Hi Ali, just like the console will tell you, 25 kS/s is simply impossible with an X310; instead, the minimum possible rate was used.
You should probably just configure your X310 to get you e.g. 500 kS/s, and then resample in digital domain. If you're hesitant to design your own decimating filter, use the "rational resampler" block and configure it to decimate by (500/25)=20.
