I have got the EV-Radar MMIC 2 board. I am trying to do some preliminary test according to the user guide by attaching 2 antennas and observing the baseband signal on the scope/spectrum analyser. It looks like I am not getting any chirp signal out from the transmitter. If I move my hands above the antennas (both) I get signal which probably is CW return due to LO leakage. Is there any test I can perform to ensure the transmission port is operating properly?
