External LO in TDD

Hello. Is there a detailed guide on using external LO source with AD9361 in TDD. It appears that the 9361 expects the LO to be present at certain times during initialization and in RX/TX window. This was proved by supplying a constant, non bursty LO from a signal generator. Otherwise, there are quadrature, magnitude, and phase errors in the transmit waveform. Overall, our system works. We receive and transmit with degraded EVM. Can someone help? Thanks.
