Sure. If you will use it as-is. I know of few to none private users or small businesses who won't consider hacking. Sorry, but IMO your point is ridiculous.

how far can you hack that 125MSa/s device? i dont follow the hack thread sorry. i assume to the max 62.5MHz? do you call 2 points per cycle distortion free pro/business grade? not mentioning the other fun stuffs such as freq resolution when you go near that limit... enlighten me please.
TurboTom:
The DG811 can be hacked to full DG992 performance (except for amplitude accuracy that drops by about 2dB between 70 and 100MHz -- unless we figure out how it's supposed to be calibrated). The hardware of the models is identical as a common service manual in chinese language, that's surfaced somewhere, proved (same P/N of main PCB). The information that the DG800 series has only 125MSa/s of scan rate is wrong and may have been published in a very early design phase by Rigol. All these units run at 250MSa/s.
Price-wise, I only compared the PSG9080 with the DG811 since in my part of the woods, provided I'ld had to pay full import duties and VAT for the JunTek unit, they would be on par (give or take ten eurobucks). Construction-wise, there is no comparison. Reliability and safety-wise, I trust Rigol's instrument 100% while the PSG9080 could, well, use some improvement...
I agree with you that as a hobbyist's low-cost AWG, the UTG962 appears to be a decent choice.

Really? In Europe, several T/M gear distributors have stock available. Btw, once again, the 125MSa/s specified on the linked page is wrong. All these units sample at 250MSa/s.
Or did you mean to refer to the UTG962 which really appears to be difficult to find meanwhile?

batronix... is euro currency, and its not very friendly to us... well i stand corrected... dg811 also sold in aliexpress $279... https://de.aliexpress.com/item/10000098463394.html?spm=a2g0o.productlist.0.0.c6a635c7RYMVym&algo_pvid=b308c759-b632-44d5-838e-bb0bbecadc8d&algo_expid=b308c759-b632-44d5-838e-bb0bbecadc8d-1&btsid=0bb0624016012866100348760ec1be&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
i was not aware it can be hacked to 100MHz so i stand corrected, but still $200+ is something for me ;) cheers.
