The SX-R 3-1 is a passive near-field probe. The probe head is very small and therefore suitable for detection of magnetic-field distribution, e.g. at ICs. Because of its compact design, the SX-R 3-1 can be used at hard to reach spots ,e.g. between components. It has a current attenuating sheath and its upper side is electrically shielded. It can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input.
