ADRV9009 HDL Code insert TX signal to trigger RX receiver

Hello,

I am using the ADRV9009 Evalboard with ZCU102 Board.

I connected the TX and the RX together using a SMA cable.

I can receive the sent waveform but the sent RF-pulse does not Start at Time 0.

This is changing from run to run. The reason is, that the TX and the RX are not synchronized.

I want to add a signal to connect the TX to the RX that can be used to synchronize the RX to the TX.

I can think of a trigger signal that sets the receiver memory address to the start-address.

May you please help me find a way to implement this?

Best regards,

Philipp
