AD9910 3kHz BW SNR

I want to know what would be the signal / noise ratio, if the measured spectrum analyzer's  bandwidth is 3 kHz.

Frequency range - from 1.5 to 30 MHz.


In the Datasheet, on page 14 Figure 12. Narrow-Band SFDR at 10.32 MHz, REFCLK = 1 GHz.

What does it mean "SPAN 25kHz" ?
Is this the band width of a spectrum analyzer?
If "Yes", I can calculate the SNR by myself.
