    Can X4M200 support pulse doppler data output? And what is the range of the slow-time and fast-time frequencies?

    Thanks ,

    Hi Gary,
    X4M200 support pulse doppler data output, please refer to Module Connector Matlab example: X4M200_X4M300_plot_pulsedoppler_matrices.m.
    The range fo the slow-time and fast-time frequencies is -8.5Hz to 8.5Hz

    Hi Charlie,

    Thank you for your kindly reply.

    I have another question. I get the raw data ('.dat' file) directly from XeThru Explorer . But I want to know where I can set the parameters such as sampling frequency, CarrierFrequency ?

    Thanks ,

    Hi Gary,
    X4M200 should have a fixed sampling frequency, CarrierFrequency to make it compatible with its antenna design, these work together to make X4M200 meet FCC/ETSI regulation, but it is possible to change them by modifying X4 chip registers. Please read X4 chip datasheet. There is an example of how to write/read x4 registers in Module Connector: regmap_example.py.
