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 and the attenuator of the micro-discharge testing system are dynamically tracked, and the outputs of the signal source and the modulation unit are adjusted, so that the accuracy, reliability and safety of the micro-discharge effect test are improved.
Description
technical field [0001] The invention belongs to the technical field of microwave device testing, in particular to a dynamic tracking method for micro-discharge power. Background technique [0002] The microdischarge effect is a resonant vacuum discharge phenomenon that occurs between two metal surfaces or on a single dielectric surface. It is excited by a radio frequency electric field, usually in a microwave system under vacuum conditions. The conditions under which it occurs vary depending on the type of microdischarge, and occur when power, frequency, and the gap size of the device's internal structure satisfy a certain relationship. The occurrence of this phenomenon is related to factors such as vacuum pressure, processing technology, surface treatment, materials, and pollution. [0003] When microdischarge occurs, it will bring defects such as increased noise floor and signal deterioration, and even cause permanent damage to microwave devices. For communication, navi...
