摘要： In order to direct a probe having directivity that a received band is widened in accordance with a measurement distance, toward a DUT, shift the received band of the probe in sequence, receive electromagnetic, and measure electromagnetic interference, a plurality of long and short measurement distances between the probe and the DUT are set, and measurement at the long measurement distance and measurement at the short measurement distance are performed plural times. Herein, the measurement at the short measurement distance is performed on a received band where electromagnetic interference is measured by the measurement at the long measurement distance. Thus, measurement of electromagnetic interference can be performed with high accuracy in a short time.

摘要： An electromagnetic wave measuring method is provided that is capable of performing high-precision measurement in a shorter time and in a greater variety of frequency bands than heretofore with a comparatively simple configuration. A plate-like antenna (13) of which the outline shape of an opposed surface opposite a measured object (5) is similar to the outline shape of an opposed surface of the measured object (5) is brought close to the measured object (5), and an electromagnetic wave from the measured object (5) is measured based on the frequency spectrum of a received signal received by the plate-like antenna (13).

摘要： Based on a relationship between cutting-and-removing amounts for partly cutting out a stub of a pattern line and impedances of a matching circuit, a cutting-and-removing amount for adjusting the impedance to a target value is determined by simulation or by comparison operation of an impedance measured value with information stored in a database. Then, based on the determined cutting-and-removing amount, the stub of the pattern line is partly cut and removed so that the impedance is adjusted to the target value.
