AFAIK you're correct. You need SDG6000X with IQ option and IQ-Enabled version of the SSG3000X.

Yes sorry guys.
P11 of the datasheet explains requirements.

That seems expensive...  :(

Rigol seems a much better option in $$$ terms.

norepy wanted the 20dB output capability.

Yes, but there are other devices which all have 20dbm capability  ;)

I think tv was referring to the IQ options available via Siglent as being expensive  :-\

For the cost of a SSG3021X (IQ enabled) AND SDG6000X - you can buy an integrated IQ enabled RF Sig Gen + have some change for  :popcorn:

SDG6052X already can do 500 MHz IQ.

I don't have mine here to try some stuff to show you unfortunately as it's with a buddy trying out the IQ on a SSA3075X-R.  8)
tv84:
Let's do some math to check if I'm doing something wrong.

In order to have RF with IQ modulation (2.1GHz):

SSG3021X IQ (5000€) + SDG6022X (1520€) = 6520€

Rigol (2.1GHz):
Rigol DSG821A (with IQ included) = 4000€

If this is correct I would say SSG3021X IQ is overpriced! Am I right?
TurboTom:
True -- I didn't even notice that the DSG800A series offers an internal baseband generator so it can be used as a stand-alone source of an IQ-modulated RF signal. If configured like that, it will output the baseband signal at the corresponding ports at the back of the instrument. Likewise to other Rigol generators, the connectivity is superb and considerably better than Siglent's offerings can provide.

As it appears, Rigol's DSG800 series is capable of +20dbm output level as well, even though not specified. If this is the case for all models of the line and over the full bandwidth, is yet to be evaluated.

Considering that the SSG3021X-IQE can probably be up-hacked into the SSG3032X-IQE model, may make Siglent's offer appear more attractive, but since this class of instruments will rather be purchased by "professionals", hacking options are less likely to affect the decision making. If Rigol's 2.1GHz version can be "improved" to the full-bore 3.6GHz model is something I'ld rather doubt.
