hi all ,
I found something that maybe will help me solving my problem which is tune_request_t struct
can anyone give me a hint about how can i use it
Have you looked in the UHD manual?
Or the Doxygen?
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!
Cheers,
Ben
