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 .?
ENABLE/TXNRX pin control is for TDD (Time Division Duplex) mode, where the device will transmit and receive data in different time slots. Meaning you never going to transmit and receive in the same time. Don't know if this is what you want.
