As everyone knows, Electro Magnetic Compatibility both comprised electromagnetic radiation characteristic, comprised again the requirement of electromagnetic immunity characteristic.With electromagnetic radiation characteristic, only have the electromagnetic radiation characteristic of each equipment to meet the requirements in electronic system, the electromagnetic radiation characteristic of the whole electronic system of guarantee meets system requirements.In equipment R&D process, if the electromagnetic radiation source in energy quick position equipment on pcb board, so just may utilize the means such as layout designs, wires design or circuit design, reduce the electromagnetic radiation characteristic of pcb board, thus the electromagnetic radiation characteristic of whole electronic system is made moderate progress.
The existing standardized test platform checking pcb board electromagnetic radiation characteristic at present, test result is accurate, but the instrument and equipment that this test platform relates to is more, and testing procedure is loaded down with trivial details.In pcb board R&D process, the accurate results of standardized test platform is not needed time most of, just need the approximate location determining electromagnetic radiation source on pcb board fast, after layout regulation, wiring or circuit structure, again observe the improvement situation in this electromagnetic interference source, go round and begin again, until the electromagnetic radiation characteristic of pcb board meets the demands in equipment, standardized test platform is adopted accurately to measure again, thus the accurate electromagnetic radiation characteristic of equipment.
So, in equipment R&D process, need a kind of can the instrument of electromagnetic radiation source of quick position pcb board, positioning result is roughly accurate, but easy and simple to handle, is convenient to repeat.
Utility model content
The utility model provide a kind of can the instrument of electromagnetic radiation source of quick position pcb board, meet the requirement that in equipment R&D process, needs repeat, easy and simple to handle, positioning result is roughly accurate, it is characterized in that, electromagnetic radiation characteristic scanning board is positioned at cuboid cover top portion, and spectrum analyzer, touch display screen, ON/OFF key, spectrum scan startup/Pause key, spacescan startup/Pause key are positioned at cuboid outer casing frontispiece, and attaching plug is positioned at cuboid shell rear surface.
Described cuboid enclosure, microcontroller connects power module, spectrum scan control module respectively, touches display control module, scanning board control module, spacescan control module.
Described electromagnetic radiation characteristic scanning board is controlled by scanning board control module, and spectrum analyzer is controlled by spectrum scan control module and spacescan control module.Electromagnetic radiation characteristic scanning board, for scanning tested pcb board, can obtain the electromagnetic radiation characteristic of tested pcb board within the scope of 20Hz-2GHz, or the spatial radiation characteristic of tested pcb board on certain Frequency point within the scope of 20Hz-2GHz.Electromagnetic radiation characteristic scanning board and spectrum analyzer with the use of, the electromagnetic radiation source position of pcb board can be located, and provide electromagnetic radiation source strength.Wherein electromagnetic radiation characteristic scanning board can adopt EMSCAN electromagnetism test scan plate, and spectrum analyzer can adopt the FSL series spectrum analyzer of R & S company.
Described touch display screen is for showing the spatial radiation characteristic of tested pcb board on certain Frequency point within the scope of electromagnetic radiation intensity curve within the scope of pcb board 20Hz-2GHz and 20Hz-2GHz, tangible operation, controlled by touch display control module, and be connected with microcontroller.
Described ON/OFF key is used for the opening and closing of control analysis instrument, is controlled, and be connected with microcontroller by power module.
Described spectrum scan startup/Pause key, for controlling startup and the time-out of pcb board spectrum scan, can be measured the electromagnetic radiation characteristic of pcb board, be controlled, and be connected with microcontroller by spectrum scan control module within the scope of 20Hz-2GHz.
Described spacescan startup/Pause key is used for controlling after completing spectrum scan, and the spacescan of the Frequency point of the electromagnetic radiation peak value obtained from pcb board electromagnetic radiation characteristic curve, is controlled by spacescan control module, and be connected with microcontroller.
The beneficial effects of the utility model solve in equipment R&D process, need repeatedly, the electromagnetic radiation source position of pcb board and the requirement of intensity in quick position equipment, avoid the complex steps of building standard testing platform, test platform is integrated into an instrument, this instrument can the electromagnetic radiation source of quick position pcb board, positioning result is roughly accurate, but easy and simple to handle, is convenient to repeat.
