IWR1443BOOST:how to set up the three transmit antennas of DCA1000 and IWR1443 to transmit the signal in turn?

Part Number: IWR1443BOOST

Hello,

I recently learned the parameter setting of two transmit antennas (tx1 and tx3) in this e2e forum.But I don't know how to set the parameters when I want the three transmit antennas transmit signals in turn.

So could you help me set the parameters in the following two interfaces?

And the desired functionality is shown below.

Best wishes,

Thank you very much.

  • HI, there:

    1) First, you need to enable all three TX during channel configuration as below.

    Then the TX2 will no longer be gray in the chirp configuration (your first figure). 

    2)  You will program two chirp configuration.  One as you showed in your figure 1;  The second, you should change the start chirp to 1 and end chirp number to 1, and disable TX0 and enable other TX you desired.    If you want to enable three TX, then you need to program a third chirp accordingly.

    3) in Frame configuration, change the end chirp to match to your configuration in step 2).  When you increase the number of chirp, you may need to change the frame periodicity if the duty cycle becomes too big.  

    Best,
