Hi everyone, I am new to this USRP B200 board. I currently have two boards and I want to connect the Tx port of one board to the Rx port of another using a SMA cable to visualize the communication.
So I start with something available online here https://www.mathworks.com/help/supportpkg/usrpradio/examples/qpsk-transmitter-with-usrp-r-hardware.html and https://www.mathworks.com/help/supportpkg/usrpradio/examples/qpsk-receiver-with-usrp-r-hardware.html Basically, my hardware connection is Computer_1 + B200_1(Tx port) + 30 dB attenuator + SMA cable + 30 dB attenuator + B200_2(Rx port) + Computer_2 And I run the transmitter code on the computer_1 and run the receiver code on the computer_2. The transmitter light and the receiver light both turns on, so I think they are doing something. However the result I get on my receiver end on computer_2 is not good. They just look like noise. I think because I use a different kind of board, so I need to modify the gain parameters in the code. But I have no idea about how to make it correctly. I hope someone with more experience with this board can show me how to do it right. Could you please help me on this. Thank you. -Ves
