Abstract: Bidimensional electromagnetic emission level monitoring equipment for detecting the electric fields or the magnetic fields of RF (Radio Frequency) emissions from equipment under test by moving an electromagnetic probe bidimensionally. The measuring frequency, the scanning range of the probe, and the distance between measuring points are entered on a keyboard of a controller. A spectrum analyzer selectively receives RF emissions of a designated frequency from the probe in response to an instruction from the controller and feeds emission level signal data to the controller as digital signals. A probe scanning section loaded with the probe is moved bidimensionally by a motor driver under the control of the controller. The controller delivers to a display an emission level distribution signal representative of an electromagnetic distribution based on the emission level data and position data associated with the probe.

Abstract: A shielding member includes magnetic and conductive members. The magnetic and conductive members are alternately arranged. At least one of the conductive members may be replaced with an elastic conductive electromagnetic shielding member.
