RF-B 3-2 POWDA POLE H 30 MHz up to 3 GHz

The measurement coil of the RF-B 3-2 H-field probe is set at a 90° angle to the probe shaft. By positioning the probe head vertically, the measurement coil touches the surface of the printed circuit board directly. This allows for use at places on the surface of printed circuit boards, which are typically hard to access, e.g. between large components of switching controllers. The RF-B 3-2 is a passive near-field probe which detects magnetic field lines emitted from the measured object at 90°. Magnetic field lines which enter the probe laterally are not detected. In contrast to the RF-R 3-2 H-field probe, its coil is positioned in the probe tip at a 90° angle. The near-field probe is small and handy. It has a current attenuating sheath and, therefore, is electrically shielded. It can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The H-field probe does not have an internal terminating resistance of 50 Ω.
