Control of AD9361 ( 2R2T ) mode

Dear all

I am using AD9361(ADRV9361-z7035) in FDD Independent mode .I want to control Tx and Rx of AD9361 independently through some logic. My objective is that whenever "X" frequency is fall on Rx(detected by Rx-FFT-threshold logic ). I want to transmit this frequency on Tx ( I already done this , ) but I want to transmit that detected frequency continuously on Tx( for some millisecond ) .I inserted a logic that whenever a frequency detected . Turn Off RX path and Turn ON Tx path ( but the issue is that whenever the RX path is turn off , at the same time tone is disappear . the board is running like loopback (from RX----TX) . My requirement is that Tx keep transmitting the detected frequency for some millisecond .Any reference document or suggestion from your side .?

    Why are you turning off the RX path? Or you just interested on the frequency of the received tone, but not on the actual tone? If that's the case you can try to reconfigure the DDS's of the core to the received frequency and enable them.
