how to transmit and receive using single USRP B210

I was using two file for transmitter and receiver with different channel mappping still getting a error as "is not responding" and without channelmapping it says "Tx Busy"

can some one please help me how to transmit and receive data without error using USRP B120.

Thanks

The B210 shares a single hardware clock between the two modules. In theory the frequency of the two modules can be different, but only within a limited frequency range (which I would have to look up.)

Historically MATLAB did not support this arrangement, and to implement it you needed a custom image.

The B3xx series supports independent clocks for the two modules.

thank you for your reply.

By this do you mean we can't transmit and receive simultaneously using single B210

While transmitting and receiving using the same B210 radio, we need to use the same MATLAB session for Tx and Rx, by configuring the comm.SDRuTransmitter and comm.SDRuReceiver system objects.

When the same session is used, Tx busy status still allows us to use the USRP radio as Rx.

[Walter Roberson]

How do you deal with the fact that the B210 shares a single hardware clock between the two sides, so the two sides can only be a fairly limited frequency difference apart ?

[Karunya Choppara]

The Master clock rate, Decimation/Interpolation factor and Center frequency should be the same on both the channels. The channel can be selected using Channel Mapping parameter.
