    what is the pulse emission rate (sampling frequency) for X4M200? How fast is it transimitting frequesncy? can this be tempered with?. from previous results it seems that its about 3 HZ to me. but i want to make sure.
    Thanks.

    Hi Anwar,
    Your questions are very good, but I think you mix some concepts together.
    Please check X4 datasheet for the following concepts:
    1. Sampling rate
    2. PRF: Pulse Repetition Frequency
    3. TX center frequency
    4. FPS
    5. frame rate
    X4 user guide provide introduction on how to use the above parameters. I believe it will help you to understand them better:
    https://www.xethru.com/community/resources/xethru-x4-radar-user-guide.149/

    X4M200 hase frame rate 17FPS for baseband data message, the appliciation level messages are output per second.

    Feel free to follow if you have anything unclear.

    1. Sampling rate --> 23 GS/s
    2. PRF: Pulse Repetition Frequency --> I think in [ us ]
    3. TX center frequency--> about 8GHz
    4. FPS ---> In the python code it is set to 10FPS, but when I recorded it with a timer, I was only getting 4 frames per second
    5. frame rate --> I found an equation, but not a fixed value.
      Am I wrong? how many of those parameters can be modified from the code?
      note: I am using XEP_X4M200_X4M300_plot_record_playback_radar_raw_data.py. @Charlie Shao
