Sampling rate of USRP2


I’m using USRP2 as transmitter of DVB-T signal.
Is is possible to decrease default USRP2 sampling rate from 100MHz to
multiple of 9,142MHz?
Now I’m resampling signal but this solution is time consuming and I’m
not able to get real-time performance of modulator.
In fact I just need to slow down a USRP2 somehow. Do you have any ideas?
(I’m using UHD driver.)

The USRP2 is fixed at a 100MHz sample rate.

Are you using the polyphase resampler? Its CPU load should be
less than the “regular” rational resampler in Gnuradio.
