[USRP-users] How to visualize a band of precisely 8 MHz, with USRP2 and Simulink?

I need to use and visualize a band of precisely 8 Mhz, with the center
frequency 628 MHz (DVB-T), on my USRP2, working in Simulink.
The problem is that I would need a decimation factor of 12.5 (1e8/12.5 =
8e6 MHz), in order to achieve this, and all specifications say that the
decimation value needs to be an integer between 1 and 128.
Is there a way around this problem?
Using the 12.5 decimation value, doesn't return an error, the power
values I get seem to be congruent with what would be expected, but when
visualizing the band, it appears to be distorted.
Are the power values trust worthy, or are they just like the visualization, distorted?
Should I use a combination of FIR decimators and FIR interpolators? If so, how?
