|Subject:||[Discuss-gnuradio] Frequency Offset|
|Date:||Wed, 2 Sep 2009 09:14:52 +0800|
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!
