Decent modern Signal/waveform Generator here in early 2024

Are the fan noise an issue on the Siglents SDG2xxxX line, as it is a potent fellow with 1.2GSa/s, - way higher than both the SDG1000X (150MSsa) series and Rigols DG800 (125MSa) & 900 series (250MSa) as unsteady fan-noise, on Rigols latest sig gen are killing it for me & not what I had hoped & hard to love, not least after their "fanless" DG800/900 focus.
And likely anybody's guess when Siglent revamps these model segments.

Been watching a few reviews, and I can not even sense the fan on the SDG2042X Siglents, seems weirdly quiet even in videos where the user is sitting close to it...
Have noticed that many of the users on the forum purchased the SDG1032X or the bigger brother SDG2042x, makes sense, seems like a very solid build, from the teardowns and very beefy fundamentals in this price segment..

the SDG2042x still seems to go for around 600 euros, here in northern Europe, while abroad Amazon US it's a tad over 400 euro, been trying to see if the age late 2015/early 2016 signifies in any shortcomings, but then again its not like the wheel been reinvented since, many of the features are pretty fundamental, but still, some new adv features. do see daylight from time to time, and can meet a bottleneck in older hardware.
all the benefits are obvious., often more mature os, less bugs, a huge user back-catalog of info you can lean on and debate with etc..

Any comparable videos or articles, between Siglent SDG1000/2000 series and Rigol DG800/900, to give an insight into pros & cons..?
tautech:
SDG1000X has a different output stage than the earlier 2000X models which provides faster rise time than its bigger brother.
Apart from that, lower BW and 14 vs 16bit they are much the same.

Otherwise we need go to SDG6000X to get a faster edge, higher BW etc.

Just a note, make sure to call them 1000X and 2000X because there is older model 1000 without X suffix.

In a nutshell ?

SDG1000X has very good pulse creation specs. AWG memory is on smaller side (16k).
SDG2000X has better analog performance (sinewave distortion), better level specs, goes to 120 MHz. AWG memory is much longer.

For general purpose work 1000X is sufficient. For pulse work, it is better.
2000X has better stability and lower distortion. It is better for analog and AWG work.

Rigol is not doing that. After "upgrade", "liberated" BW is not properly leveled. There are topics here on that...
Funny enough, older Rigol DG1000Z was fully calibrated and adjusted so that one worked properly even after "upgrade".

Which Rigol model are you referring to?
the current lineup? the "not fully adjusted", meaning a lack of linearity in the liberated range?? how sever?

New DG800/900 series.. I mean, new, it has been few years now, since 2018...
Not lack of linearity, but output levels in "liberated" ranges drops off. By a lot..
There are numerous other problems too, software being buggy...
There is a hack topic and it is all there.

Shame. I like old DS1000Z, for what it is, and have kept it, despite having SDG6000X and SDG7000A available.

In meantime Rigol released new DGxxxPro series of AWG with yet another brand new OS and interface.
New system to again debug from the scratch, without ever committing enough resources to fully polish and debug old ones...
