    Hi,

    Yes, this is possible,

    Depending on the different start frequencies, this can be achieved in two ways.

    If there is a larger difference between the start frequencies, different profiles can be used for each of the 3 chirps. There are 4 profile configurations available.

    If there is a small  difference in the start frequency, different start frequencies can be defined in the chirp configuration (START_FREQ_VAR)

    The ranges of the chirp configuration START_FREQ_VAR is provided in the Radar Interface Control Document available in the Device Firmware Package

    Thank you

    Hi, Cesar

    Thanks for your response, that I wants consult if a method that config one chrip with three TXs work at same time but they have different start frequency, such as in 1 chrip the Tx0's start frequency is 79.0GHz, the Tx1's start frequency is 79.1GHz, the Tx2's start frequency is 79.2GHz.

    As your advice that will use 3 chrips to achieve these three different star frequencies.

    Thanks
