I just sold my fy6600. I rarely used it due to ground problems. Many contributors mods this model (power supply, final amp) to compensate "light" engineering.
Are actuals products mature ?

Looking at the Amazon ad, I see a two-prong power plug, so I'm not surprise that the first problem addressed by https://www.paulvdiyblogs.net/2019/09/upgrading-tuning-my-fy6600-waveform.html
is the SMPS ground noise. Other problems are not so obvious unless you own one. For audio frequencies, I would just use a PC software, perhaps a USB device. But the "pros" like Keysight, Tektronics etc. will not have these problems, but they are expensive.
This lesson applies to any audio product, ie a "universal 80-240V" power supply MUST have a 3-wire grounded power cord.
Note that most modern scopes include such a signal generator.

I think the winner is an australian manufacturer with appparatus without switch and power supply without earth !
I didn't know this link, thanks. Seems that new model 6900 have also power supply problem (not only), even with 3 poles power supply:

I would like to use generator for logic and audio where high precision is not mandatory.
