I would love to get a DG800 with 100MHz sine output,
but the hack seem to be closed now so i'll need to found
something other to get a 100MHz output...
Not many choice  available in low price tag. :'(

Amplitude accuracy of a hacked DG800 unit anyway is way beyond specs at frequencies above 70MHz. If we had the calibration instruction, we surely could convince a hacked unit to be accurate, but so far there's not even a firmware update (publicly) available -- not that it would be neccessary  ;). The recent 01.09.00.00 probably only had been released to close the hacking backdoors...

Anyway, I'm pretty sure the brillant code wizards attending here will find a way to get around that.  8)  :-+

I want to buy a quality Signal generator especillay for Sine and Multisine signals to test my sensors. I want to publish the data with the IEEE.
I'm skeptical between Siglent SDG2042X and Rigol DG952. which one has more cleaner signal?

If you need clean signal, in terms of S/N ratio, then Rigol DG800/900 series is not for you.  Also some jitter related issues have been reported.

I have another question.
I have realized an optimized Multisine signal to have a better Multisine, anyhow now I have 100 or 1000 different phases, if I want to generate this signal I should send these phases to a DDS core.
Can I send these phases to a Siglent signal generator? Which signal generator do you offer me?

Sorry guys (specially Ashdash). It was my fault.

Those who were expecting to upgrade newer FWs can retry:

https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg2631693/#msg2631693

The patch sector is corrected. I hope!

Nice work. I guess they need this functionality for production and they can't avoid it.

Although MSO5000 for example does not have this PROJ command, so they might be configuring it more manually. I tried inserting the key and didn't notice anything unusual there.

See private message.

Retried using new patch sector, but unfortunately no change in model.

Ready to assist.

Could possibly the serieal number of the device be involved in the "proper" machine identification?

My "almost better than new" DG811  ;) for instance has as S/N starting with DG8A20... but it's running the older firmware so the :PROJECT:MODE change worked.

I'm pretty sure that DG9xx instruments have serial numbers starting with DG9, so this could actually be used by the new firmware to identify if the device is legitimate to be changed into a DG900 series instrument. It's just a shot into the blue but since there appears to be a SCPI command :PROJECT:SN that assumingly permits to change/set the serial number, it may be worth to give it a try.

So, after a more detailed analysis, the verdict:

With the introduction of FW v00.01.09.00.00, Rigol replaced the :PROJ:MODE command with the :PROJ:MODF !!!!!!

MODE             MODE        :PROJect:MODE    (up to FW v00.01.08.00.01)
MODIF            MODF        :PROJect:MODIF    (from FW v00.01.09.00.00)

Nonetheless, they changed the validation sector of the MODE command but ended up disabling it altogether and inserting a new replacement.

The new replacement uses an ECC signature of the DG model string (ex. DG992) as a parameter. So, not super easy to change modes but still accomplishable.  ;)

BTW, a DG992 (ex-DG811) can be upgraded to v00.01.09.00.00 & beyond and retain all it's features including a S/N starting with DG8A...   :popcorn:

Ah, that is great news :-) I just received a new DG811 that I had ordered hoping to still find the old FW. But no, it already had FW v00.01.09.00.00. With a calibration date of
07.09.2019, BTW.

I will be eager to test the new method!

Don't give rigol any ideas  >:D.

So they sent you the new FW file? I assume no major changes other than what you have found already.

These equipments have 2 Option licenses:

DG800-ARB8M - ARB  - Memory Depth Upgrade Option
DG800-DCH   - DCH  - Single-dual CH Upgrade Option

In the latest FW version (1.09.xx), Rigol implemented a 3rd "license" (called 'TYPE') to validate Model conversion.

Maybe in the future Rigol will start selling this option and officially support upgrading Models via that scheme.

About to buy a new Function generator, torn between a DG800 series (Hacked if still possible) and a Siglent SDG 1032X
This thread has gone a bit quiet and can't find out much about the DG800/D900 series. The Siglent is about £50 more.
No sure what to go for!

I'd go with the SDG1032X or the older Rigol DG1022Z. The latter can be cracked to 60MHz still and outperforms both the Siglent and the newer Rigol units.

Telonic sell both. I think the DG1022Z is canned now though

Thanks, I hadn't heard of Telonic! Having a look on there now.

What's the best way to create and edit arbitrary waveforms ?

I tried Rigol Ultra station and it's only a trial and not working really well.

How did you figure out to crack the DG1022Z?

Of all the Rigol gear I bought thats the only one I haven't been able to find stuff for.

Right. That's how Ive done my scope, and psu. Nothing for the DG1022z though.

For those that frequently ask for a solution on the "model change" with the new FW v1.09: as I've hinted in the past, it's perfectly possible to continue to perform the "model change" with the new FW. Attached is the proof.

As I've said, Rigol now implements a license-type validation for the "model type" string. It uses ECDSA to verify the model string.

Maybe the best way for all is for someone release a binary patch to the v1.09 main app and place it in a .GEL. For now, i wont be releasing such solution although is perfectly doable by anyone that takes a look at the app. Or try the downgrade path...
