  2. Spectrum analyzer - Wikipedia

    en.wikipedia.org/wiki/Spectrum_analyzer

    A spectrum analyzer is also used to determine, by direct observation, the bandwidth of a digital or analog signal. A spectrum analyzer interface is a device that connects to a wireless receiver or a personal computer to allow visual detection and analysis of electromagnetic signals over a defined band of frequencies.

  3. Signal analyzer - Wikipedia

    en.wikipedia.org/wiki/Signal_analyzer

    A signal analyzer is an instrument that measures the magnitude and phase of the input signal at a single frequency within the IF bandwidth of the instrument. It employs digital techniques to extract useful information that is carried by an electrical signal. [1] In common usage the term is related to both spectrum analyzers and vector signal ...

  4. Spectral analysis - Wikipedia

    en.wikipedia.org/wiki/Spectral_analysis

    Spectrum analyzer, a hardware device that measures the magnitude of an input signal versus frequency within the full frequency range of the instrument; Spectral theory, in mathematics, a theory that extends eigenvalues and eigenvectors to linear operators on Hilbert space, and more generally to the elements of a Banach algebra

    Using a spectrum analyzer in the field [ edit ] A spectrum analyzer is basicly a wide-band receiver displaying the frequency domain, showing amplitude vs frequency, where an oscilloscope shows the time domain as voltage vs time, In the field it can be used to check & aim antennas, look for interference sources, and to detect & measure a ...

  6. Radio-frequency sweep - Wikipedia

    en.wikipedia.org/wiki/Radio-frequency_sweep

    A spectrum analyzer is a standard instrument used for RF sweep. It includes an electronically tunable receiver and a display. The display presents measured power (y axis) vs frequency (x axis). The power spectrum display is a two-dimensional display of measured power vs. frequency. The power may be either in linear units, or logarithmic units ...

    1. Go more natural. Decorations that come from nature, like berries and pine branches and pine cones, give your house a holiday feel without as much ornateness, according to Baker.

  9. Optical spectrometer - Wikipedia

    en.wikipedia.org/wiki/Optical_spectrometer

    In general, any particular instrument will operate over a small portion of this total range because of the different techniques used to measure different portions of the spectrum. Below optical frequencies (that is, at microwave and radio frequencies), the spectrum analyzer is a closely related electronic device. Spectrometers are used in many ...
