ELECTROMAGNETIC NOISE MEASURING MAGNETIC FIELD PROBE, ELECTROMAGNETIC NOISE MEASURING ELECTRIC FIELD PROBE AND ELECTROMAGNETIC NOISE MEASURING APPARATUS

摘要

PURPOSE: To provide an electromagnetic noise measuring magnetic field probe and an electromagnetic noise measuring electric field probe which have small size and weight and are not affected by the influence of external noise. ;CONSTITUTION: Shielding films 6₁, 6₂, 56₁, 56₂ are provided on the front and rear surfaces of printed boards 3, 53 having a front surface, an intermediate layer and a rear surface, a coil pattern 9 or an electric field detecting pattern 59 is provided on the layer, and window opening parts 11₁, 11₂ are respectively provided at the films 6₁, 6₂, 56₁, 56₂ so that a magnetic flux or an electromagnetic wave arrives at the pattern 9 or 59 to constitute an electromagnetic noise measuring magnetic field probe 2 and an electromagnetic noise measuring electric field probe 52. Since it is formed of the boards, it can be reduced in size and weight, mounted in a probe scanner, and provided with high shielding properties.;COPYRIGHT: (C)1996,JPO
