[Discuss-gnuradio] Do RX and TX of USRP2 work independently ?

[김보미]

Hello :-)

 

I am using USRP2 with RFX2400.

 

I know that TX and RX work independently.

But the result of my experiment says that it doesn’t work properly.

 

The result is as follows.

 

The signal is transmitted as below. (Fc=2.45GHz Fs=4MHz)

 

 

 

 

 

 

 

The right figure is seen through the spectrum analyzer.

 

When RX is directly connected to TX, FFT plot of RX is as below.

 

 

 

 

 

 

 

 

 

 

 

But, When RX is connected to nothing, it looks more like the transmitted signal.

 

 

 

 

 

 

 

 

Could you tell me how to understand this situation?
