2. Spectrum analyzer - Wikipedia

   en.wikipedia.org/wiki/Spectrum_analyzer

   Spectrum analyzers are widely used to measure the frequency response, noise and distortion characteristics of all kinds of radio-frequency (RF) circuitry, by comparing the input and output spectra. For example, in RF mixers, spectrum analyzer is used to find the levels of third order inter-modulation products and conversion loss.

3. 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.

4. RF probe - Wikipedia

   en.wikipedia.org/wiki/RF_probe

   RF probes are especially relevant for switches and RF traces in printed circuit boards as well as terminations of RF components. In such systems, like many other RF circuits, there is a higher requirement of matching probe impedance with that of the DUT. Efficient matching avoids reflection which in turn leads to efficient power transfer.

7. 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 ...
