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. 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 ...

4. List of UWB channels - Wikipedia

   en.wikipedia.org/wiki/List_of_UWB_channels

   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. Use Average if RMS is not available) Sweep: 1ms/point. (In the image, 601points on the screen, 601ms sweep, so 1ms/pt.

5. 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]

6. 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.

7. 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). [1]

8. List of electrical and electronic measuring equipment

   en.wikipedia.org/wiki/List_of_electrical_and...

   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

9. Spectral density estimation - Wikipedia

   en.wikipedia.org/wiki/Spectral_density_estimation

   Spectrum analysis, also referred to as frequency domain analysis or spectral density estimation, is the technical process of decomposing a complex signal into simpler parts. As described above, many physical processes are best described as a sum of many individual frequency components.
