Aeroflex SGD-3 Digital RF Signal Generator. Would you recommend?


Looking to buy a good general purpose vector signal generator. I really need vector modulation (from IQ inputs) and generic modulation ( PSK, FSK, QAM). I think  that this Aeroflex SGD-3 fits the bill. Includes most of the options which is great. I also like that it has a nice UI and the user manual is pretty simple.

What is up with I/Q inputs tho? It has " I+, I-, Q+, Q- IN Four BNC sockets, differential inputs, 100 Ω. " Looks like there are four normal looking BNC connectors for this on the front panel. I just want to hook this thing up to a AWG with normal outputs. Would I need some kind of adapter?

Yes, that one from Aeroflex. I entered the link wrong. Already have an AWG very similar to the one you linked to. I am looking for a proper RF signal generator that I can produce QAM and SSB (and others) at up to a few GHz. Really confused about the 100 ohm IQ inputs. Never saw that before on an instrument .

If you're not in a desperate hurry Siglent have an RF gen coming out soon that apparently links together with SDG6000X models so to give IQ at higher BW's.

This Chinese site won't allow direct translation but you can copy/paste anything into a translator that needs further investigation.

Been asking when it's to be released but no definitive answer yet.

MSRP?

p.s. I wish I had 4k$ because eBay offer is Goood: You save: $52,346.91 (93% off)   :-DD
