content: I bought a SDG6022X. It's pretty good. Does the job. Hackable. Runs a bit hot, though. Hopefully it doesn't bake itself in warranty + 1 year. Spurious performance is unexpectedly good. Max amplitude falls off quicker than I might have hoped, though. Decent bit of kit, I guess.

content: Yes, the hardware is quite decent and capable but the firmware leaves still a lot to be desired. The whole U/I deserves a revision with some focus on the touch screen. Basically, it's the same U/I of the smaller AWGs of the family, the SDG1000X and SDG2000X. I think, the 2000X is the "sweet spot", considering the performance for money you get. Price- and spec-wise, the SDG6000X clearly plays in the professional field but doesn't match regarding reliability and dependability. It's a shame Siglent takes so long to fix the reported bugs...

content: Agreed. My previous arb was a SDG2042X, which I'd agree was the value sweet spot, but in any case when I bought the SDG6022X my expectations were well-calibrated. I needed a few extra MHz, PRBS with controllable edges, and no migration fuss. That's exactly what I got. The limited I/Q generation software, limited modulation bandwidth, and cramped GUI leave no doubt that it's an overextension of the low-end platform, but hackability makes up for that. Between the tradeoffs and long updates it clearly serves a small niche, but I'm also in that niche. I made this thread as a joke but it's also exactly how I feel. Shrug.

content: Yeah. The specs in the datasheet fall off a bit quicker than I might have hoped, just like the actual performance. I don't actually need the amplitude, though, so it's all a big shrug. I feel pretty medium about it.

content: Quote from: tv84 on October 19, 2020, 09:16:52 pmThat is better than feeling bad. I bought 2 pieces of Siglent gear and felt bad about both. Actually I'm happy I got rid of my last piece of Siglent gear a couple of days ago. Good riddance.

content: Honestly though, I like my Siglent scope. For quick check of this and that, can't beat that AUTO button that most of the times, it's spot on. A mind reader button...
