Now, how to make Bode with the DHO804+DG800
VESA mount and external USB power. Very bench space friendly, compared to the "shoeboxes" we've been accustomed to for signal generators, counters, bench DMMs etc.
One thing I personally interested is the Amplitude: Up to 20Vpp at high impedence or 10Vpp at 50 ohm

Who wants a lab instrument that looks like a toy?
I always ask myself what is missing when something is very small.
Nice DHO900 styling -- "collect 'em all!"
But I will never understand what the Rigol designers were smoking when they introduced those circular number keys. How am I expected to enter numbers there?! What's wrong with the rectangular arrangement used on calculators or phones?! Who wants a lab instrument that looks like a toy? I am flabbergasted that they kept this absurd button arrangement on the new series.
Now on to the real question.. is the hardware of the DG800pro and DG900pro going to be the same?
it works, its not as good as a number pad but it is usable. ...It does seem a wilder of a choice. Where is the V button? Its just M/G/k/hz. So its easy to type in frequency but not easy to enter a voltage.
It should based on the RK3399 + ZYNQ + Rigol's own ASIC and running Andriod just like DHO scopes.
Is anyone able to access the data sheets for these instruments from the international site (rigol.com)?
THD<0.1%("Audio Range")....Not bad.
Unfortunately the jitter specification is not just bad, it is laughably bad. On par with the UNI-T UTG932

How do Siglent's compare ?
And I found this Rigol patent from The China Patent Office
The patent name is "DMM", so there might be another DHO-liked product coming soon!
DM858: 5.5 digits, 125 reads/s, 0.03% precision. $499
DM858E: 5.5 digits, 80 reads/s, 0.06% precision. $274
Very bench space friendly, compared to the "shoeboxes" we've been accustomed to for signal generators, counters, bench DMMs etc.
They made it! Just today Rigol drops the DM858 and DM858E
Very bench space friendly, compared to the "shoeboxes" we've been accustomed to for signal generators, counters, bench DMMs etc.OTOH a dull shoeboxes can be stacked resulting in real space saving.
it probaly still running Andriod, I personally think this isnt the best choice for an DMM... I dont want to wait like 1-min before I can actually start mesuring something
if you were to be - is there any chance that you might request a trial unit from Rigol? If only for an unboxing and a quick poke around its capabilities?
btw the product will start shipping at the end of December.
First review of DM858:
https://youtu.be/u8b5gk9B6sY?si=snLz2PGAvtlzi1gi
Interesting that the DM858E is nerfed on the current to 3.15A from 10A. Wonder if this is a fuse change. Reading storage is nerfed, likely a key change. Haven't been able to make out how far the frequency function works up to in the manual.
Tried some of the regional script standards in Notepad, but none of them would play along.?
How do you read these Chinese release notes?

But a bit suspicious that I can only find it on an Italian site. Hopeful it will be available in english soon as well.
Now the big question. Is any of this upgradeable (hackable) ?
You can get these models from many European sources.
Eleshop, Batterfly etc. etc been for sale for some weeks now. https://www.batterfly.com/shop/en/blog-posts/rigol-dm800-dg800pro-dg900pro-introduction
Also all the manuals, and datasheets are in English, so I don't have to rely on bot-translated CN variants from Nov.

Eleshop says "Expected on 15 Mar" on some models and "lead time 10 days" on others, so not quite there yet but really soon?
Still waiting to hear if we can unlock them
Can you tell me if it is possible to load my own waveform?
I couldn't find it in the user manual.
...
[...] when I'm reading the specification, I feel like it's using an off the shelf handheld multimeter chipset.
I'm a bit surprised there isn't more talk about these, especially after the success of the 800 series scopes.
I would not have used the round numpad, I prefer the touch screen.

I misunderstood ebastler's post.
He wrote for AWG and I meant for DMM.
But I would also use the touch screen on the AWG. I'm already good with the stylus.
Are you on the firmware from 12-1-2024
Are there any development hence hacking/liberating it
I have a dg821pro and I managed to turn it into a dg922pro with all the additional options
Therefore, you can safely buy simple models

I'm surprised the DG800Pro series contains the hardware for the higher sample rates of the DG900Pro series.
The teardown ( https://www.eevblog.com/forum/testgear/rigol-new-dg822pro-teardown ) shows a TI DAC38J82, which is a 2.5GSPS dual channel DAC (1.25GSPS per channel).
Strangely, TI has a pin-compatible 1.6GSPS part in the same lineup at almost half the price: DAC37J82. This lower spec part would make more sense in the DG800 series, which tops out a 625 MSPS/channel, or 1.25GSPS combined.
I wouldn't be surprised if later DG800Pro builds started coming with the cheaper, lower sample rate variant DAC. Seems like Rigol is leaving money on the table by putting the faster DAC in the slower model when a cheaper variant is available.
Maybe it does. These lower specced parts are sometimes the same die, that doesn't meet the specifications, but you can unlock the extra speed or bits if you use the same code.
Any way to validate if the DG821PRO are able to obtain the full sample rate of the DG900PRO series.
Which on paper can muster 1.25GSa/s - 16bits - 200MHz -32Mpts.
It's a pity that Rigol didn't use the opportunity when designing the DG XXX Pro series to eliminate the shortcoming of CH2 to be disabled whenever the frequency counter function is active (as the manual states) -- this "feature" was also present on the "non-Pro" models. Except for the higher frequency capabilities, the bigger screen and the "funny" fonts, this new model appears to provide little (technical) improvements over the older specimen...
Whatsoever, if the "uphack" is and stays possible, the entry level "Pro" model probably isn't a bad choice, provided Rigol won't "disimprove" their firmware too much...
I'ld just expect that when buying a state-of-the-art 2-channel AWG with an additional frequency counter function, to be able to use the two AWG channels while the counter is activated. What I don't expect is that one of the AWG channels drops out of operation when I enable the frequency counter.

