How can I activate the advanced properties of Rigol Ultra Station ? Thanks for any help from now
(Is there a solution on "https://www.gotroot.ca/rigol/"?)

Getting started with LXI LAN wonderful world in my little home lab corner. My current Siglent DMM and Rigol scope have LXI support.
It looks that I can add USB-LAN adapter to my "upgraded" DG812 unit. Will it be LXI protocol compatible? Manual does not mention keyword LXI anywhere...

Yes it is.

Thanks to you, I have a DG811+, with FW 2.06. Great job by the people making this possible.

I have noticed errors in the FW:
1) As some noticed, most of math arb waveforms are missing. But also some engineering waveforms: all from TV (voice, surge, radar, etc).
2) It does not connect via USB to my DS1102Z-E, as it should, in order to transfer the waveform seen by the DSO to the SG. Both devices detect the USB connection, but the DSO does not get into slave mode and the corresponding menu in the SG does not appear.

Should I downgrade to 2.04, or does it have some issues?

[SpacedCowboy]

So I bought a DG812 off Ebay last week, and it came with the v00.01.08.00.01 firmware (I guess I got lucky and following @tv84's instructions in post 146 has turned it into a DG992.

I used Windows to format the flash drive to FAT32, but didn't tell it to do anything special, then ran dd on a linux box, then did the SCPI command using UltraSigma. Worked wonderfully, thank you tv84

The only wrinkle was that I was trying to use a network cable connection for the SCPI, and the DDG812++ only has 1 USB host port, and it doesn't seem to like using a USB hub to plug in both the USB<->Ethernet and the USB flash drive at the same time. So I had to string a *very* long USB cable between the PC and the DDG.

The direct USB connection between the DG800++ and the PC may have an additional disadvantage: Both ports are ground-referenced. On the AWG, the ground is referenced to PE and on (stationary) PCs (usually) as well, so you may end up with a ground loop, especially if the wall outlets that the two devices are plugged in, are "electrically" remote from each other. This may or may not cause a problem with your measurement setup, but if you should encounter noise or hum issues, you should at least keep that in mind and try cutting the USB link to identify the problem.

Now that it’s “upgraded”, I’m free to just use the network connection, and since I’d wired that in neatly, that’s the plan, but I’ll bear that in mind if it happens that I need to use the USB connection in future.

Both PC and DG800++ are ~10’ away from the sub-panel in the shed, but they’re on opposite sides of the shed. The PC isn’t very accessible (it sits 6’ up on a shelf with wiring coming down to a KVM, I’m generally using the Mac Studio) and the only USB cable I had that was longer than 6’ was a 30’ one that I’d previously used to hook up an SDR-based radio-telescope)…

1.)The same problem as mine.
Perhaps could the problem be solved by copying the original arb files from an DG811 and send them back to the patched system?
Perhaps someone could have these arb files in original and could post it?

1.)
All arb waveforms are there, but without the pics. Only Push the knob down into the next free and empty Space and the next function appears with icon.
But why the pics aren‘t shown. I don‘t know.
There is somewhere  a bug. But where?

[at2]

I hope no one minds me summing up the steps one more time for clarity. It's other peoples hard work we have this, not mine.

It's misleading such a detailed procedure to end up without a valid S/N. You missed the steps to keep the S/N!

Hello TV84,

after doing the upgrade steps with success  there are some arb files missing in the DG992.
They are present but not shown as icon like it should.
Is this a known problem after this patch or not likely ?

 

[wmattias]

Just wanted to report that I recently purchased and "upgraded" a DG811 that came with Firmware 00.02.06.00.01.
The main selling point for me was Fanless design, otherwise I would likely have gone with the Siglent.
Overall I like the usability of the DG800, UI is fast, responsive and easy to use.

Upgrade Path

I followed Post #867 and Post #809.

USB Drive & Ethernet Dongle Compatibility

I had some issues with getting the DG811 to recognize my USB drive, but a tried a few different ones and one of them worked.

I also ordered a few USB Ethernet connectors, some didn't work but this one did:
"Rankie USB Network Adapter, USB 3.0 to RJ45 Gigabit, Black" (ASIN B010SEARPU)
https://www.amazon.se/-/en/dp/B010SEARPU/ref=sr_1_1?crid=1XHI89LOGVOCI&keywords=Rankie+USB+N%C3%A4tverksadapter%2C+USB+3%2C0+till+RJ45+Gigabit%2C+Svart&qid=1656509153&rnid=20693452031&s=electronics&sprefix=rankie+usb+network+adapter+usb+3.0+to+rj45+gigabit+black+%2Caps%2C89&sr=1-1

Missing Waveforms

I can also confirm the some of Waveforms are missing. No icon shows up, but they are there. When i scroll no icon appears either, but after having pushed on a black area the waveform will be selected and subsequently visible in the "Arb/Common" shortcuts menu.

