Measurement setup

Connect to a suitable spectrum analyzer or oscilloscope with a 50 ohm input. Keep probe orientation, distance and instrument settings consistent when comparing design revisions. Near-field readings help locate sources and coupling paths during EMC development.


Near-field probe techniques from Langer

Langer demonstrates probe tip shapes, correction curves and time-domain measurements. The tutorial covers general probe technique.
