Which budget/mid-range AWG?

[Giallograle]

I'm a hobbyist looking for my first, preferably 2-channel waveform generator to use with my oscilloscope which will probably be the Siglent SDS804X HD.

It's principally for use with audio circuits. The ability to connect it to the SDS804X for Bode Plots looks like a plus; there is software on Github which offers this for some non-Siglent AWGs and looks as though it could be extended to the Uni-T or others.

I'm on Linux and happy to use my laptop also if it's useful for data analysis - in fact I'd probably prefer it for keeping things organised. Although I'd prefer not to have to use Windows software too much.

Devices I'm considering (prices are ex-Vat) include:

• Uni-T UTG962E ~€140 14-bit 2-channels
  Siglent SAG1021I ~€140 14-bit 1-channel
  Rigol DG812~€240 16-bit 2-channel
  Siglent SDG1032-X ~€290 14-bit 2-channels

The Uni-T looks like a lot of bang for the buck and probably fine for my purposes. The Siglent looks like an easier match with a Siglent oscilloscope, and a better unit overall which will probably do me indefinitely. It's at the top of my budget.

I'm open to any other suggestions and I'd appreciate your comments or thoughts on the choice.

Only other question is - all these units are quite a few years old - is there any likelihood that they will be updated anytime soon?

Thanks!

You might want to consider what the support is like for the products you're looking at as well.

It's principally for use with audio circuits.

The noise level of budget oscilloscopes and generators at a voltage of 1 Volt is -65 dB.
Maybe it's better to use a good external sound card for PC and software (SpectraPLUS or RMAA)?

Thanks for the advice.

I have a Motu M2 DAC (-110dB noise, up to 192KHz) which I used with REW to measure my speakers so I'm familiar with it.

Would REW's square and sine waves from the Macbook be good enough for this? I think some people still use an external signal generator for this.

Are there any disadvantages or limitations I should be aware of? I think the usable bandwidth will be limited to around 44kHZ by the DAC.

I'm a complete newbie, so take this with a grain of salt, but I believe if you pair a Siglent AWG with your Siglent scope that Bode plots will be easier to generate if that's important to you.
