Abstract
Noise detection devices are placed at arbitrary measurement points. A selection device switches the output of the noise detection devices and an analyzer analyzes the noise amount of the frequency component for each frequency band of radiated noise. A comparison device is made up of a storage section for storing measurement data provided by a plurality of the detection devices and a comparator, and finds a difference and a greater-than, equal-to, or less-than relationship between the noise amount analyzed by the analyzer and a predetermined value in a full band or at a specific frequency or a difference and a greater-than, equal-to, or less-than relationship between the noise amounts at two points. Output of the comparison device is displayed on a display device.
