Tool/software:
Our board has four ads131m08, where one adc takes 3-phase AC voltage data and the other three take AC current data. We need to phase calibrate them. Channel 0, where the voltage data is collected, is used as the reference. The result of the test is that the phase calibration of the other two channels of the adc collecting voltage data is ok, but the phase calibration of the other three ADCs is failed.
What is the correct phase calibration process for multiple ADCs? How to ensure multiple ADC acquisition data synchronization.
