Hi:
I use your company's AWR2243 cascade product. I have a few questions about calibration.
1、Document "mmwave_studio_cascade_user_guide" and "AWRx_TX_Channel_Calibration_Script_User_Guide" give the RF board directional dimension antenna calibration method and process when using MIMO and BF modes,but no detailed principles are given. If I modify the antenna layout (transmitting antenna spacing, etc.), do this set of procedures and corresponding processing procedures need to be modified? Does this process still apply? If it needs to be modified, where and how to modify it? Are there relevant reference documents?
2、On the basis of question 1, the document gives the calibration of the direction dimension, how should the calibration of the pitch dimension be handled?
3、In the document “self-calibration”, a series of RF-related part calibrations are described, and the TX phase calibration is mentioned in the document. The TX phase calibration of BF mode is also explained in document "AWRx_TX_Channel_Calibration_Script_User_Guide". Does the TX phase calibration of these two documents refer to the same calibration problem?
4、In the self-calibration document, the customer’s factory is mentioned for some calibrations such as temperature calibration. What does this part mean? Do I need to calibrate myself for temperature calibration? What is the calibration method and environment?
