  2. EMF measurement - Wikipedia

    en.wikipedia.org/wiki/EMF_measurement

    frequency selective measurements: in which the measurement system consists of a field antenna and a frequency selective receiver or spectrum analyzer allowing to monitor the frequency range of interest. EMF probes may respond to fields only on one axis, or may be tri-axial, showing components of the field in three directions at once.

    en.wikipedia.org/wiki/Antenna_analyzer

    An antenna analyzer measuring SWR and complex impedance of a dummy load. MFJ-269, MFJ Enterprises Inc. An antenna analyzer or in British aerial analyser (also known as a noise bridge, RX bridge, SWR analyzer, or RF analyzer) is a device used for measuring the input impedance of antenna systems in radio electronics applications.

  4. 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. 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. Detector: RMS (NOT Peak.

  7. Network analyzer (electrical) - Wikipedia

    en.wikipedia.org/wiki/Network_analyzer_(electrical)

    ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...
