Dear list, Little update on transmitting bursts and simultaneous receiving with USRP B210. When I connect anything that has some path between TX/RX SMA port's body and inner female sleeve contact (like 3dB attenuator or even my finger) the output signal starts to look ok. I don't know what is caus

Piotr, This is especially baffling to me, because I recall that the SKY13335-187LF switches used in B210 must be isolated from DC on all RF ports. But they are! The only components connected to the SMA connectors are a series 470pF capacitor. Perhaps the problem is exacerbated by poor impedance m

Hi all, I narrowed down when the issue occurs. When using separate sides of B210 for transmitting (i.e. TX/RX port on RF A side) and receiving (i.e. RX2 port on RF B side) everything is fine and B210 starts transmitting like i.e. X310. The problem appears when transmitting and receiving on the
