Re: [Discuss-gnuradio] Setting Intermediate Frequency in Python

[Schantin, Andreas]

Hallo Sema,

 

I believe the function you are looking for is called set_center_freq, when using the gnuradio interface to the USRP. So it should be:

 

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

usrp.set_center_freq(1.03e9, 0) # Passing the channel as an argument is optional

 

Regards

 

Andreas

Betreff: [Discuss-gnuradio] Setting Intermediate Frequency in Python

 

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)
