The near-field microprobe is used to measure magnetic fields at extremely high resolution and sensitivity. The optimal distance to the object being measured is < 1 mm. The measuring coil is vertically aligned within the probe head.
The probe head is shielded against electric field coupling. A preamplifier is integrated in the probe casing. It is powered by a BT 706 Bias-Tee. The probe head is available in two different versions: 1. without protective layer: the probe head gets closer to the object being measured and measures higher signal strengths. Furthermore, the probe head is more visible and this allows a more precise positioning with respect to the object being measured. 2. with protective layer: the probe head is covered by a protective layer. The probe tip stability is increased in order to reduce possible damages to the probe head. Adjusting screws allow for manual alignment of the probe tip to the probe case. The probe supports the Langer-Scanner collision protection system. During vertical movement this function will stop the probe if it touches the device under test.
