How can we adjust the ADC rate in usrp2 in ofdm benchmark example?

Hi guy,

Thanks in advance. I am a new comer to gnuradio. Now I am handling the
project based on ofdm benchmark. I want to down-sample ADC to
2M/s(default
is 100M/s) to capture the low frequency signal, 1Mhz in our case. I
guess
the USRP capture all the signal using the maximal ADC rate by default.
Does
anyone know how to do that? Any help will be greatly appreciated.

Best,
Kay

If you specify a sampling rate of 1 MHz, the USRP will downsample for
you. No reason to worry about the 100Msps.

Which device are you using?
