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
