UNI-T UTG932/UTG962 200MSa/s Function Arbitrary Waveform Generator
valcher:
I would like to clarify what the FPGA firmware is responsible for, the control interface?
Yuriy V.:
Синтезатор (synthesizer)
onx:
This firmware UTG900E.bin doesn't have SRC check :)
We can change FW version to any we want.
Now my 3.06 changed to 1.09 :)

I don't know enough about it and I don't have such a device, but why don't you compare the information in the data sheet with your measurements?
Like "phase noise" and "shake": https://www.batronix.com/files/Uni-Trend/UTG900E/UTG900Edatasheet.pdf

because there is no value for shake at sine waves. And because I don't understand what a value of -125dBc/Hz means at phase noise.

I understand that you would prefer it if someone with an UTG932 could confirm your measurements.
I can't, but I think that some jitter is normal. It's still a cheap FG.
If you want to know more about it theoretically:
German: https://de.wikipedia.org/wiki/Phasenrauschen#Messung
Lots of background (English)

Maybe you could ask the question more generally in another subforum. Maybe "Metrology" or "Beginners", I don't know.
There are already such topics: https://www.eevblog.com/forum/metrology/phase-noise-measurement/msg3337416/#msg3337416
