Catch those elusive if needed high-speed transients with ScanEM-C probes The standard radiated EMC test is done in the far field, 10 (3m) from the product. Electromagnetic interference (EMI) and electrostatic discharges (ESD Events) can lead to This test tells if the product fails, but cannot point to the source of the problem. It is yield losses, malfunction of electronic equipment, and component damage.
