Radio frequency interference can come from intentional transmitters, faulty electronics or equipment that was never intended to radiate at all. This guide explains common RF interference sources and how professional investigation separates the source from the symptom.
Modern electronic equipment can generate broadband or discrete RF energy through switching edges, oscillators, poor filtering or faults.
Industrial environments combine high-power switching, long cables, motors and control systems, creating many possible coupling paths.
A legitimate transmitter can still cause a problem through overload, harmonics, intermodulation, poor installation or proximity.
Seeing an unwanted signal on a spectrum analyser is only the beginning. A useful investigation correlates frequency, time, location and operating conditions until the source can be demonstrated.
RFI means radio frequency interference: unwanted RF energy that degrades, disrupts or changes the operation of a radio, wireless or electronic system.
Yes. Power supplies, drives, digital electronics, lighting and faulty electrical equipment can all generate RF energy even though transmitting is not their intended function.
Use the RF Interference Investigation service and provide the affected equipment, symptoms, location, timing and any patterns already observed.
Send us the symptoms, equipment involved, location and what has already been tried. We will review the requirement and advise on the appropriate paid engineering service.
