Cool.  Thanks.

Which of the two do you use yourself, or even both?
I am also a friend of as cheap as possible and also think that some manufacturers are simply overpriced.
But if something costs almost half as much but is supposed to be just as good, as you said, then I have "natural doubts".

MathWizard:
I have the SDG2042X, and I've had no problems with it. 1st ever real sig. gen, and it's easy to use.

Sometimes I would like it if when changing frequency on the 1M digit, it would go down to 900kHz, not 0Hz, when you turn the knob. But sometimes that's ok.

The 2042X is great for the money. I have my eye on the SDG6022X, that will suit me perfect, and the next range, the RF gen's 7000series, are way way more expensive, so I'll be delighted if I can hack it to 500MHz.

Thanks for the printscreen with all the 3 outputs.  Looks like there is a small reflection coming back, the step after the 1st division at each edge, most visible on the Rigol trace.

For that Rigol DG4000 series, there are 3-4 models with same hardware and software limited to 60...200MHz.  Just so you know, any DG4000 model can be unlocked to 200MHz (sinusoidal) and turned into a DG4202.

14bits DACs, 2 output channels, it's nice to have signal and sync out BNCs for each output, external trigger, and has a 200MHz counter/frequency meter, too, with a BNC on the back.  Can generate up to +/-10Vpp in a 50ohms load (at lower frequencies, at 200MHz only 1Vpp), and has a DC mode, too, which makes it a dual channel +/-20V adjustable voltage source with a 50ohms internal resistance, so it can power small current loads as if it were a power supply.  :)

Has 10MHz in/out, too, to drive the internal clock synchronized with other instruments.  Worked OK so far, though it costs 2-3 times the 300 euro proposed budget.

The more expensive Siglent SDG1000 doesn't bring much extra to the table in this market segment so value for money is low.

That of course depends on what your application is, for your applications the Uni-T suffices thats OK, others and I obviously have different preferences, that's how life is.  ;)

That is the kicker, there is next to nothing the SDG1000 is actually better at compared to the UTG932 / UTG962. And the UTG932 / UTG962 have better specs compared to the SDG1000 where it comes to jitter for example.

While I think that UTG962 is good value for money, and certainly much better than what you would expect for the price, let's not get carried away.
SDG1000X is a piece of entry level "proper"  lab equipment. Square wave edges on UTG962 are 16 ns, and 4ns for SDG1000X.
On UTG962 jitter is actually better, but only at >5MHz. At below 5MHz it is 2ppm+200ps VS 0.005 ppm+300ps on SDG1000X.
UTG962 has no PWM modulation, ?
Timebase accuracy is worse on UTG962. It is a small plastic box with external wall plug type PSU.
Which can be useful if you need to carry it around and need something simple for small desk...
It would make very nice little AWG for a go bag with Micsig or Pico, together with one of those MiniWare PSU.
I agree that for most hobby users and even for pro use as a kind of "around the shop" little handy AWG, UTG962 is worth it's money.
Most people will never need more.

But the SDG1000X is more expensive for a reason, as are Rigol entry level AWG.  Is it worth the money difference, is up to every one to decide for themselves.
