The "ballpark" for the meaurement you have on screen is 3% of full range for the osciloscope (0.24v). To measure what you want accurately (2 decimal places) you need a measuring device with a .02% DC accuracy or better. Does the signal generator pass when measured agains the 34401? If so, there's no issue. Osciloscopes in general only give a rough reading on vertical, think about, most have 8 bit adc, some 10, that's not enough for what you're asking.
-
So it's about scope vertical resolution then.
After turning "high res" ON 5Vpp measure shrunk down from 5.22V to 5.1V on DS1102z-e.
No major changes for Vrms 1.76 instead of 1.77. Btw 34401 is showing 1.788 (so technically its +0.0005V outside specified threshold). However my DMM is from mid 90-es and God knows when last calibration was done. Close enough for my use cases. Thanks guys for clearing that up for me.
edit: I just tested with other "low cost" 50 Ω terminators and it affects Vrms value. Figures above are with "average aliexpress" 50.9 Ω terminator. There you go another variable to count in, so lesions learned... -
After upgrading dg811 to dg992, can we continue to upgrade the subsequent official version in the future? Does Rigo have the ability to detect the difference between the system and the hardware during the upgrade process, so as to refuse to upgrade or even lock the machine?

Edit #1
Nevermind, I managed to find it.
Steps:
Go to: https://tw.rigolna.com/firmware/
Copy the Link for DG800 / DG900 FW
Paste and edit link, change /ct61_0/ to /ct65_0/ and you should get a package named "DG2_FW.zip"
Edit #2
FW 2.06.01 installed fine without hick-ups, my device kept its "Rigloled" state.
First impressions: There have been a lot of UI changes. Can not decide if for the better or for worse.
-
Upgrade done. All good until now.

You can download the firmware 02.06 from the rigol Chinese website

I guess that's an interesting change: "- Calculation of modified carrier amplitude"
I checked AM carrier behviour with the updated firmware and found the following, reasonable approach:
When enabling AM on a sine carrier, the carrier gets reduced by 6dB regardless of the selected modulation depth. This means, at a modulation depth of 100%, the entered signal level is valid for the overall, modulated output signal. Reduction of the modulation depth only reduces the level of the side bands, the carrier stays at a constant level. Though this means that the selected output level isn't correct for modulation depth less than 100%, I guess both "parties" can live with this approach -- the output amplitude won't exceed the dialed-in level / amplitude while the carrier stays constant when checking RF gear. I'ld say, "well done, Rigol".
The other changes (especially to the UI) appear to have made the interface a little more consistent to use, but I've got to admit I didn't do much tinkering with it , a few details have been changed that the user has to get accomodated with, but I think these are no-brainers.

... amplitude while the carrier stays constant when checking RF gear. I'ld say, "well done, Rigol".
Yep. carrier level must not change when change modulation depth. When it is solved by this -6dB solution it meet this main principle. -6dB drop is ok compromise so noobs do not burn they circuits with peak level if "accidentally" turn AM on with high mod depth.
"well done, Rigol"

