Re: [Discuss-gnuradio] sampling rate of USRP2

[Nick Foster]

The USRP2 is fixed at a 100MHz sample rate.

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

Hi,

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.)
