Method, system and probe for measuring and visualizing values of an electromagnetic parameter of a PCB

A system for visualizing measured values of an electromagnetic parameter of a printed circuit board, PCB, comprising:

• a probe with a probe head configured to contactless measure values of at least one electromagnetic parameter at at least two different positions of the PCB;
• a camera fixed in position relative to the probe head and configured to record for each of the different positions an image of an area of the PCB around the probe head;
• a processing device configured to
• correlate, for each of the different positions, the measured values of the electromagnetic parameter with the recorded image of the area of the PCB around the probe head,
• determine a location of each of the recorded images of the areas on an map representation of the PCB, and
• superimpose the map representation of the PCB with the measured values of the electromagnetic parameter;
• and
• a visualization device configured to visualize the map representation of the PCB together with the superimposed measured values of the electromagnetic parameter.
