    摘要: A junction-current probe is provided which can measure a current flowing in a junction port adapted to connect a circuit board or an electronic apparatus to a chassis under the condition that the circuit board or electronic apparatus is packaged to the chassis. Structurally, the current probe has a circular or rectangular insulator having a hole in the center, a coiled conductor wire for converting linkage flux into voltage, an insulating member for preventing the insulator from making electrical contact with surroundings, an extraction lead for connecting opposite ends of the conductor wire to a cable and the cable for connection to a measurement unit. The current probe is reduced in thickness within in a range in which the condition of packaging to the chassis can remain unchanged.

    摘要: An apparatus for measuring the magnitude of an electric field having an antenna open to the field. The antenna is connected to a data converter which generates an output signal proportional to the magnitude or power of the electric field detected by the antenna. The data converter provides an output signal to a memory unit which stores the magnitude of the electric field. The data converter and memory unit are contained within a housing and the antenna protrudes outwardly from that housing so that the housing and antenna may be positioned within the area of the electric field.

    摘要: A magnetic field probe apparatus includes a loop-like conductor and feeder lines spaced at a distance from the loop-like conductor. The shape of the loop-like conductor and the arrangement of the feeder lines are adjusted in such a manner that the resonance frequency determined by the combination of the inductance of the loop-like conductor line and the capacitance formed between the looped-conductor and the feeder lines, is matched to the frequency of the magnetic field generated by and in the vicinity of a measurement object (e.g. electronic device) or the frequency of the electric signal which generates the magnetic field. With the magnetic field probe apparatus according to this invention, the magnetic field in the vicinity of the measurement object can be measured with high sensitivity.

    摘要: Provided is a current probe which reduces, in current measurement, a measurement error due to an unnecessary magnetic field generated from a subject not to be measured, said subject being adjacent to a subject to be measured. The current probe is characterized in having: a sensor that detects a magnetic field; a transmission path connected to the sensor; and a pair of conductive members, which protrude toward the front from a leading edge portion of the sensor, and are provided to face the sensor. The current probe is also characterized in that a front portion of the sensor, said portion being surrounded by the protruding portions of the conductive members, is opened in the direction of a plane that faces the conductive members.
