EMC scanners are benchtop EMC diagnostic tools that provide visualizations of electromagnetic fields in devices like printed circuit boards and antennas. This tablet-shaped device bears 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, EMC 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, the scanner determines whether the instrument in question requires adjustment before undergoing EMC testing in an anechoic chamber by an accredited lab.
EMC 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 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 EMC scanners to conduct pre- and post-compliance EMC testing.
