Electromagnetic field measuring probe, a particular way of electromagnetic radiation and electromagnetic field component measuring device

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive probe and device of a relatively simple constitution for measuring electromagnetic fields, and a method for specifying electromagnetic-field radiating components capable of measuring the electromagnetic fields of various electric and electronic equipment actually assembled into products. ;SOLUTION: The device for measuring electromagnetic fields is provided with a horizontal probe 10, a filed intensity meter 44 connected to the horizontal probe 10, timing belts 30b, etc., to elevate and lower the horizontal probe 10, a motor 40 to rotate a winding roller 38, a motor controller 42 to control the drive of the motor 40, and a personal computer 50 to control the rotating speed of the motor 40 and the measurement of the field intensity meter 44. The horizontal probe 10 is formed of a rectangular frame-shaped core formed of a plurality of Ni/Zn-based ferrite tiles, four flat plate-shaped coils arranged at the center location of the four sides of the core and electrically connected to one, another, plywood provided in the periphery of the core, and a metal enclosure made of A1 to surround the core and the plywood.;COPYRIGHT: (C)2000,JPO
