Supports 30 MHz to 6 GHz. A new standard for high-frequency magnetic field measurement.
The measurement coil of the XFS-B 3-1 magnetic field scanner probe is arranged orthogonally to the probe shaft. By positioning the probe head vertically, the measurement coil makes direct contact with the surface of the printed circuit board. This allows it to be used in areas of the printed circuit board surface that are typically difficult to access, such as between large components of a switching controller. The XFS-B 3-1 is a passive near-field probe that detects magnetic field lines radiating at a 90° angle from the object being measured. Magnetic field lines entering from the lateral side of the probe are not detected. Unlike the XFS-R 3-1 magnetic field scanner probe, the coil is positioned at a 90° angle at the tip of the probe. This near-field probe is compact and portable, and it is electrically shielded due to its current-damping sheath. It can be connected to a spectrum analyzer or oscilloscope with a 50Ω input. The magnetic field probe has a built-in termination resistor.
