According to the measurement of TI shows that after calibration by calibration resistance, measuring the complex impedance phase impedance of the other, you just need to minus the phase Angle of calibration resistance, three the calibration of resistance on the phase Angle should be similar to, but the actual testing found that the difference in their phase Angle, sometimes reached around 6 ~ 7 °, this kind of situation in AFE4300EVM - PDK suite and our own development on the board has found, could you tell me what causes?
