Hi List,

I have been working in an example of gnuradio with UHD.
 Here it is the grc:

So, How you can see, I am transmitting a cosine with an specific frequency using UHD source-sink blocks. I hpe to see an aproximation of the cosine signal  with the same frequeny at the receiver

This is the scope at the receiver:

We are obtaining a different frequency in the cosine signal at the receiver. Anyone knows why is this happening?
Am I doing anything wrong?


Thanks in advance.

Frequency offset, most likely.    Depending on which platform you're using, carrier frequency precision is 25PPM or 5PPM.
