Hi, all
I set the frequency of USRP to be 910MHz, but I noticed that
the central frequency of the signal is 914MHz. Why there is 4Mhz frequency
offset.
I also found that there is also a signal comeing up in 896Mhz. The amplitude of
the signal in 914MHz is 20dB higher than the amplitude of the signal in 896Mhz.
I also tried to change the LO Frequency Offset from -8MHz to
+8MHz, but the frequency of the signal is still 914MHz.
Does anyone who can give me some comments and help?
Thanks a lot!
