if you have the data in text form (csv,xls,txt) i hope you can attach here rf-loop, or bigger picture of the frequency plot.

Sorry I have not data string about measurement. I have take this picture with this resolution and I do not want do this work all agen, it is not as fifteen minute work. This picture have done with J.Miles HP7470A (HP-GL/2) plotter emulator (http://www.thegleam.com/) and nice Prologix USB-GPIB  (HP-IB)  adapter..

I have not programming manual for this Rohde&Schwarz spectrum analyzer so I can not send command what return trace data string via GP-IB.

Thanks rfloop for the good bode plot.  If you could, a real good help would be a harmonic content of its sine wave output; what's the SNR?

At worst,  could you just check 20 Hz, 2000 Hz, and 20,000 Hz for the audio spectrum to cover bass, mid and high frequencies to see what harmonics appear and what amplitude it is?

If your devices can sweep to the high MHz and just get a cumulative harmonic content that would be perfect!

Many thanks to Mechatrommer and the rest of the guys for your support ;D
It is a great update comparing it to the crappy - dysfunctional original software.

i've been following rcgroup's thread on hantek 8060. the generators output spec is identical to this dds3x25 but i'm not sure if they use same circuit. but i already have dso,dmm,fg so i dont need 8060 anymore, but i believe its good for money. just if i dont have the rigol+uni-t+hantek 3x25, i would get this 8060. i'll get extra... an isolated (battery powered and handheld) dso/fg.
