EMI scanners are benchtop EMC diagnostic tools that provide visualizations of electromagnetic fields in devices like printed circuit boards and antennas. An EMI scanner is a tablet-shaped device bearing a grid of near field probes, each column corresponding to a unique probe. Rather than probing a device like a traditional near-field probe, however, EMI scanners lay flat as testing platforms on which engineers need simply place the device under test. By measuring the amplitude of the H-field (magnetic field) a device produces, an EMI scanner determines whether the instrument in question requires adjustment before undergoing EMC testing in an anechoic chamber by an accredited EMC lab.

EMI scanners can be divided into two general categories: unintentional RF emission scanners and intentional RF emission scanners. Unintentional emission scanners test printed circuit boards and other technology which might accidentally leak EMI, giving engineers real-time insight into why a design fails and the efficacy of EMI shielding. Intentional emission scanners analyze antennas and instruments meant to produce specific signals, ensuring they meet performance standards for frequency, gain, bandwidth and other parameters. Both breeds of EMI scanners reduce reliance on costly and time-sucking appointments to access anechoic chambers.

Engineers in the telecommunications, military, consumer electronics, automotive, semiconductor and medical equipment fields rely on EMI scanners to conduct pre- and post-compliance EMC testing.
