AWR2243BOOST: measureRangeBiasAndRxChanPhase approaches

Marius Schnaubelt

Part Number: AWR2243BOOST
Other Parts Discussed in Thread: AWR1443, AWR2243, AWR1243

Dear TI Customer Support,

we are quite new to the TI radar product line and could use a little help with one problem we can’t resolve for ourselves. Our setup currently consists of the AWR2243Boost sensor board in combination with the DCA1000 streaming board. Though prior to this setup, we however utilized the AWR1443 board instead. We now could use a little assistance in figuring out how to determine the "Range Bias and Rx Channel Gain/Offset Measurement and Compensation”. For doing so, with the AWR1443, the “measureRangeBiasAndRxChanPhase” command can easily be used. Though, we failed to find any equivalent approaches for the AWR2243Boost. The corresponding section in the SDK user guide (sec. 6.8) does require the Visualizer GUI, which does not seem to be available for our sensor. Can you give us a little guidance on how to perform the calibration with this new sensor board?

Best regards

    Hi,

    First thing to note here that AWR1243 & AWR2243 devices are RF-front end only devices, i.e. it is black box device, user can't write and run their own application BUT only way to configure the RF-front end of these devices are to communicate over SPI or I2C (AWR2243 only).

    Other mmwave sensor variants (xWR1443, xWR1642, xWR1843, xWR6843) are single chip MCU (R4F core [MSS] + Rf-front end) where user can write and run their own application.

    So measureRangeBiasAndRxChanPhase CLI command is applicable for xWR1443 where corresponding application is running inside device to do appropriate action/configuration.

    For AWR2243 case, you need to equivalent approach at the Host application on the received ADC data to compensate for range bias or RX channel phase.

    Hi Jitendra,

    first, thank you for your quick reply. We are wondering whether there is any reference host side application readily available for doing so? If that's not the case then is there perhaps some documentation on how to implement it by oneselves? 

    Regards

    Hi Marius,

                   I believe you have the mcuplus mmwave SDK 4.2.0.2(https://www.ti.com/tool/download/MMWAVE-MCUPLUS-SDK) installed. In the installed directory, you would find user guide in the folder:C:\ti\mmwave_mcuplus_sdk_04_02_00_01\mmwave_mcuplus_sdk_04_02_00_01\docs. In this user guide in section 6.3 discusses in detail how to configure the command "measureRangeBiasAndRxChanPhase". The visualizer GUI can be found in the mmWave demos section or in this link: https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer/ver/4.2.0/ .

                   Also, the doxygen docs available in the folder: file:///C:/ti/mmwave_mcuplus_sdk_04_02_00_02/mmwave_mcuplus_sdk_04_02_00_02/ti/demo/am273x/mmw/docs/doxygen/html/index.html has the heading of "Range Bias and Rx Channel Gain/Phase Measurement and Compensation" which has some theory and shows how the configuration is done using the SDK. 

                   Let me know if have any further questions regarding this.

    Thanks and Regards,

    Akshay.
