  2. 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 ...

  3. List of UWB channels - Wikipedia

    en.wikipedia.org/wiki/List_of_UWB_channels

    In order to properly measure a UWB signal with a spectrum analyzer and compare it to the -41.3dBm/MHz, you should use the following settings. If you connect a UWB transmitter directly into a spectrum analyzer (conducted with a cable, no antenna over the air), you should get values in the -43dBm to -40dBm range.

  4. Low Frequency Analyzer and Recorder - Wikipedia

    en.wikipedia.org/wiki/Low_Frequency_Analyzer_and...

    A working model of the Low Frequency Analyzer and Recorder was delivered in May 1951 which operated with real time analysis of a frequency band of 1 to 1/2 Hz. Along with the working model was a proposal for hydrophones, cables, processing systems and beamforming so that a hydrophone array could present multiple azimuthal beams to be displayed. [7]

  5. 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.

  6. Wireless site survey - Wikipedia

    en.wikipedia.org/wiki/Wireless_site_survey

    A wireless site survey, sometimes called an RF (Radio Frequency) site survey or wireless survey, is the process of planning and designing a wireless network, to provide a wireless solution that will deliver the required wireless coverage, data rates, network capacity, roaming capability and quality of service (QoS).

    Signal analyzer: Measures both the amplitude and the modulation of a RF signal Signal generator: Generates signals for testing purposes Spectrum analyser: Displays frequency spectrum Sweep generator: Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester

  8. EMF measurement - Wikipedia

    en.wikipedia.org/wiki/EMF_measurement

    An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.

  9. Signal analyzer - Wikipedia

    en.wikipedia.org/wiki/Signal_analyzer

    Signal analyzers can perform the operations of both spectrum analyzers and vector signal analyzers.A signal analyzer can be viewed as a measurement platform, with operations such as spectrum analysis (including phase noise, power, and distortion) and vector signal analysis (including demodulation or modulation quality analysis) performed as measurement applications.
