LF Active Antenna



(Directional / Nondirectional Switchable Type)


  • Measure near magnetic field of power electronics, e.g. car, medical equipment, and robot by three axes ferrite coil antennas.
  • Measure the direction of magnetic flux using front-end circuit at each of three axes.
  • Standard calibration data provided: A2LS Accredited Calibration available (optional).
  • Combining with spectrum analyzer N9382 allows off-site measurement, e.g. car, industrial robot, AM radio, radio clock.
