Embodiment Construction

[0038] The main concept of the electromagnetic radiation source measurement device of the present invention is to add a small part of the circuit in the electronic equipment, and realize the control of the work of each functional module in the electronic equipment under the instruction of the user, and control the operation of each functional module. Every potential source of electromagnetic radiation within the system is measured. The control of the work of the functional modules is realized by controlling the power supply of the functional units. Control of each potential source of electromagnetic radiation is achieved through the control pins of the device.

[0039] Such as figure 1 , The electromagnetic radiation source measurement device includes the following modules: a control interface unit, a communication interface unit, a core control unit, a power supply control unit, and a device control unit. When in use, the user uses the control interface to issue instruction...

Abstract

A method and device fro measuring electromagnetic radiation source in equipment, said method containing when all devices work, making EMC radiation transmission test, then allowing only one function unit to work and making EMC radiation transmission test to obtain the radiation transmission of said function unit, then allowing one device in a function unit to make EMC radiation transmission test, to obtain respectively the radiation electromagnetic strength curve of different device. By said method, the radiation electromagnetic strength curve of each function unit and device in each function unit can be obtained, finally analyzing the data. Said device contains control interface unit, communication interface unit, kernel control unit, power supply control unit.

Description

technical field [0001] The invention relates to the measurement of electromagnetic radiation sources in electronic equipment, in particular to the measurement of main electromagnetic radiation sources when many functional units in large communication equipment in the field of communication work simultaneously. Background technique [0002] EMC is the abbreviation of Electromagnetic Compatibility (Electro-Magnetic Compatibility). Electromagnetic compatibility refers to the ability of electronic equipment and systems to work harmoniously and effectively in various electromagnetic environments. The purpose of electromagnetic compatibility design is to enable electronic equipment to suppress various external interferences, work normally in a specific electromagnetic environment, and at the same time reduce its own electromagnetic interference to other electronic equipment. [0003] Electromagnetic Compatibility (EMC) testing can be divided into four categories based on differen...
