Hello my apologies for posting my previous post in the wrong group mainly the RF. But can anyone tell me is it possible to distinguish between unintentional RF radiation by a device's CPU's clock and RF emissions being emitted (unintentional) by a RF embedded device ? The assumption is that the RF embedded device is powered on but not transmitting (ie communicating). Or is it the norm for a powered on RF device to be transmitting perhaps just a broadcast of some sort ?

Thank you
