Abstract

The invention provides an electromagnetic radiation test method, system and device, and a storage medium. The method comprises the following steps: connecting a network port of a control computer in a control room with a network port of a substrate management controller of a tested device in a test shielding darkroom through a network cable; adjusting the corresponding frequency exceeding the limit value to the screen of the receiver, and judging whether the corresponding clock opens the spectrum spreading function or not according to the waveform on the screen; in response to the fact that the spectrum spreading function of the corresponding clock is opened, selecting an optimal spectrum spreading mode; and selecting an optimal modulation depth and an optimal modulation speed in the optimal spread spectrum mode. According to the invention, when electromagnetic radiation testing is carried out, setting of related parameters of remote control spread spectrum can be directly carried out on the server in the shielding darkroom in the control room, and testing results under different setting conditions of the spread spectrum parameters can be directly checked in real time in the control room, so that a large amount of time and economic cost are saved.

Description

technical field [0001] The present invention relates to the field of electromagnetic testing, more specifically, to a method, system, equipment and storage medium for electromagnetic radiation testing. Background technique [0002] Information technology equipment (including server products and computer products) is developing in the direction of high speed, high sensitivity, high integration, and high stability, and the requirements for electromagnetic compatibility are becoming more and more stringent. The clock frequency of digital signals is getting higher and higher, the signal setup and hold times are getting shorter and shorter, and the requirements for clock jitter are becoming increasingly stringent. Therefore, for the interconnection equipment of the high-speed digital system, the problem of electromagnetic radiation is becoming more and more prominent, which not only affects the work of the digital system at the connection end, but also interferes with other surro...
