AWR1642BOOST: How to collect samples before they are sent to DAC/transmitter

George Denove

Part Number: AWR1642BOOST

Hi,

How would I collect samples before they are sent to the radar transmitter? I want to make sure the chirps that I am going to transmit (since I tweeted the internal BPM firmware) are what I want. I want to find the ground truth of the chirps.

Is there anyway to get a text dumping (or use some debug mode) to do this? I also use the DCA1000 capture card FYI.

Thank you!

Hi,

This is not possible. The analog signal is generated in the RF front end and transmitted. There is no conversion from digital to analog involved

thank you

Hi Cesar,

Thank you for your response.

If I change the phase of each chirp through the BPM structure, how would you recommend ensuring I am transmitting the chirps I intend to?

Thanks.

For single tx you would need to perform an RF loopback with a waveguide.

thank you
