  • The Function of Electromagnetic Interference Spectrometers

    The Function of Electromagnetic Interference Spectrometers

    One of the most common ways to detect electromagnetic interference is using a Broadband RF field meter. This is handy for finding the source of the EMI and. Strictly speaking, a spectrometer is any instrument used to view and analyze a range (or a spectrum) of a given characteristic for a substance (for example, a range of mass-to-charge values as in mass spectrometry), or a range of wavelengths as in absorption spectrometry like nuclear magnetic. Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. EMI may come from nearby electronic devices, power lines, or radio transmitters and can cause serious errors in sensitive. A Fourier-transform (FT) spectrometer generates the spectrum of its source radiation by modulating the radiation in the time domain through interference, which is then Fourier transformed. Here, a general overview of its operation is presented.
