AWR2243BOOST: As a spectrum analyzer/receiver

Tetris

Part Number: AWR2243BOOST
Other Parts Discussed in Thread: DCA1000EVM, AWR1843BOOST, AWR2243, AWR1843

Hi,

I want to use AWR2243Boost (with DCA1000EVM) as a receiver.

Corresponding to searched post (https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/904645/awr2243boost-capable-to-only-receive-data-and-not-transmit) I had to disable Rx antennas in mmWave Studio (and I did it), then follow device configuration process mentioned in documentation.

As a transmitting device I have used AWR1843Boost ( without DCA1000EVM).

I have configured receiver, when it comes to chirp parameters in the same way as transmitter to obtain single tone signal.

Unfortunately, I cannot receiver any signal, the only visible data (IQ Samples) after "PostProc" is noise of receiver. 

Can you give me some directions/explain how to properly receive signal ?

Best regards,

Tetris

    Hello Tetris,

    Are you using AWR2243 as a receiver? If yes, do you mean "Disabling TX antennas" in mmWave studio in your below statement?

    It would be good if you could highlight your exact sequence of steps followed. How are you configuring AWR1843 for transmitting chirps? Are you again using mmWave Studio for that purpose?

    Hello Ishita,

    sorry for my mistake and yes I meant "Disabling TX antennas"  in mmWave studio in AWR2243Boost.

    When it comes to AWR1843 for transmitting I'm using mmWave_Demo_Visualiser:

    https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer/ver/3.3.0/

    which corresponds to my SDK version (3.3).

    AWR1843 (without DCA1000EVM) - Transmitter:

    1. Go to link https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer/ver/3.3.0/
    2. Configure device setting appropriate ports mentioned in documentation
    3. Press "SEND CONFIG TO MMWAVE DEVICE"
    4. Check if any error message appears
    5. Go to "Plot" tab and observer if signal is being send and received (AWR1843 works only as transciever)

    AWR2243 (with DCA1000EVM) - Receiver:

    Set connection with device via mmWave Studio in "Connection" tab

    1. In "StaticConfig>Basic Configuration> Channel Config" disable Tx Channels
    2. In "DataConfig" follow documentation/TI training video
    3. In "SensorConfig>Profile" set values corresponding to signal transmitted from AWR1843  to obtain single tone after 'mixing' process
    4. In "Frame" zone:
      1. No of Frames: corresponding to send from AWR1843
      2. No of Chirp Loops: corresponding to send from AWR1843
      3. Periodicity: corresponding to send from AWR1843
    5. Then "Trigger Frame"

    I didn't mention setting ip address etc. steps, because it's done correctly and verified by using device as transceiver.

    Regards,

    Tetris

    Hello Tetris,

    Thankyou for the detailed information. 

    Let me discuss this internally with an expert and get back. Meanwhile, could you also attach picture of your post processed results?

    Regards,

    Hello Ishita,

    in order to extend observation time of signal I have set (in mmWave Studio) "Frame>No of Frames" to 0.

    Here is result after PostProc:

    I have attatched only one image, because rest of the captured frames were similar to the uploaded one.

    Regards,

    Hello Tetris, 

    Thankyou for the snippet. 

    The sequence of steps in your previous reply looks good and should technically work. But because there is a problem, we might have to take a deeper look at all your configuration settings. 

    Are you able to individually capture data using only one device? i.e. AWR1843 or AWR2243 alone?

    Also, what is the physical setup of both the devices and how are they oriented w.r.t each other?

    Regards,
