Embedded digital processing chips are in virtually everything these days: cell phones, kitchen appliances, manufacturing equipment, magnetic resonance imaging (MRI) systems — even greeting cards. Add the Internet of Things, and the scope explodes. With the broad use of digital technology comes an enormous expansion of Wi-Fi, Bluetooth, cellular, and other forms of communication, including higher-frequency transmissions.
The result is an escalating use of technology that potentially generates unwanted interference, whether in a small, wireless-enabled sensor or a luxury sedan. They all need interference testing for regulatory compliance by organizations, whether they are engineering groups, design firms, appliance manufacturers, telecommunications companies, medical imaging vendors, or others.
