content: Hi I am looking for a Dual channel AWG. My main concerns are desk space, easy user interface, P-P voltage, and lack of noise.I am stuck between the Siglent SDG1022X Plus and the Rigol DG822 Pro.Background: I own 1 Rigol product, a DHO804 Oscilliscope in the same package. I do not like the noise the fan produces. I have a few caveats with the design like the lack of an effective visual reference for ground and difficulty to find DC voltages greater than 10V, with an ability to get "lost" looking for DC. That just seem like poor engineering from Rigol to me. I like the touchscreen and I find the user interface very easy to work with.I want to purchase the DG822 Pro because of the user interface and touchscreen. I believe it comes out of the box with a switch mode power supply so no cutting the ground off a 3 prong cable. The main thing I am concerned about is the fan noise and desk space increase. I dread turning on my DHO804 because of the background noise of the fan. I am not sure if the DG822 Pro is just as loud.I want to purchase the SDG1022X Plus because of my caveats with Rigol. I get the feeling Siglent will overengineer where Rigol has been questionable with some aspects with their oscilloscope like like getting "Lost" looking for DC. It will be quite which is the biggest advantage for me by far. The SDG1022X Plus should have better signal quality I am only concerned about "good enough".I am not sure on the custom Arbitrary waveform software. It seems like Rigol may take the edge for being intuitive to learn for new users. Which is mostly what I am concerned about. TrueArb seems better in general but potentially harder to learn which I am not stoked on.It would be amazing if someone responded who has owned both. I would be happy with some insight from anyone who has knowledge on one of these products.

content: I've owned neither, and I hate Rigol (based on my own experience with them), so take my opinion for what you will.I currently have an SDG2122X, and it will be replaced with an SDG6052X. The Siglent SDG AWG series are all similar, and all good.The SDG1022X Plus is nice, has a remote web control console, and can beimproved. If you ever get a better oscilloscope, like one that says Siglent on it, the Siglent AWGs can all be used for Siglent's excellent Bode plot. Rigol bode plot is mediocre, as is their FFT (according to people that own Rigol stuff).Thanks,Josh

content: All i can say is, the SDG1022X Plus is not silent! It is in fact the loudest thing on my desk right now. Defpom mentions this in one of his videos:Start at 5:26

content: They are very different signal generators.Look at their datasheet and compare their differences and what matters to you..The Rigol is pretty loud on its fan, it seems to be the same fan as in their DHOxxx scopes, soif fannoise is paramount to you, then take a look at fx passive units..- even the older line DGxxx without PRO was passive as I recall...ON DG822PRO its a temp based fan, so in theory its not always on, but it will start up pretty fast and cycle, as these DGxxxPRO seem to have a weirdly big amount of heat they need to dissipate from a 35-watt device..Do you plan on upgrading either of these to a higher revision? As I reckon, both of them can be liberated to higher revisions.Only got the DG821PRO (lowest base model), which I got back in late 2023 on a speculative approach, that it hardware-wise, was the same as more expensive units in the series. -Saw it as a cheap way to get some decent specs (16bits, 1.25GSas, 200MHz 32M).. Was back then a tad under 250€ at the singles day 2023 sale, incl. 25% EUVAT, and so far it's been a pleasant companion,- but its not silent by any stretch, it has a relatively annoying temp-based fan, but I do apreciate the big touchscreen on a modern siggen, makes it easier to adjust variables.it's overall quite capable..at least up to around 200MHz.
