Power supply ripple interference test method and system

Abstract

The invention provides a power supply ripple interference test method and system. The method comprises the steps of: obtaining preset parameters, carrying out initialization self-checking according to the preset parameters and an excitation parameter and outputting a power supply ripple, wherein the preset parameters comprise a frequency value of the point to be tested and a standard level value corresponding to the frequency value of the point to be tested, and the excitation parameter comprises an excitation amplitude value corresponding to the frequency value of the point to be tested and the standard level output value; and testing the equipment to be tested, and carrying out real-time verification on the power supply ripple. The system comprises an initialization self-checking module and a real-time verification and test module, wherein the initialization self-checking module is used for obtaining the preset parameters, carrying out initialization self-checking according to the preset parameters and the excitation parameter and outputting the power supply ripple; and the real-time verification and test module is used for obtaining the power supply ripple, testing the equipment to be tested, and carrying out real-time verification on the power supply ripple. By adopting the method and system, the testing efficiency and measurement accuracy are effectively improved, therefore, the efficiency and accuracy requirements in a power supply ripple interference test process of automobile electronic equipment are met.
