Tx Quadrature Calibration (Tx port output power)

During the Tx quadrature calibration, we have observed signals at high power level on the active Tx ports.  I understand that we can control the Tx attenuation during Tx quadrature calibration by programming register Tx Quad Cal Atten (0x0AC).  The default configuration of this register is 0x00 (0dB attenuation).  What are the impacts on the Tx quadrature calibration performances if we increase the Tx path attenuation by programming register 0x0AC to values different than 0x00.

Thank you,
