Specifications Of The Tests For The Immunity Of The Accessible Parts Of The Casing To The Wireless Rf Communications Device - Mectron combi touch Manual De Uso Y Mantenimiento

11.3.4 Specifications of the tests for the Immunity of the Accessible
Parts of the Casing to the Wireless RF Communications Device
combi touch is designed to operate in an electromagnetic environment in which radiated RF
disturbances are under control. The purchaser or operator of combi touch can help prevent
electromagnetic interferences by guaranteeing a minimum distance between the mobile and
portable RF communication devices (transmitters) and combi touch , as recommended below, in
relation to the maximum output power of the radio communication devices.

modulation at 50% can be used because, although it
does not represent true modulation, it represents the
worst case.
