Estimating the term…
A method and apparatus for testing near field magnetic fields of electronic devices. The method comprises measuring a magnetic field using a loop antenna that is oriented in a first direction. The loop antenna is swept through a desired range of azimuth angles while measuring the magnetic field. Once the first direction testing is completed, the loop antenna is changed to a second orientation direction. The magnetic field is then measured in the second orientation direction and is swept through a desired range of orientation angles in the second direction. The apparatus provides a loop antenna connected to a coaxial probe, with the coaxial cable serving as the center conductor, and two outer conductors. An axle is mounted to the loop antenna and connected to a step motor. A servo motor is also provided for moving the arm assembly.
