Hi Rahul, ah! With that information (wrong frequency for daughterboard) it all makes sense. However, UHD will usually print a warning about not being able to tune to the frequency. Now, is it possible that you only copy and pasted a part of your program's output? Otherwise, we'll have to look into marking that a bug (but that would be really surprising)