Can we still crack the firmware after upgrading to version 2.06? Or can we go back from 2.06 to 2.04?
-
Just want to thank the many people involved in the hack
-
After upgrade to firmware 2.06.01, the Max. Output Amplitude also have changed from 10Vpp to 20Vpp.
-
I`ve read so many posts, but actually what ist the right procedure to now UPGRADE HACK a newly purchased (as of MAY 2021) DG811 to DG992?
PC Connection, Magick Stick, Linux to format it???, etc. isnt there an easier way?
Sorry if it has already mentioned but I just want to be sure before purchasing the DG811, that its possible to hack, btw. I have a Mac and PC running Windows 10 so no linux!
Thanks in advance!
-
After upgrade to firmware 2.06.01, the Max. Output Amplitude also have changed from 10Vpp to 20Vpp.
Probably the output reference impedance had been changed from 50R to High-Z. The actualy output amplitude is hardware limited and won't be changed by firmware. +-10V is what the AWG is capable of High-Z. -
I have a Mac and PC running Windows 10 so no linux!
there is no need to install linux natively on any of your machines. But there is no escaping from linux tools unfortunately. (edit: Wrong. Yes there is a way to avoid linux tools, see next post)
You have 3 options there:
1) Use the listed puppy Linux ISO image to boot from. Your windows installation will remain intact (unless you tell it do install on your PC).
2) Cannot confirm completely, but I think that I did it through MacOS with brew. Formatted through normal Mac tools, and then did the dd command from MacOS command line.
3) Install linux in a VM on your Mac or PC (under VirtualBox, but better under VMWare). Ubuntu for example is really easy to use. And it will open up a whole lot of opportunities for other projects. You can then simply pass the USB disk on to the VM, and follow the procedure.
Just in case you might be tempted, do not use WSL for this: https://docs.microsoft.com/en-us/windows/wsl/ (Stay on WSL, do not install WSL2, as the networking for that is broken). Although it is a fairly easy way to use linux command line tools without resorting to Virtual Machines, natively mounting USB drives is messy with that, and the commands used for the hack will very likely not work.
-
Just for creating the "magic thumbdrive", you don't need to have a Linux machine. I did all the patching without a PC running Linux at hand. Look here how to create the thumbdrive on a windows machine (or maybe also on a MAC -- provided a disk editor is available).
-
There are raw disk access utils for every OS other than Linux. The risk is if the user knows how to use them and/or replicate the instructions given for Linux.
But this is a forum for engineers, right? -
Thanks for the hints and tips, maybe I will order one and try to unlock it :-)
So these steps should be the current ones???As I have just successfully upgraded my DG812 to DG992 I would like to post yet another summary of the required steps.
0. Note your DG's serial number if you care.
1. If you have software version higher than 00.01.08.xx.xx you need to downgrade to version 1.08 using specially modified GEL file to allow downgrade (as described by evgbog here: https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg3017342/#msg3017342).
My contribution is that I've prepared modified GEL file, available here:
https://drive.google.com/file/d/16nC-uJ12MXilJElv4Eukvt1IW4RzGdb7/view?usp=sharing
Put the file on USB stick, plug it into your DG and accept "update" when popup shows. WARNING! This "upgrade" will reset your SN to DG80000000001 but convert your unit into DG992 immediately. This is the effect of the downgrade itself - the firmware is official Rigol firmware. The modification only changes the boot script to allow downgrade.
As a side note, I don't see a point in using hex editor in evgbog method of preparing the GEL. Those GELs are tar files as mentioned by tv84. I prepared the file by simply untaring it, decrypting fw4uboot.sh, modifying it, encrypting it back (you need to maintain file size) and finally TARing everything back into GEL file using 7zip.
2. Prepare a "magic" USB stick. Format USB stick as FAT32 (stick MUST BE BIGGER than 1GB). Open it in HxD editor as LOGICAL DISK (not physical disk - I did that mistake) Tools->Open Disk (uncheck "open as readonly"). Jump to sector 2000000 (sector field is at the top right corner). Enter value manually or use "Paste write" in edit menu (Ctrl+B). Magic value: 0B0A3B2E5F4CECBE
3. Insert the magic stick into DG (make sure it is recognized and USB icon is shown) and connect the instrument with the computer (using USB A-B cable and downloading Rigol's bloatware UltraSigma is the easiest way). Open SCPI command panel, check communication by issuing *IDN? command (use Send & Read). Send command :PROJ:SN DGxxxxxxxxxx with your correct SN number noted in step 0 (use Send command, DO NOT USE Send & Read). Verify if it worked by sending another *IDN? command - it should report back with correct serial number. Now send command :PROJ:MODE DG992. You can disconnect the instrument from PC and remove USB stick.
4. Edit: This step is only needed if your purchase version was higher than v1.08 and you did step 1 Download tv84's "Finish_Upgrade_2.04.zip" from this post: https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg3119264/#msg3119264
Put this GEL file on USB stick, plug into DG and confirm update when popup shows.
5. Download official 2.04 firmware from Rigol: https://int.rigol.com/Public/Uploads/uploadfile/files/ftp/DG/软固件/SardineII(ARM)Update-v00.02.04.00.00.rar
No logging in required
Put GEL file on USB stick (delete the previous one), upgrade DG and enjoy
Serial number should be kept and model should be DG992.

Seems to me that blue is the new color they use, or maybe only for some series, no idea. Mine also has a blue logo.
Was mentioned here: https://www.eevblog.com/forum/testgear/rigol-ds1202z-e-entry-level-scope-(200mhz-2-channel)/msg2737562/#msg2737562
See also this for example: https://www.rigolna.com/images/products/MSO5000-E.jpg, or https://www.rigolna.com/vna/ (the RSA3000N). Some are blue, some not.

Mmmhhh... - I don't get it?!
They change it from yellow to blue in printing, but keep it yellow in the display, which is much more easier to change - very strange policy...
But you are right: it seems to be the new standard.

G'day.
One more peculiarity I found out about firmware 02.05: Rigol has changed the SSH encryption key vs. F/W 02.04, so in order to use @rea's login approach, it's necessary to downgrade the firmware to at least 02.04.
Not sure what is the SSH encryption key you mention: the contents of /root/.ssh/ aren't encrypted by anything. And I had just checked that http://codelabs.ru/firmware/rigol/dg8xx-9xx/2.05.00-enable-ssh/ works on 2.06.01. -

Did you succeed?
I am afraid of getting confused totally when going through this whole tread. Planned to buy an FY6900, found Uni-T's 692 suitable for me (but where to buy from Germany?), found the PSG9080 and put it on the wishlist until I read the manual and reviews for the DG811. THIS is it. -
Hi,
With or without termination? -
After upgrade to firmware 2.06.01, the Max. Output Amplitude also have changed from 10Vpp to 20Vpp.