I've been just putting this issue up since I wanted to point out a missed opportunity by Rigol (among many others...). I.e. first deliver a "finished" firmware for the "non-Pro" versions . If I need a decent frequency counter, I use one of my hp 53310A MDAs. None of the AWG-integrated counters stands a chance against these "dinosaurs"!

Looks good csushi17 thanks for sharing..
You took the plunge on both DG912PRO & DM858..?
Whats your impression sofar?
Took a web-look at the different chip-markings your posted (as different) but my web-kungfu is weak sauce, so nothing popped up-
A compare DHO814 & DG822PRO cirquit board.They seem to be using the same screws.Your sharp
its the same board template.. so a lot of rehash of the secondary components/sockets DHO800/900, DG800/900PRO, DM858/E.
Quite populated these signal gens and not much seems to be unpopulated (if any) but on paper, the DG800PRO allows only up to 8M (optional) and 2M native while DG900PRO its 32M optional and 16M native..
A board picture of the DG900 would be helpful to see if any of the chip differs.

However, now that it turned out that the 800pro and 900pro are the same inside, I'm a little saddened, but I'm also happy at the same time.
So maybe if someone buys the cheaper version and hacks it, they will be fine with it.

It's clearly done by two different teams, one using silkscreen the other doesn't. Somehow the oscilloscope doesn't have any electrolytic capacitors as well.
....
+Its fan is horrible.
I actually wonder what's below the metal shield. It seems small, Rigol doesn't do DMM chipsets so it will be someone else's chip there.
Thanks for posting, now I'm seriously considering getting a DG821Pro instead of the SDG2042X (to be hacked into SDG2122X). But the boot time seems to be long enough to be annoying.
I wonder where the operating system is stored. What's under that secondary board that's installed in what looks similar to a laptop memory module slot?
But one thing that would really put me off getting Rigol's "Pro" series AWG is the use of a hybrid module as the channel output amps. They may be designed pretty well and beefy but there's always a hatch that "Murphy" slips through and the pamp may be damaged by mishaps...
I would rather treat it as a consumer electronic product as it cost a fraction of an iPhone. If I blown up the front end by reverse power, then I buy a new one.
Also considering how fast the digital electronics are advancing today, hopefully by that time I can get one with even better specs. I was dreaming for but couldn't afford a second-hand Agilent 33250A when I was in high school, but today, meh...
Now the question is should I get a DG800Pro for hacking or a SDG2000X. I have the equipment to calibrate the frequency response if necessary. SDG2000X is a bit old now, I don't know if Siglent is going to release a newer model.
last news for DG821pro
device can't produce frq above 200mhz ;(
but can do modulation (am and fm modulation) up to 200mhz
Would you willing to share how you do this? Or just some tips?

becouse activations not fully documented now/not tested, you can send me config files from /rigol/data folder to fix configuration
i soon will make new thread with info about activation and calibration dg800pro/900pro

- The fan on this thing is horrific as mentioned, it starts off really slow for a few minutes (5V), then ramps way up (13V). 13V is even overdriving it as it is a 12V rated fan. Whoever designed that fan/heatsink should be slapped. Probably some intern. 70 or 80mm fan will have to go in.
What is the power consumption level btw? I mean whole device, not just the fan -- I wonder if there's a real reason to run the fan at 13V. Does it draw more than the scope (35W IIRC)?
What is the SSH password? The usual root:Rigol001/Rigol201 etc doesn't work.

- The font is not great, but nowhere near as bad as the DP900 font. Still regular font would be better, without the graininess.

I thought it couldn't get worse that the DHO800/DHO900's fan. I was wrong, it can! It is already terrible at 8V, scary to imagine what it is like at 13V. And having variable speed on it doesn't make it any better.
I suggest checking the three DHO[8,9]00 threads (hacking, unboxing/teardown, and there was one more that I can't recall now): search by "fan" in them. There was a long discussion, and also a few solutions to the problem were described/demonstrated: from installing an external 120mm fan to lowering the speed of the stock fan to get an acceptable noise level while, as was claimed in that particular case, keeping the temperature at a reasonable level.
What model do you have?

I'm on the same boat but without calibration equipment. I would go for the Siglent one if it wasn't for the web control in the DG800/900 pro series which comes in handy for didactic purposes.
If recording the screen was not in consideration for me, I think I would be inclined to go with the Siglent