The following are missing (I didn't list all, just first and last):
Engineering: Voice, Surge, Radar, ..., PWM
Medical: ECG7, ..., Tens3
Math: ErfInv, ..., TukWin

Measurements

There's an amplitude drop when approaching 100 MHz.
Can't tell if it's my Oscilloscope, Test Setup, or the DG811.
Providing my testing results here (see attached image).
Tests done using DG811, SDS2104X Plus (upgraded to 500 MHz 2354X Plus), and a Caltest CT2417 50 cm BNC Cable.

Yep, reported about on the previous page in this thread:

The 9xx model may undergo a lengthier calibration procedure -- the 8xx variey isn't calibrated all the way up to 100MHz and apparently also has fewer calibration points in the low frequency region. Nevertheless, the latter perform quite nicely up to ~70MHz and show some 1.5...2dB of level drop up to 100MHz which isn't a show stopper for most hobby applications.

This will certainly be a show stopper if you need accurate results from the Bode plot feature in your X-Plus DSO anywhere near its max capability of 120 MHz.

About that scope, straight from the factory the 100 MHz model has a -3dB BW point of ~185 MHz.

Make sure you are not using the 10 bit mode with your SDS scope. We just did a quick test since everything was already setup with both SDS2000X+ scopes (2 and 4 channel), and used a quality cable. Our source was a SDG2042X AWG, and the reading was just ~0.05dBV down on 2 channel and 0dB at 120MHz on 4 channel. Then we used a SDG6022X AWG and 2 channel was down ~2.8dBV and 4 channel ~1dBV at 500MHz. Awhile back one of the scopes measured ~600MHz -3dBV using a RF source, probably 4 channel but can't remember.

Anyway, hope you get this sorted out.

Best,

[wmattias]

@tautech : Yeah, agree it's extremely unlikely it's the scope. Like you said, 99.9% it's the DGxxx calibration that is needed (just like you mentioned other users reported). Love that scope btw.

@mawyatt : Ha ha, yeah initially I actually had the 10-bit mode on. Was a bit surprised by the (even sharper) falloff (measured 589 mVpp @ 100 MHz) - then I remembered the 10-bit mode has a cutoff @ 100 MHz. So yeah, scope and cable should be fine. The high frequency drop is similar to what other users who upgrade the DG8xx reported (i.e. calibration procedure needed).

[suspension]

Hi everyone, I am also thinking of buying a DG8xx model and use this hack to upgrade to DG9xx model. Could I please know if this hack still works and latest tutorial/instructions on doing the same? Also great if I can know what the major limitations are in this approach.

Thanks
Sus

I have tried two different USB LAN adapters and neither has worked.  Does anyone have a link to one that does work?

Hi folks!

Anyone has a fix from Rigol for missing waveform icons in Engineering, Medical and Math menus in FW 02.06.00.01 ? The latter (Math) is most annoying

[suspension]

Just wanted to confirm that the upgrade process documented in the post #493 worked well with my DG811 without any issues. Device had firmware version 2.06 originally. After this process the device has 2.04 version firmware. The post #809 mentions that the device can be upgraded to 2.06 although I was not able to find such a firmware version for series 900 in Rigol's website.

Tested 100MHz sinewave (2v pp) and works well although full swing is around 620mv. See my pics.

Thanks everyone who have contributed to this.

What type of cable are you using to connect the signal generator to the scope?

[suspension]

 
I didn't have one so used the scope probe and completely forgot that I used a scope probe!

HOW TO CHANGE RIGOL DG800/DG900 MODELS

1. Get a blank formatted USB disk (capacity >= 1GB)

2. Write signature in the disk with the following command (in linux):

        sudo dd if=DG800_sardinha.bin of=/dev/sda1 bs=512 seek=2000000

3. With special USB disk inserted, send the SCPI command (for example) to change model to DG992:

        :PROJ:MODE DG992

Possible model types (as seen in the first 4 bytes of sd.xx configuration file):
00 - DG811
01 - DG821
02 - DG831
03 - DG812
04 - DG822
05 - DG832
06 - DG952
07 - DG972
08 - DG992

ATTENTION: Use a blank disk and be sure it's mounted as /dev/sda1. Don't blame me if you do things wrong!!

(I included some pics kindly sent by a voluntary member)

Hi @tv84 and folks,

Nice job Sir!! But I think I've read this post too late. I have purchased the DG2052 and I'm wondering If this hack might also apply to this model since they share almost the same layout with DG800/DG900.

Thank you!
