Micro-discharge power dynamic tracking method

The invention provides a micro-discharge power dynamic tracking method. The micro-discharge power dynamic tracking method is characterized by comprising the following steps: 1) a peak power meter I and a peak power meter II are connected with a zero adjusting unit and an attenuator respectively; 2) the power of an input port of a to-be-tested part is calibrated; 3) the to-be-tested part is connected to a system of a micro-discharge detection test; and 4) in the process of the micro-discharge detection test, the output of a signal source or the top bottom level of a modulation unit is adjustedin time according to the relation between the average power and peak power read by the peak power meter I and the expected average power and peak power after calibration, so that the average power andthe peak power read by the peak power meter I are close to the expected average power and peak power after calibration. According to the dynamic tracking method, the average power and the peak powerof the zero adjusting unit
