In the same way that GNU Radio uses complex samples, USRPs also deliver complex baseband samples; thus, 25 MSPs of complex baseband gives you 25 MHz of bandwidth.

I'm getting confused with the concept of "Sampling rate" to set the

Nyquist theory is not respected. How come?

GnuRadio uses complex (I & Q) samples.  This results in twice the data
per sample, satisfying the Nyquest criterion.
