I am using an Ettus B210 to simulate some wifi signals (to test ble coexistence behavior). I want the two channels of the B210 on different wifi frequencies, but I cannot get this to work in GNU radio. I can set two different frequencies in the config but both channels are still always on the same frequency.
The documentation of the B210 mentioned: "The RF frontend has individually tunable receive and transmit chains." so this would suggest that it should be possible.
Any help on this is greatly appreciated.

According to the knowledge base: "both receive frontends share the RX LO, and both transmit frontends share the TX LO. Each LO is independently tunable between 50 MHz and 6 GHz and can be used with 1 or 2 channels; all channels using the same LO must use the same sampling parameters, including the sample rate and RF center frequency."
Thus, it is not possible to tune to two different frequencies for both transmitters or receivers. 1 Frequency for both transmitters and 1 frequency for both receivers is the only option.
