I tried 3 different USB keys: SanDisk Cruzer 2GB, Kingston DataTraveler 4GB, Transcend 32GB.  All were USB 2.0 drives, and formatted FAT32.  None of these drives worked.  During boot, groups of LEDs on front of the scope would flash in sequence and after a short while the scope would restart and try again.  Removing the USB drive, the scope would boot as normal.

I am not sure if I patched the infiniiVisionCore.dll correctly as it is different to v2.35.  I have uploaded the .dll here.  I hope a more knowledgeable person could look at it and provide some comments.  If more files are needed, just let me know. @plesa @abyrvalg hoping you guys might be able to take a look.


Reading back through the thread, people have had success with:
"a podunk 4G USB stick I got from Digikey"
SanDisk Extreme USB 3.0 16GB
Kingston 4GB microSD with adaptor
DaneElec 2GB SD with cheapo USB card reader
Integral 8GB

Hoping I will not have to downgrade --- I will keep trying with other USB drives...

Sparky
