AWR1642: Any suggestion for Tx and Rx function test ?

Part Number: AWR1642


Hi 

We are looking for a way to quick verify if the Tx pin and Rx pin are mounted on the PCB perfectly on the production line. 

Any suggestion for how to verify each of the Tx pin and Rx pin if they are sending and receiving signals by reading back AWR1642 internal registers? 

Thanks!

    Hello ,

    The simplest test that can be used to verify Rx and TX paths is to do actual radar measurement using a corner reflector kept at a fixed distance in front of the radar sensor and verify the received data shows the peak at the right distance and the amplitude of the peak is as expected.
