[Discuss-gnuradio] Setting Intermediate Frequency in Python

[s k]

I am using this code to set an intermediate frequency in Python platform:

usrp = uhd.usrp_source(device_addr = addr, io_type = uhd.io_type.COMPLEX_FLOAT32, num_channels = 1)

usrp.set_rx_freq (0, 1.03e9)

but I am getting an error as:

AttributeError: 'uhd_usrp_source_sptr' object has no attribute 'set_rx_freq'

But i saw this in some USRP documents. Is this an old and out of use code? How can I set the IF.

(My purpouse of using IF is cancelling the unreal center peak. http://lists.gnu.org/archive/html/discuss-gnuradio/2012-08/msg00032.html)
