Combined Equipment is the physical connection between a radio system and a device which – considered separately – falls within the scope of another directive (e.g. Machinery Directive, EMC Directive, Medical Devices Directive).This could be a washing machine with Bluetooth module or an industrial printing system with Zigbee module. Before the introduction of RED, combined equipment was often considered separately with regard to the individual components, but now the focus of RED is on the end product. In addition to the obligatory measurements regarding the radio spectrum, RED may also include other measurements that have not yet been considered for the entire device.
