Have you looked in the UHD manual? http://files.ettus.com/uhd_docs/manual/html/general.html#tuning-notes Or the Doxygen? http://files.ettus.com/uhd_docs/doxygen/html/structuhd_1_1tune__request__t.html > > another question is that if i used the function > tune_request(target_freq,lo_offset) setting the policy to manual , in this > particular case can i set the target frequency (which i think is the PLL > frequency) as is and change only the LO(NCO) > The target frequency is the frequency you are interested in centering at. The advantage of tune_request is that it will let you tune with an offset, so the DC component is laid right on top of your frequency of interest. Also, these questions are UHD-specific, and are not GNU Radio related. In the future, try to direct these questions to the usrp-users list, which would be a better audience / venue. Also, you seem to be e-mailing your questions to the list twice. If you forget to add a subject, just don't worry about it. One e-mail without a subject is better than spamming the list with the same question multiple times!
