Hi TI expert,

As title, does IWRL6432 supports self calibration like the one "Self-Calibration of mmWave Radar Devices (Rev. C)" for IWR6843?

Hello.

IWRL6432 has multiple calibration process that run. There is ATE calibration, factory calibration, and runtime calibration. What youre probably looking for is the calibrations done during run time, which the 6432 does have and do.

Hi Pedrhom,

Thanks for the explanation. Where can I find the document of run time calibration and how can I enable/modify it?

Hello,

Within the MMWAVE-L-SDK documentation, there will be documentation covering calibration and its respective software functions that configure it.

Hi Pedrhom,

Thank you for the reply. However, could you show me where the SDK 5.4.0.1 document talking about self-calibration and which part of the code is used to enable or disable it? I can't find it.

Hello,

C:\ti\MMWAVE_L_SDK_05_04_00_01\source\control\mmwave\src\mmwave_link_xWRLx4xx.c has the code you are looking for.

Hi Nafisi,

Thank you that I can locate the code now, but I can't find corresponding documentation to explain how the "self-calibration" works. Please do me a favor to provide the folder path.

Hello,

You can find details on all the different calibration types in our Self-Calibration appnote, as mentioned in your initial post

Note that although the devices mentioned are almost entirely 6843 and older, the methodology and how they work is the same
