Part Number: AWR6843


Hi Expert,

from doc https://www.ti.com/lit/an/spracx7/spracx7.pdf,

few questions:

1. how do we make sure the calibration result is correct? Any close check mechanism?

2. about the "Parametric Tests", for Transmitter-Receiver Loopback SNR, customer just needs to compare the SNR with golden sample. Is there any other to be check?

3. Does TI provide production test tool?

BR,

frank

    Hi Frank,

    Sorry for the delay in sending out the response. Please find the comments.

    1) how do we make sure the calibration result is correct? Any close check mechanism?

    This can be checked by placing the corner reflector at known angles either side of the bore sight to confirm whether the calibration is working or not.

    2)about the "Parametric Tests", for Transmitter-Receiver Loopback SNR, customer just needs to compare the SNR with golden sample. Is there any other to be check?

    yes, The customer needs to compare the SNR with golden sample.

    3)Does TI provide production test tool?

    The current SDK provides a method for generating the calibration coefficients over the CLI via the OOB Demo. please refer to the SDK user guide. 

    please find the attached path  mmwave_sdk_\packages\ti\datapath\dpc\objectdetection\\docs\doxygen\html\index.html.
